Texto completoResumen
Introduktion: Tandlöshet är ett problem som drabbar många människor. Kraven på funktionella och snygga tänder i livets alla skeden har blivit tydligare på senare år. Dentala implantat är en möjlighet att ersätta förlorade tänder och har hjälpt många individer att få sin livskvalité tillbaka.
Syfte: Att kartlägga mjukvävnads- och hårdvävnadskomplikationer som kan uppkomma efter en behandling med dentalt implantat och vilka orsaker det finns till dessa.
Frågeställningar: Vad finns det för mjukvävnads- och hårdvävnadskomplikationer som kan uppkomma efter en behandling med dentalt implantat?
Vad finns det för orsaker till komplikationer efter behandling med dentalt implantat?
Metod: Studien är en systematisk litteraturstudie.
Resultat: Efter behandling med dentalt implantat kan olika mjukvävnads- och hårdvävnadskomplikationer uppstå. De två vanligaste mjukvävnadskomplikationer var peri-implantär mukosit och mukosal hyperplasi. Typiska hårdvävnadskomplikationer som upptäcktes var benförlust och apikal peri-implantit. Tidigare parodontiterfarenhet visade sig vara den viktigaste orsaken till komplikationer vid dentala implantat.
Konklusion: Dental implantatbehandling är inte riskfri. Studien visade att komplikationer är vanliga efter dental implantatbehandling samt att det fanns riskfaktorer som påverkar dental implantatbehandling på ett negativt sätt.

Texto completoResumen
INTRODUCCIÓN:
Cuando se coloca un implante, se asume que habrá una pérdida de hueso en la zona más coronal alrededor de este.
La colocación del implante respecto al nivel de hueso ya sea crestal o subcrestal y el tipo de conexión elegida, ya sea conexión externa o interna, se han relacionado como algunos de los factores causantes de la pérdida de hueso alrededor de implantes. La preservación del hueso periimplante, es fundamental porque influye sobre la forma y el contorno de los tejidos blandos suprayacentes, que son importantes para el resultado estético del tratamiento y para el éxito de los mismos.
El objetivo principal de esta tesis fue evaluar la pérdida de hueso marginal tanto en implantes de conexión externa e interna, como en implantes colocados a nivel crestal y subcrestal. Se ha sugerido que en la conexión externa y en la colocación subcrestal de los implantes existe mayor pérdida de hueso marginal, sin embargo, la literatura no es clara al respecto. Por este motivo se realizaron dos revisiones sistemáticas para responder a las siguientes preguntas: “En pacientes tratados con implantes dentales, ¿hay diferencia entre la conexión externa e interna en términos de pérdida ósea marginal alrededor de las conexiones? y ¿hay diferencias entre la colocación subcrestal y crestal en términos de pérdida ósea marginal?
En la primera revisión se analizaron las conexiones. Se incluyeron 10 artículos que incluían 1.523 pacientes con 3.965 implantes. De acuerdo con esta revisión y considerando las limitaciones debidas a los grados de heterogeneidad entre los estudios incluidos, ambas conexiones presentaron altas tasas de supervivencia. Así todo y que la conexión interna es la que parece gozar de mayor reconocimiento en la actualidad; los estudios incluidos en esta revisión, caracterizados por un gran número de muestra y largos periodos de seguimiento demostraron que la conexión externa era una conexión fiable, avalada por estudios de longevidad.
Respecto a la segunda revisión y metaanálisis, en la que se analizó la colocación a nivel crestal o subcrestal de los implantes, se obtuvieron resultados clínicos apropiados.
Teniendo en cuenta la falta de evidencia científica en ambos aspectos y con la intención de poder aportar claridad a la hora de elegir la conexión del implante y su posicionamiento vertical respecto al hueso, planteamos la realización de un ensayo clínico aleatorio, con el objetivo de determinar si la pérdida de hueso difería significativamente entre las dos conexiones y las posiciones verticales del implante.
MATERIAL Y MÉTODO :
Los pacientes fueron reclutados del Máster de Medicina Cirugía e Implantología Oral. Facultat de Medicina i Ciencies de la Salut (Odontología). Y fueron atendidos en el Hospital Odontològic Universitat de Barcelona (HOUB).
Se realizó un ensayo clínico aleatorizado, con un tamaño muestral de 93 implantes (31 de conexión externa y 62 de conexión interna: 33 con diseño para colocación infracrestal y 29 crestal) colocados en 27 pacientes. Se realizaron controles radiológicos el día de la colocación de implantes, al mes y durante la realización de las coronas, también se tuvo en cuenta el Análisis de Frecuencia de Resonancia (AFR) el día de la colocación del implante, cuando se colocó el pilar de cicatrización y durante la realización de la prótesis.

