Orthodontic treatment may cause an increase in the rate of enamel decalcification on tooth surfaces, producing White Spot Lesions (WSL). Orthodontic patients are at a higher risk for decalcification because orthodontic appliances retain food debris which leads to increased plaque formation. Dental plaque, an oral biofilm formed by factors including genetics, diet, hygiene, and environment, contains acid producing bacterial strains with a predominance of Mutans Streptococcus (MS). MS and others metabolize oral carbohydrates during ingestion, the byproducts of which acidify the biofilm to begin a process of enamel decalcification and formation of WSL. This study tests if patients in orthodontic treatment at Temple University can be used as subjects for further longitudinal study of WSL risk factors. Twenty patients between the ages of ten to eighteen after three months or greater of treatment were enrolled to determine if duration of treatment, hygiene, sense of coherence, obesity, diet frequencies, age and gender correlated with development of WSL. Of these, age is positively correlated with the number of untreated decayed surfaces. WSL and plaque levels may negatively correlate with increased brushing frequency and duration, while flossing frequency demonstrated a statistically significant negative correlation. This population may be suitable for further study because of its high incidence of WSL (75%), however difficulty in enrollment and patient attrition necessitates that future studies be modified.

White Spot lesions are a common iatrogenic occurrence on patients who are treated with fixed orthodontic appliances. There is a dynamic chemical interaction between enamel and saliva at the tooth surface that allow a lesion to have phase changes involving demineralization of enamel and remineralization. This is due to calcium and phosphate dissolved in saliva that is deposited onto the tooth surface or removed depending on the surrounding pH. Caseinphosphopeptide-amorphous calcium phosphate (CPP-ACP) is gaining popularity in dentistry as a way to increase the available level of calcium and phosphate in plaque and saliva to improve the chemical gradient so that if favors remineralization. The aim of our investigation is to search the available current literature and formulate a recommendation for use of CPP-ACP in orthodontics. Publications from the following electronic databases were searched: PubMed, Web of Science, Cochrane Library and Science Direct. Searches from August 2010 to April 1st 2012 were performed under the terms "MI Paste OR Recaldent OR caseinphosphopeptide-amorphous calcium phosphate OR CPP-ACP or tooth mousse". The searches yielded 155 articles, These were reviewed for relevance based on inclusion and exclusion criteria. Articles with inappropriate study design or no outcome measures at both baseline and end point were also excluded. 13 articles were deemed of relevance with a high quality study design and were included in this study for evaluation. The current literature suggests a preventative treatment regimen in which MI Paste Plus is used. It should be delivered once daily prior to bed after oral hygiene for 3 minutes in a fluoride tray, throughout orthodontic treatment. It should be recommended for high risk patients determined by poor oral hygiene, as seen by the inability to remove plaque from teeth and appliances. This protocol may prevent or assist in the remineralization of enamel white spot lesions during and after orthodontic treatment.

Fixed orthodontic appliances harbor plaque and perpetuate the formation of early non-cavitated carious lesions. However, not all patients with poor hygiene develop them. It has been established that fluoride varnish can be used to promote enamel remineralization. The study aimed to assess the efficacy of fluoride varnish in remineralizing early non-cavitated lesions among orthodontic patients. A second goal of this study was to elucidate if BMI and obesity increased susceptibility to development of white spot lesions. A randomized control trial was conducted among 25 patients attending the Orthodontic clinic at Temple University. Patients were ages 11-18 and had fixed orthodontic appliances for a minimum of three months. Eleven were randomly assigned to a test group (Enamel Pro® Varnish fluoride varnish application to white spot lesions every two months) and 14 randomly assigned to a control group (reinforcement of oral hygiene instructions). Data collection was completed every two months over a six-month time period. White spot lesion size was measured using the International Caries Detection and Assessment System (ICDAS). Oral hygiene was assessed using Plaque Index (PI) and S. mutans levels were measured using Stripmutans plaque/salivary tests (Dentocult®). Both the control and experimental group had non-significant decreases in non-cavitated carious lesion count. The control group displayed significant increases in Stripmutans salivary scores (p0.05). PI scores decreased in the control group and increased in the experimental group (p>0.05). There was no correlation between BMI and lesion count in the control or experimental group (p>0.05). A 5% sodium fluoride varnish containing Amorphous Calcium Phosphate (Enamel Pro® Varnish) fluoride varnish application was not efficacious in reducing early non-cavitated carious lesions when compared to reinforcing oral hygiene. There is no correlation with BMI and white spot susceptibility.

Повний текст джерелаWhite spot lesion is the subsurface hypomineralization of enamel indicating the 1st stage of dental caries development. Early detection of incipient dental caries before it reaches the stage of cavitation offers an opportunity for effective dental care. The objectives of this study were to strengthen the idiom of minimally invasive treatment. In order to achieve the specified goals; we have identified a modified pH cycling model that can mimic the intraoral conditions leading to white spot lesions formation in a short time. In addition, non-invasive optical techniques, such as confocal Raman microscopy and multiphoton microscopy were used in this study to detect small changes in the enamel chemical composition in vitro.Furthermore, nano-indentation technique was used to detect the changes in the mechanical properties of enamel and relate them to those affecting its chemical composition after caries induction in order to add chemico-mechanical specificity in providing important information about subsurface lesions in enamel. The obtained results demonstrate a great potential for the examined techniques, providing a basis for interesting applications in the clinical diagnosis of various pathological conditions in dentistry. To treatment the incipient carious lesions non-invasively, the effectiveness of GC Tooth Mousse cream and nHA containing-dentifrice "KAREX" in the remineralization of demineralized enamel through localizing amorphous calcium phosphate at tooth surface has been inspected. The study indicated a lack of reliable evidence supporting the efficacy of remineralizing agents in the treatment of white spot lesions. Within the limitations of this study, further laboratory studies together with clinical research are therefore required to increase the available knowledge on this prevalent subject

To examine by Scanning Electron Microscope (SEM) the effect of these drinks on intact and sealed enamel. Methods: 120 brackets were bonded to bovine incisors and divided into: 1)Control-group; 2)Coca-Cola®; 3)Schweppes®-Limón. The teeth were submerged in the drinks 3 times/day (15 minutes) during fifteen days. Shear bond strength was measured with a universal test machine, and adhesive remnant using image analysis equipment. Microleakage at the enamel-adhesive and adhesive-bracket interfaces was detected using methylene blue. 108 teeth were used to examine by SEM the effect of the drinks on intact and sealed enamel. Results: No significant differences were found in bond strength and adhesive remnant between groups. Microleakage at the enamel-adhesive interface for Coca-Cola® and Schweppes®-Limón was significantly greater than for the control. At the adhesive-bracket interface microleakage was significantly greater with Coca-Cola® than with the control whilst microleakage with Schweppes®-Limón did not differ significantly from either Coca-Cola® or the control. The drinks produced enamel erosion and loss of adhesive.

Повний текст джерелаThe objective of this clinical study was to evaluate the effectiveness of the toothbrushing with and without fluoride and the daily fluoride rinse (NaF 0.05%) on produced white spot, in vivo. This was a clinical study, controlled, randomized and triple blind. Thirty patients were selected for orthodontics reasons from Orthodontics Specialization Course at the Brazilian Dental Association - Section of Rio Grande