Texto completoResumen
La visita al dentista ha sido tradicionalmente reconocida con un evento desagradable y doloroso, esta idea perdura hoy en día a pesar de la creciente preocupación de los profesionales por crear ambientes cómodos y de confianza junto con el empleo de técnicas alternativas. La ansiedad por acudir a la consulta dental cuenta con una prevalencia en la población general que ronda el 50% . La alta incidencia reportada por diferentes estudios ha llamado la atención de psicólogos y odontólogos por las consecuencias directas en la salud oral y en el bienestar de los pacientes. Por esto creamos un nuevo concepto de tratamiento odontológico en el cual se adicionan terapias alternativas para disminuir la ansiedad y el stress antes, durante y después del tratamiento odontológico. DENTAL PLACE se basa en mejorar la estética dental ofreciendo lo mejor en tratamientos odontológicos interrelacionando con la reflexología y acupuntura, técnicas de medicina alternativa que ayudarán a relajar a los pacientes. DENTAL PLACE, es una clínica enfocada en cambiar la ansiedad y el stress que genera la consulta, empleando métodos y técnicas diferentes. Nos basamos en estudios de medicina complementaria, en el optimismo y el buen humor para cambiar el concepto de la ansiedad . Daremos tratamiento al 20% de los pacientes que presentan niveles altos de estrés y temor a la consulta odontológica. La clínica estará ubicada en el distrito de San Borja y brindará sus servicios a toda persona que lo requiera. En el primer año esperamos atender a 1.5% de nuestro mercado objetivo que equivalen a 1,560 atenciones aproximadamente. Para el quinto año esperamos atender al 5.2% el cual equivale a 6,500 atenciones. Nuestro mercado objetivo son personas pertenecientes a los Niveles Socioeconómicos (NSE) A y B, ya que son los que tienen mayor poder adquisitivo y son más afines a nuestros plan de marketing. Nuestro segmento de mercado requiere un plan de marketing agresivo. Por eso dentro de nuestro plan está la promoción por medios de comunicación como la radio y televisión y medios escritos. Nuestra propuesta de valor para el cliente es incorporar terapias alternativas como son acupuntura y reflexología, orientados disminuir y eliminar el uso de anestésicos locales, que está demostrado que incrementa los niveles de ansiedad y de esta manera disminuir el stress que se genera durante la consulta. La inversión inicial será de S/. 190,000.00 (Ciento Noventa Mil con 00/100 Nuevos Soles), siendo la principal inversión la compra de equipos y los gastos iniciales de la operatividad del negocio que llega a un monto de S/. 98,552.00. Debido a que es una empresa nueva y no cuenta con líneas de crédito, inicialmente los accionistas asumirán el 100% del financiamiento, sin embargo al tercer año ya podrán recuperar una parte de su inversión. De acuerdo al flujo de caja realizado y a los supuestos establecidos, como resultados financieros se estima un Valor Actual Neto (VAN) de S/. 158 (Ciento cincuenta y ocho soles), un Costo de Oportunidad de 32.5% y una Tasa Interna de Retorno (TIR) de 51%, lo cual es bastante atractivo considerando el riesgo del negocio y las rentabilidades de negocios similares tales como clínicas dentales, laboratorios de análisis médicos, etc. Incluso la inversión inicial tiene un monto menor frente a negocios similares.Tesis

Thesis submitted to the University of Manchester by Richard Macey for the Degree of Doctor of Philosophy entitled “Detection of Common Dental Diseases by Dental Hygiene-Therapists”, February 2016.Many adult patients that attend NHS dental practices on a regular basis are asymptomatic and do not need any further treatment other than a routine dental examination (“check-up”). As the oral health of the adult population is predicted to improve further, using the General Dental Practitioner to undertake the “check-up” on regular “low risk” patients represents a substantial and potentially unnecessary cost for state-funded systems. Given recent regulatory changes in the United Kingdom, it is now possible to delegate a range of tasks to Dental Hygiene-Therapists, including the routine clinical examination. This has the potential to release General Dental Practitioner’s time and increase the capacity to care at a practice level. The aim of this thesis was to determine the diagnostic test accuracy of Dental Hygiene-Therapists when detecting dental disease, explore the social acceptability of using Dental Hygiene-Therapists to manage “low risk” patients in practice and the feasibility of conducting a definitive trial. A mixed-methods approach was utilised with four inter-linked studies: 1. A diagnostic test accuracy study, which assessed the efficacy of Dental Hygiene-Therapists to detect dental caries and periodontal disease in a primary care setting (n=1899); 2. A comparative accuracy study, which investigated the ability of different dental professional groups to distinguish between photographs of malignant and non-malignant lesions (n=192); 3. A feasibility study, which examined the recruitment, retention and fidelity of using Dental Hygiene-Therapists to manage “low-risk” patients in practice over a twelve month period (n=60); and 4. A series of semi-structured interviews to determine the social acceptability of the use of Dental-Hygiene-Therapists in this role. A fifth study ran in parallel and involved undertaking a Cochrane Diagnostic Test Accuracy Systematic Review. This review informed the methods and conduct of the diagnostic test accuracy studies (studies 1 and 2). When compared to General Dental Practitioners (reference test) the Dental Hygiene-Therapists (index test) produced summary sensitivity and specificity points of 0.81 and 0.87 for dental caries, and 0.89 and 0.75 for periodontal disease respectively. When differentiating between malignant and non-malignant lesions, the Dental Hygiene-Therapist group were comparable to General Dental Practitioners for sensitivity (0.81 versus 0.77 respectively) and for specificity (0.73 versus 0.69 respectively). The feasibility results identified an acceptable recruitment rate of 34%, a retention rate of 63.33% and fidelity of 94.74%. The qualitative interviews found high social acceptability to the idea of using Dental Hygiene-Therapists to undertake routine dental examinations. These results suggest that Dental Hygiene-Therapists could be used to play a more substantial role in the management of “low risk” asymptomatic NHS patients in a primary dental care environment.

Texto completoResumen
El propósito de este estudio fue evaluar la influencia del grabado ácido previo a la aplicación de cuatros sistemas autograbantes, Adper Easy Bond (AEB), Futurabond DC (F), Go! (G) y OneCoat Self Etching Bond (OC), sobre esmalte dental de bovino.
Se utilizaron 24 dientes anteriores de bovino, los cuales fueron colocados en bloques de resina acrílica de 1.5 cm x 1.5 cm, dejándose expuesta la cara vestibular la cual fue posteriormente desgastada ligeramente y pulida. Las piezas dentales fueron dividas en dos grupos experimentales y un grupo control, al primer grupo experimental se le aplicó el sistema adhesivo autograbante según las indicaciones del fabricante, mientras que al segundo grupo se le realizó grabado con ácido ortofosfórico al 35% previamente, el grupo control fue tratado con un sistema adhesivo convencional de grabado total; finalmente se colocó un bloque de resina compuesta Z350 (3M) utilizando un molde de teflón de 8mm de diámetro x 4 mm de altura. Los dientes se almacenaron durante 24 horas en saliva artificial a 37°C. Se obtuvieron cortes de entre 0.8 y 1.00 mm2 de área transversal, los especímenes obtenidos fueron sometidos a Test de Microtensión a una velocidad de 0.5 mm/min. Para el análisis estadístico se utilizaron las pruebas de Kruskall Wallis (p menor a 0.05) y Mann Whitney.
Los valores de adhesión resultantes en MPa para los grupos experimentales sin grabado ácido fueron: AEB: 14.6 ± 3.8; F: 14.3 ± 8.7; G: 9.5 ± 3.8 y OC: 10.5 ± 6.2; para los grupos con grabado ácido previo fueron: AEB: 24.7 ± 14.2; F: 15.6 ± 4.8; G: 16.2 ± 8.9; OC: 14.9 ± 7.1. El grupo control All Bond 2 obtuvo valores de adhesión de 18.6 ± 7.3 MPa.
Se encontraron diferencias estadísticamente significativas entre los grupos experimentales, mientras que en relación al grupo control, el grupo experimental con grabado ácido previo obtuvo valores similares a este a excepción del sistema AEB el cual obtuvo un valor significativamente mayor.The aim of this study was to evaluate the influence of prior acid etching to application of four self-etching adhesive systems, Adper Easy Bond (AEB), Futurabond DC (F), Go!(G) And OneCoat Self Etching Bond (OC), on bovine enamel. Twenty four bovine lower incisors were used, which were mounted in cold – cure acrylic blocks of 1.5 x 1.5 cm, keeping exposed the buccal enamel surface subsequently abraded and polished. The teeth were divided in two experimental groups and a control group. In the first experimental group the adhesive system was applied following manufactures’ instructions, meanwhile the second experimental group was etched with ortophosphoric acid 35% prior to application of the adhesive. Control group was treated with a conventional total etch system. Finally a composite resin restoration Z350 (3M) was built using a Teflon mold of 8 mm diameter and 4 mm height. The teeth were stored in artificial saliva at 37°C during 24 hours. Specimens between 0.8 and 1.00 mm of cross-sectional area were obtained and stressed in tension at 0.5 mm/min cross-head speed. The statistical analysis was developed using Kruskall Wallis (p less than 0.05) and Mann Whitney tests. The bond strengths in MPa obtained for the experimental groups without prior acid etching were: AEB: 14.6 ± 3.8; F: 14.3 ± 8.7; G: 9.5 ± 3.8 y OC: 10.5 ± 6.2; for the groups with prior acid etching the results were: AEB: 24.7 ± 14.2; F: 15.6 ± 4.8; G: 16.2 ± 8.9; OC: 14.9 ± 7.1. Control Group All Bond 2 obtained bond strengths of 18.6 ± 7.3 MPa. Statistically significant differences of bond strengths values were found between both experimental gropus, the experimental group with prior acid etching obtained similar bond strength values to the control group, except for the AEB adhesive which obtained higher significant values.

Texto completoResumen
A denial student is required to gain practical experience as well as theoretical training at the early stage of their training. In order to restore a decayed tooth, fundamental dental procedures are necessary, including: 1. Identification of caries using a sharp denial probe, where the probe physically is inserted a short distance into the caries to observe properties such as volume; 2. Unhealthy tissues must be removed by drilling operation or probe. 3. Complete the restoration procedure by filling in composite resin such as light cured photopolymer. All of these procedures require a high degree of dexterity. Traditional training involves a real denial patient or human head-like dummy model, which pose several distinctive disadvantages such as safety, examination across students, high maintenance cost as well as the recording and feedback of the procedures. A haptic dental training system provides a viable solution to these challenges. This thesis explores the key process in tooth restoration and the development of a new haptic rendering algorithm. These include the development of the mathematical model to identifying material with a short distance insertion probing and filling operation with resin. It also presents a novel hardware design of a dental training system, which allows a student to perform a haptic drilling operation, with a hand-eye collocated gesture. Large scale evaluation of the system is done and results are presented.

O objetivo deste estudo foi avaliar, in vitro, a influência do refrigerante de limão (Sprite®), do suco à base de soja sabor maçã (Ades®) e do suco de morango (Kapo®), empregadas rotineiramente na alimentação de crianças na microdureza superficial e profunda do esmalte de dentes decíduos em função do tempo de exposição. Foram utilizadas quarenta coroas de incisivos decíduos humanos hígidos, acomodados em bases de acrílico mantendo as superfícies vestibulares expostas. Os conjuntos dente/base de acrílico foram impermeabilizados com esmalte cosmético, deixando exposta uma área de 3 mm de diâmetro na face vestibular, na qual foram realizadas as medidas de microdureza superficial Knoop (50 gf, 10 segundos e 5 endentações). Os espécimes foram divididos aleatoriamente em 4 grupos (n=10), de acordo com as bebidas empregadas (Sprite®, Ades®, Kapo®) e controle (mantidos em saliva artificial). Os ciclos de imersão foram realizados sob agitação, durante 5 minutos, 3 vezes ao dia, com intervalos de 4 horas durante 60 dias. As medidas de microdureza superficial foram realizadas após 7, 15, 30, 45 e 60 dias. Obtidas as medidas superficiais, os espécimes foram cortados no sentido longitudinal, lixados e polidos para a avaliação das medidas de microdureza a 30, 60, 90, 120, 150, 200 e 300?m de profundidade em relação à superfície exposta das bebidas. Os dados da microdureza superficial e profunda foram analisados estatisticamente pelos testes ANOVA e Tukey. Foi realizada a microscopia eletrônica de varredura em 20 coroas de incisivos decíduos humanos hígidos submetidos ao mesmo protocolo de imersão dos espécimes utilizados para a análise de microdureza. Nos resultados da porcentagem de variação de microdureza superficial (%VMS), observou-se que o Sprite® apresentou a maior variação de micro dureza superficial (62,02%), sendo estatisticamente diferente do Kapo®morango (49,05%) do Ades®maçã (40,56%) e da saliva (-11,31%). Houve perda progressiva da microdureza ao longo dos períodos estudados. Os resultados da microdureza em profundidade mostraram que houve diferença estatisticamente significante entre o refrigerante de limão (117,98 KHN), o suco de maçã à base de soja (188,18 KHN) e o suco de morango (157.27 KHN). Apenas na profundidade de 300 ?m é que ocorreu semelhança entre as quatro soluções estudadas. Concluiu-se que todas as bebidas avaliadas alteraram a microdureza do esmalte de dentes decíduos tanto superficialmente quanto em profundidade. A alteração em profundidade foi evidente até 200?m, sendo que o Sprite® alterou o esmalte de maneira mais intensa. Observou-se ainda que a alteração na microdureza do esmalte foi diretamente proporcional ao tempo de exposição a essas bebidas. As soluções deste estudo influenciaram negativamente a dureza do esmalte.The aim of this study was to assess, in vitro, the influence of a lemon soft drink (Sprite®), an apple soya juice (Ades®) and a strawberry juice (Kapo®) routinely utilized in children\'s diet on the superficial and deep microhardness of primary teeth enamel, as a function of the exposure time. Forty crowns of caries-free human primary incisors were included in acrylic bases, keeping the buccal surfaces exposed. The ensembles tooth/acrylic base were rendered waterproof by coating them with cosmetic nail varnish, leaving exposed a 3-mm area on the buccal surface, in which superficial Knoop microhardness measurements were performed (50 gf, 10 sec and 5 indentations). The specimens were randomly assigned to 4 groups (n=10), according to the beverages employed (Sprite®, Ades®, Kapo®) and the control group (kept in artificial saliva). The immersion cycles were performed under agitation for 5 minutes, 3 times a day, with 4 hours intervals, during a 60-day period. The superficial microhardness measurements were done after 7,15,30,45 and 60 days. Once the superficial measurements were performed, the specimens were longitudinally cut, ground and polished for the deep measurements to be accomplished. Microhardness measurements were done at 30, 60, 90, 120, 150, 200 e 300?m deep from the surface exposed to the beverages. Superficial and deep microhardness data were statistically analyzed using ANOVA and Tukey statistical tests. Scanning electron microscopy was performed in 20 crowns of caries-free human primary incisors submitted to the same imersion regimen as that of specimens utilized for microhardness testing. The results of superficial microhardness variation percentage (%VMS) showed that Sprite® (62, 02%) yielded the greatest microhardness, being statistically different from Kapo® (49, 05%); Ades® (40, 56%) and saliva (-11, 31%). There was a gradual and significant microhardness loss on superficial microhardness in all periods evaluated. The results of deep microhardness showed that there was statistically significant difference between the lemon soft drink (117, 98 KHN), apple soya juice (188, 18 KHN) and the strawberry juice (157.27 KHN). There was similarity between the beverages evaluated only at 300 ?m depth. It may be concluded that all beverages evaluated altered both the superficial and the deep microhardness of enamel of primary teeth. The alteration in deep microhardness was evident up to the 200?m depth. Sprite® affected the enamel more aggressively. It was also observed that the alteration on the enamel microhardness was directly proportional to the time of exposure to the beverages. The beverages of the reported study presented a negative impact on the enamel surface and depth of primary teeth.

Texto completoResumen
To improve on the traditional approaches of dental treatment need estimation, a new theoretical model of treatment needs composed of 'Normative', 'Impact-Related', 'Effective' and 'Accessible' treatment needs, is proposed. The aim of the present study was to develop an appropriate socio-dental indicator to generate 'Impact-Related Treatment Need', compare them with traditional professionally assessed normative need, and to explore the preliminary approach to assess 'Effective Treatment Need' for periodontal treatment. An oral health survey was carried out in Ban Phang district, Khon Kaen, Thailand. 501 people aged 35-44 years in 16 villages, selected by cluster random sampling process, were interviewed about oral impacts on daily performances and their oral health behaviours, and then were had clinical examinations. A concise indicator 'Oral Impacts on Daily Performances' (OIDP) was developed, based on measuring impacts on eight physical, psychological and social aspects of daily activities. Scores were calculated by multiplying the frequency by the severity scores of each performance, then scores were summated. The indicator was tested for psychometric properties on the study sample, using interviews and clinical examinations. Cronbach alpha of internal consistency was 0.65. Kappa of test-retest reliability ranged from 0.6 to 1.0. Criterion validity was shown by a strong relationship with general perceptions of oral impacts (p < 0.001). Construct validity was demonstrated by significant differences of scores between groups with high and low prevalence of deep periodontal pockets, decayed and missing teeth, and number of functional teeth (p < 0.001). The combination of specific OIDP scores and normative needs generated the impact-related need for various dental treatments. As expected, the percentage of people with need was decreased from normative need, when Impact-Related Treatment Need was applied. The differences were large in needs for prostheses, orthodontics and periodontal treatment (ranging from 21.7% to 40.2% of normative need); moderate for restorations (64%); and low for pulp care, extractions and treatment for deep periodontal pockets (81.7%-91.7%). A similar pattern of need reduction was obtained when increasing cut-off points of OIDP scores. An exploratory study to develop 'Effective Treatment Need' for periodontal treatment was done. It was shown, using logistic regression that plaque control and smoking were the behaviour-oriented risk factors which affected behavioural propensity for periodontal destruction. Receiver Operating Curve showed the appropriate cut-off point of plaque level at 0.8. Behavioural propensity was determined from people who are non-smokers with plaque index of 0.8 or lower, to generate Effective Treatment Need. The results indicated that the majority of people who had Impact-Related Treatment Need for periodontal treatment did not have the acceptable level of behavioural propensity required for effectiveness of treatment. The advantages of the socio-dental needs approach in dental care planning were demonstrated and discussed. It was concluded that the OIDP is a valid and reliable indicator of oral outcomes. Integrating it into Impact-Related Treatment Need, as well as further integration of behavioural propensity to generate Effective Treatment Need could provide alternative improved dental treatment need estimations.

Texto completoResumen
Dental erosion has increased in prevalence over the last decades. The wider availability and frequent consumption of acidic soft drinks and other acidic substances is thought to be one of the main aetiological factors. It is also well established that this frequent exposure of dental hard tissue surfaces to such acidic attacks renders the outermost enamel layer softened and readily susceptible to be rubbed away by mechanical forces. While most of the studies emphasised on the role of toothbrushing, the effect of oral musculature, especially the tongue, is considered to play a major part in abrading pre - eroded enamel surfaces. Despite the attempts to in vitro simulate tongue abrasion; there is a lack in the literature regarding its role as a causative factor in tooth surface loss. The work presented in this thesis is divided into six chapters. The first chapter includes a general review on tooth wear, enamel erosion and abrasion in particular, referring to the various techniques commonly used to quantify enamel mineral and surface loss. Chapter 2 investigates the erosive effect of some commercially available alcoholic beverages (alcopops) on enamel surfaces. The results from that study showed that alcopops have a significant potential to cause erosion similar to that of orange juice. Further, in the same chapter, a group of dental materials commonly used to mount tooth specimens in erosion studies were examined for their fluorescence properties. It was found that some of those materials exhibited fluorescence activity that affected the quality of images using equipments such as quantitative light - induced fluorescence. Chapter 3 demonstrates that the application of tooth whitening products is not without risking enamel surfaces to undergo erosion and that chlorine dioxide bleaching products, although to a lesser extent, can cause surface demineralisation similar to that caused by hydrogen peroxide. In chapter 4, the effect of simulated tongue abrasion on pre - eroded enamel surfaces is investigated over different periods of erosion and abrasion cycles. Results from that study revealed a significant amount of mineral and surface loss after the application of tongue simulated movements particularly when erosion times were prolonged. Chapter 5 describes an in vitro study where the super saturation of artificial saliva with calcium ions has greater remineralisation properties than the specially formulated Pronamel® mouth wash, deionised water and modified artificial saliva without calcium. The mouthwash has superior remineralisation effect while the two latter solutions, particularly the modified artificial saliva without calcium, caused the greatest mineral loss and lesion depth. Chapter 6 embraces two studies; an in situ part investigating the effect of tongue abrasion on pre - eroded enamel surfaces in addition to an in vitro pilot study investigating the period required for those eroded surfaces to be physically lost to form craters. The findings from the in situ study shows that short and cyclic exposure of enamel specimens to acidic drinks followed by mechanical abrasion by the tongue results in an increased mineral and surface loss. This effect was more recognised on specimens localised opposite to the upper anterior teeth. Also, labial and palatal enamel surfaces have similar mineral and surface loss. Enamel craters formed after as early as 1 week and showed a significant depth after 4 weeks of exposure to orange juice. In conclusion, it has been shown that the tongue could exert an amount of pressure sufficient to remove pre - eroded enamel surfaces.

Texto completoResumen
Although the population of adults age 65 and older with Alzheimer’s disease and other dementias is growing exponentially, many dental professionals are not adequately prepared to work with these special needs patients in the clinical setting. The purpose of this project was to develop a training for dental professionals including basics about dementia, and communication and behavioral management. Personal oral hygiene, often lacking in a person with dementia, contributes to periodontal inflammation and oral infection that may be linked to potentially, life-threatening diseases, including cardiovascular disease, and aspiration pneumonia. This could result in poor quality of life, and hospital or nursing home admission. The training will help dental professionals to better provide preventive or maintenance dental care or assist in providing care. The training will meet a portion of the continuing education biennial course requirements and course provider requirements for license renewal of dental professionals in California. The training was presented to dental professionals. Their feedback, as well as suggestions from an expert panel, informed revisions to the training, such as increasing the length of the training and including “brain breaks” in the presentation.

Texto completoResumen
Trabajo de Investigación Requisito para optar al Título de Cirujano DentistaIntroducción: Las estéticas facial y dental son parte importante del atractivo físico. Sentirse insatisfecho con la apariencia física puede tener repercusiones no solo estéticas, sino también sociales y psicológicas. Muchos pacientes están insatisfechos con el color de sus dientes. El propósito de este estudio fue evaluar el impacto psicosocial de la estética dental en pacientes sometidos a blanqueamiento dental. Materiales y métodos: Fueron evaluadas 31 personas mayores de 18 años, de ambos sexos, que acudieron a la clínica de la FOUCH, las que fueron sometidas a blanqueamiento dental. A cada sujeto, después de la firma del consentimiento informado, se aplicó el cuestionario PIDAQ para medir el impacto psicosocial de la estética dental en 3 momentos (previo al blanqueamiento dental, a la semana posterior al tratamiento y al mes). Los sujetos fueron contactados vía telefónica y se citaron para la aplicación del cuestionario por escrito. Resultados: Existe una diferencia estadísticamente significativa entre la medición del impacto psicosocial de estética dental previo al blanqueamiento versus la evaluación post-blanqueamiento (p=0,019). Sin embargo, no se observan diferencias estadísticamente significativas entre la evaluación pre blanqueamiento y la evaluación al mes (p=0,217) ni entre la evaluación post blanqueamiento y el mes (p=1,000). Con respecto a las dimensiones del cuestionario, se observan cambios significativos en autoconfianza, impacto social e impacto psicológico. No existe diferencia estadísticamente significativa en preocupación estética. Conclusiones: Los aspectos psicosociales del paciente se ven modificados positivamente en pacientes sometidos a blanqueamiento dental. El impacto psicológico tiene un cambio positivo solo al realizar la comparación entre la evaluación pre y post blanqueamiento. La autoconfianza e impacto psicológico presentan un cambio positivo que se mantiene en el tiempo. El blanqueamiento no tiene efectos significativos en la preocupación estética.

Este estudo in vitro avaliou o efeito da abrasão do esmalte humano na rugosidade superficial e na alteração de cor de dentes previamente submetidos à erosão. Quarenta e oito pré-molares humanos hígidos foram divididos em face vestibular e lingual, totalizando 96 fragmentos. Os espécimes foram divididos em quatro grupos (n=24): C - controle; O - clareamento com peróxido de hidrogênio a 38% (Opalescence Xtra Boost); OR - clareamento e imersão em refrigerante a base de cola (Coca-cola); R - imersão em refrigerante. Cada grupo foi dividido em dois subgrupos, para escovação com dentifrício de abrasividade regular (DR) e dentifrício branqueador (DB), em máquina simuladora de escovação. Antes e após o tratamento preconizado para cada grupo, a rugosidade foi mensurada em um rugosímetro (SJ-400, Mitutoyo) e a aferição da cor por meio de um espectofotômetro (Easyshade, Vita). Os dados foram submetidos à ANOVA e testes de Dunnett e Tukey. O grupo OR apresentou o maior aumento de rugosidade (0,092), que foi estatisticamente semelhante ao grupo O (0,046) e diferente da diminuição causada por R (-0,007). Quanto à alteração de cor, OR apresentou valores intermediários (7,95), sendo estatisticamente semelhante tanto ao grupo O (9,96) quanto ao R (6,37), que diferiram entre eles. Concluiu-se que a exposição do esmalte tanto ao gel clareador como à coca-cola não aumentou a rugosidade e que a exposição à coca-cola durante o tratamento clareador não ocasionou descoloração dental. Os dentifrícios regular e branqueador apresentaram desempenho de rugosidade e de alteração de cor estatisticamente semelhantes em todos os grupos avaliados.
This in vitro study aimed to evaluate the effect of human enamel abrasion on the surface roughness and color change of teeth previously submitted to erosion. Forty eight intact human pre-molars were divided in buccal and lingual faces, adding up to 96 fragments. The specimens were divided into four groups (n=24): C – control; O – bleaching with 38% hydrogen peroxide (Opalescence Xtra Boost); OB – bleaching and immersion in cola beverage; B – immersion in cola beverage. Each group was further divided into two subgroups, for brushing with regular abrasiveness dentifrice (RD) and whitening dentifrice (WT), in a toothbrushing machine. Before and after the treatment proposed for each group, roughness was measured in a profilometer (SJ-400, Mitutoyo) and colour evaluation was performed with a spectrophotometer (Easyshade, Vita). Data was submitted to ANOVA and Dunnett and Tukey tests. Group OB presented the highest roughness increase (0.092), which was statistically similar to group O (0.046) and different from the decrease caused by B (-0.007). Regarding colour change, OB presented intermediary values (7.95), which were statistically similar to group O (9.96) and B (6.37), which were different between them. It was concluded that exposure of enamel to bleaching gel or cola beverage did not increase roughness and exposure to cola soft drink during bleaching treatment did not cause dental discolouration. Regular and whitening dentifrices presented similar performance regarding surface roughness and colour change in all evaluated groups.

Thank you.Restorative dentistry restores the function of the teeth and their surrounding structures. Patients may need dental restorative procedures due to disease, trauma, and esthetics purposes. The most prevalent dental disease is caries, which is treated by the removal of bacteria and the placement of a restorative material. This thesis aims to determine if the use of amalgam restoration should be discontinued in the United States. To determine if dental amalgam restorations should be discontinued the safety and of amalgam, composite, and ceramic materials will be evaluated. The objective is to review the current literature to determine if the use of amalgam is unethical and if composite and ceramic restorations can serve as a proper alternative. Restorative materials have been used for over 170 years and the contents in these materials have been very controversial. The first record of amalgam placement was in 659 AD in China through Material Medica. Since then, new advancements and different compositions have varied to increase the efficacy of amalgam restorations. Composite restorations became popular in the early 1960's and have drastically improved and are now comparable in compressible strength to amalgam restorations and are placed in posterior teeth. Porcelain, ceramics has been used in dentistry since the 1800's and has advanced through fabrication and cementation techniques. One fabrication technique of interest is the utilization of CEREC CAD/CAM systems. This system has also evolved and is now on its third generation; its original design included fabricated inlays and onlays only. Now, The CAD/CAM has evolved to fabricate inlays, onlays, crowns, and veneers. The use of dental amalgam has been shown through many studies to be safe and has an unmatched longevity record. Composites and porcelain ceramics are also successful to varying degree but do not have the longevity found with amalgam. These studies, demonstrates the use of amalgam in the United States is ethical, successful, cost effective, and should not be discontinued.

El gasto actual en Chile destinado a la salud bucal ha crecido en forma importante en los últimos años pero aún en comparación a los países OECD es considerablemente bajo, por lo que existe un enorme potencial en la industria odontológica si Chile se acerca a los niveles que tienen actualmente los países OECD, a modo de ejemplo hoy el promedio de visitas al odontólogo en Chile es de 0,69 veces al año versus el promedio de los países OECD que es de 1,38 veces al año, lo que significaría pasar en términos de visitas a prácticamente el doble.

Introduktion: I Tanzania lever mer än var femte innevånare i fattigdom och endast hälften har tillgång till rent vatten. Den orala hälsan tas sällan om hand på rätt sätt och behovet av orala hälsoprogram är stort. Landet har också problem med höga fluorhalter i grundvattnen vilket har förödande konsekvenser för tänderna. Syfte: Att studera förekomsten av dental karies och dental fluoros samt vilka munvårdsvanor barn 6-18 år har i Tanzania Frågeställningar: Vilken är förekomsten av dental karies bland barn 6-18 år i Tanzania? Vilken är förekomsten av dental fluoros bland barn 6-18 år i Tanzania? Vilka munvårdsvanor har barn 6-18 år i Tanzania? Metod: En litteraturstudie Resultat: Studierna visade att kariesförekomsten i de studerade åldersgrupperna var låg. Vanligast med karies i det permanenta bettet är i djupa fissurer och andra molaren i underkäken. En ökad risk för dental fluoros genom intag av magadi och ökad fluorhalt i dricksvattnet. Dental fluoros ökar risken för ett nedsatt välbefinnande. En studie (2010) visar även på att tandborstningsfrekvensen och användning av tandkräm är mer frekvent än förr (1994, 1998). Besök hos tandläkaren sker inte kontinuerligt. Konklusion: Litteraturstudien visade på ett omfattande behov av munhälsoprogram i Tanzania samt olika åtgärder mot dental fluoros.

Texto completoResumen
The traditional normative approach to dental needs assessment has serious shortcomings. Studies aiming to improve the normative approach are limited to adults, and cover particular types of dental treatment. The objective of this study was to develop a comprehensive system of dental needs assessment in children using the socio-dental approach, and to compare it with the traditional normative approach. It was hypothesised that the proportion of socio-dentally assessed needs was significantly lower than that assessed normatively. All 1126 grade-6 primary schoolchildren aged 11-12 years in Suphanburi province in Thailand were invited and 1034 participated in a cross-sectional survey. They were dentally examined for normative treatment needs, interviewed to assess oral impacts and completed a self-administered questionnaire on demographic and behavioural data. The integration of oral impacts with Normative Needs generated Impact-Related Needs, while further considering oral behaviours and evidence-based treatment resulted in Propensity-Related Needs. The CHILD-Oral Impacts on Daily Performances (CHILD-OIDP) index was developed to assess oral impacts. The index was shown to be a valid, reliable and practical measure of oral health-related quality of life in 12-year-old Thai children. It has potential to be integrated into the socio-dental needs system. When the socio-dental approach was used to assess needs, there was a large reduction in the extent of needs, when compared to the normative approach. The prevalence of needs for treatment/care for non-progressive dental conditions decreased from 98.8% for Normative Needs to 39.5% for Impact-Related Needs (p 0.001). The amount of normative treatment required decreased further when Propensity-Related Needs were assessed. It is concluded that the socio-dental needs assessment approach decreases the amount of dental needs. The approach highlights not only the importance of oral health-related quality of life in needs assessment, but also incorporates a broader approach for dental care in meeting children's dental needs.

Texto completoResumen
This work introduces a series of papers developed to explore the case for change in dental education. Three issues facing dental education are (a) the challenging financial environment of higher education, making dental schools very expensive and tuition-intensive for universities to operate and producing high debt levels for students, which limits access to education and restricts career choices; (b) the profession's apparent loss of vision for taking care of the oral health needs of all components of society and the resultant potential for marginalization of dentistry as a specialized health care service available only to the affluent; and (c) the nature of dental school education itself, which has been described as convoluted, expensive, and often deeply dissatisfying to its students. The theoretical rational for this work is that developing dental faculty from solely clinicians to academicians will allow for the curricular change so needed in dental education. Furthermore, it is curricular change that can lead to changes in the oral health profession.My work first explores the scientific nature of research into dental education to determine its ability to advance the profession. This study found that while there has been a small increase in the amount of rigorous dental education research in the past 10 years, it remains a small percentage of the overall research completed in the field. We then researched the effect of pedagogical training for dental clinicians and discovered predictors for those faculty members more likely to alter their methods to be more student centered. Our narrative research into faculty resistors (those unwilling to change) allowed us to identify themes that can alter our approach to future faculty development. And finally, we researched the effect of modern pedagogy on a course in the dental school curriculum. This research allowed us to justify curricular changes that improve efficiency and student performance.

The purpose of this study was to examine the use of dental services for young children following a preventive oral health intervention in a pediatric medical clinic. Over a 3 year period (2005-2008), children 0-36 months of age, enrolled in Medicaid, were provided preventive oral health services in a medical setting. Descriptive statistics and multivariate logistic regression were used to determine the effect receiving the preventive oral health services in a medical setting with the outcomes of dental utilization. 15% were determined to have dental caries at the intervention and 42% found to have a dental visit post-intervention. Children determined to have decay at the intervention were significantly more likely to have one or more restorative or adjunctive service post-intervention. After receiving preventive oral health care in a medical clinic, the resulting utilization of dental services was higher than what is commonly reported for dental utilization in infant populations of low-income children.

Magister Scientiae Dentium - MSc(Dent)Introduction: Dental fluorosis is a developmental disturbance of enamel that results from ingestion of high amounts of fluoride during tooth mineralization. Drinking water remains the main source of fluoride. Other sources of fluoride include infant formula, vegetables; canned fish as well as early, improper utilization of fluoridated toothpastes in children. Knowledge of risk factors in the causation of dental fluorosis may improve strategies to prevent dental fluorosis. Objective: To determine the prevalence of dental fluorosis among children aged 12-15 years old in Athi River sub-county, Machakos County, Kenya and assesses the level of knowledge on risk factors for dental fluorosis among their parents. Methodology: This was a descriptive study with an analytic component. A total of 281 children aged 12-15 years attending public primary schools within Athi River sub-county, Machakos County were included. A self-administered questionnaire was send to parents for socio-demographic characteristics and oral health practices. Children whose parents consented were examined and dental fluorosis scored according to the Thylstrup and Fejerskov index. Fourty randomly selected children were requested to bring water samples from their homes. Retail stores located in the area were visited for purchase of six different brands of bottled water. These samples were sent to a certified laboratory for fluoride analysis and reported in milligrams of fluoride per litre. Data analysis: Data was entered into SPSS version 20 and analysed for means, ANOVA of means and chi-square test of significance for categorical variables. All tests for significance were set at 95% confidence level (α≤0.05). Results: A total of 314 self-administered questionnaires were send to parents together with consent forms for their children‟s participation in the study. Two hundred and eighty six responded positively, giving a response rate of 91%. The overall prevalence of dental fluorosis among children aged 12-15 years was 93.4% with only 6.6% (n=19) recording a TFI score of 0. About one quarter 70(24.4%) of children had severe fluorosis with TFI scores of ≥5. The mean TFI score for all children was 3.09 (SD=2.0), with males recording a mean TF score of 3.01 (SD=2.11) and females a mean TF score of 3.16 (SD=1.88). Out of 44 water samples analysed, 29 (65.9%) had a fluoride content of less than 0.6mg/l, 5 (11.4%) had fluoride content of 0.7 - 1.5mg/l while 10 (22.7%) of samples had a fluoride content ≥1.5mg/l. The highest fluoride content recorded was 9.3mg/l, with another sample reflecting 8.9mgF/l. Three of the bottled water samples had a fluoride content of less than 0.6mg/l, while the other half of the bottled water reported 0.7 - 0.8mg/l fluoride. A majority (87.8%) of parents indicated that they had noticed children with brown staining of their permanent teeth in their community. About 80% of parents thought dental fluorosis was caused by salty water, while only 12.9% correctly identified water with high fluoride content as being responsible for the discolored teeth. Conclusion: Although about one in five water sources sampled had fluoride content of ≥1.5mg/l, the prevalence of dental fluorosis in this community was very high. Parental knowledge on the risk factors for dental fluorosis was low. Further research is necessary to identify the water distribution networks to provide sound evidence for engaging with the county authorities on provision of safe drinking water to the community.

Texto completoResumen
The purpose of this study was to explore the experience of parents whose young children
had had a general anesthetic (GA) for dental treatment and to develop a model to describe
and explain parental behaviour change following the GA experience. A grounded theory
method was undertaken to investigate 1) parent's beliefs and behaviours that may place
their child at risk to new caries following the GA experience, 2) parents' experience of
their child's dental treatment under GA and 3) the factors affecting parental adoption and
maintenance of dentally healthy behaviours.
Twenty-six in-depth individual interviews were conducted with parents of pre-school aged
children at various times after the GA, i.e. shortly after the GA and up to one year
following the GA. Data were analysed with a grounded theory approach, to develop a
model that was "grounded" in the data.
A conceptual model was generated to explain the process of parental behaviour change.
Social influences, family context, and parental strategies were identified as key categories.
Cultural beliefs, actions of dental professionals, and media/advertising were barriers for
parents to adopt healthy behaviours. Not all parents were receptive to social supports;
cross-cultural differences were apparent. Overall, the GA dental experience had enough
of an impact to immediately motivate parents to consider changing their behaviours.
However, difficulty and only partial compliance in following recommendations were
frequently mentioned.
Although parental stretiges were influenceed by family context and social influences, the
central position of parental strateiges in the model gradually emerged. Parents who took responsibility for their child's state of health felt guilt and were determined to develop
strategies to overcome the barriers in applying healthy behaviours. Parents who had a high
level of self-efficacy and were furthest along the stages of change continuum were likely
able to engage in and maintain new healthy behaviours.
Although an early, positive outcome of the GA was a reported improvement in dental
health practices, the GA did not appear to affect long-term preventive behaviours for
many parents. Parental strategies were recognized as the core category of the final model
that influenced whether parents adopted dentally-healthy behaviours and maintained these
behaviours over time.Dentistry, Faculty of

Oral diseases including dental caries and periodontal disease are among the most prevalent and costly diseases in Australia today. Around 5.4% of Australias health dollar is spent on dental services totalling around $2.6 billion, 84% of which are delivered through the private sector (AIHW 2001). The other 16% is spent providing public sector services in varied and inadequate ways. While disease rates among school children have declined significantly in the past 20 years the gains made among children are not flowing on to adult dentitions and our aging population will place increasing demands on an inadequate system into the future (AHMAC 2001). Around 50% of adults do not received regular care and this has implications for widening health inequalities as the greatest burden falls on lower income groups (AIHW DSRU 2001).
The National Competition Policy agenda has initiated, Australia-wide, reviews of dental legislation applying to delivery of services by dentists, dental specialists, dental therapists and hygienists and dental technicians and prosthetists. The review of the Victorian Dentists Act 1972, was completed first in 1999, followed by the other Australian states with Queensland, the ACT and the Northern Territory still developing legislation. One of the objectives of the new Victorian Act is to
promote access to dental care. This study has grown out of the need to know more about how dental therapists and hygienists might be utilised to achieve this and the legislative frameworks that could enable such roles.
This study used qualitative methods to explore dental health policy making associated with strategies that may increase access to dental care using dental therapists and hygienists. The study used a multiple case study design to critically examine the dental policy development process around the Review of the Dentists Act 1972 in Victoria; to assess legislative and regulatory dental policy reforms in other states in Australia and to conduct a comparative analysis of dental health policy as it relates to dental auxiliary practice internationally.
Data collection has involved (I) semi-structured interviews with key participants and stakeholders in the policy development processes in Victoria, interstate and overseas, and (ii) analysis of documentary data sources. The study has taken a grounded theory approach whereby theoretical issues that emerged from the Victorian case study were further developed and challenged in the subsequent interstate and international case studies. A component of this study has required the development of indicators in regulatory models for dental hygienists and therapists that will increase access to dental care for the community. These indicators have been used to analyse regulation reform and the likely impacts in each setting.
Despite evidence of need, evidence of the effectiveness and efficiency of dental therapists and hygienists, and the National Competition Policy agenda of increasing efficiency, the legislation reviews have mostly produces only minor changes. Results show that almost all Australian states have regulated dental therapists and hygienists in more prescriptive ways than they do dentists.
The study has found that dental policy making is still dominated by the views of private practice dentists under elitist models that largely protect dentist authority, autonomy and sovereignty. The influence of dentist professional dominance has meant that governments have been reluctant to make sweeping changes. The study has demonstrated alternative models of regulation for dental therapists and hygienists, which would allow wider utilisation of their skills, more effective use of public sector funding, increased access to services and a grater focus on preventive care. In the light of theses outcomes, there is a need to continue to advocate for changes that will increase the public health focus of oral health care.

Texto completoResumen
The World Health report 2000 notes that determining the "right" mix of health personnel are major challenges for most health care organisations and health systems. Health care is labour-intensive and providers continually strive to identify the most effective mix of staff that can be achieved with the available resources taking into account local priorities. These issues are as much as a challenge in dentistry as in other parts of the health care system. For decades the dental team has included a range of different types of personnel that can deliver dental care. Although not all countries include dental therapists (DTs) in the team, in England DTs play an important role and have been able to work in dental practice for many years, with recent years showing an expansion in the number of DTs in the UK. Nevertheless such policies put in place to support a widening of skill mix in dental practice have not been met with a widespread change in the format of dental teams. A great number of UK dual-qualified DTs practise mostly as dental hygienists. Whilst dental practitioners have previously expressed generally favourable attitudes towards the employment of dental therapists, DTs are perceived as having limited financial value to dental practices. Thus there appears to be a gap between the implementation of a skill-mix policy in principle and the actual employment and use of DTs in dental teams. The aim of this study is to explore this area and identify ways in which dental therapists could be . effectively used in UK dental practices. This study used a multiple case study design with both qualitative and quantitative methods of data collection. Semi-structured interviews were carried out with 48 principal dentists, associate dentists, DTs, practice managers and dental hygienists. Non-participant observation was undertaken on the location of the practices, the type of buildings and any phenomena that the researcher thought might contribute to the case studies. A day sheet proforma was used to collect clinical production data. A la-item scale of patient satisfaction (Dental Visit Satisfaction Scale [DVSS]), which provides an outcome measure of overall patient satisfaction as well as three sub-scale outcomes (information- communication; understanding-acceptance; technical competence) was used. Dental practice sites were described as case studies. Interview transcripts were analysed using a Grounded Theory (GT) approach to identify categories and sub-categories. The quantitative data was analysed using statistical methods including t-tests and regression analysis. Drawing upon the findings from multiple sources, this study identifies an effective model of using DTs and offers a theory of factors influencing whether DTs can be successfully used in dental practice teams. Findings show that it is possible to overcome the apparent disincentives to DT delegation embedded within the UDA remuneration system by changing reimbursement arrangements within the practice. In addition, the prevalent management ethos in the dental practices was one geared towards assessing success according to a cost-volume-profit business model, where this was measured on the individuals' contributions rather than on the performance of the team as a whole. A fundamental shift is needed in order for DTs to be fully integrated into dental practice teams. A total number of five categories with seventeen sub-categories have been developed from GT analysis. "Striving for efficiency" emerged as the core category. Since dental practices are complex organisations, their goals may vary and hence the views of using DTs may well be different. The theory presented in this study suggests significant implications for policy and dental practices. Recommendations were as follows: Policy reforming the remuneration system should take account of practitioners' requirement to make the contribution of team members measureable. Teamwork should be integrated into undergraduate and postgraduate education as well as in-practice training. New organisational forms or a shift in practitioner worldviews regarding team-working are needed in order for DTs to be fully integrated into dental practice teams. The strategy for effectively using DTs in dental practice teams may be limited to particular situations where conditions are conducive to such use.
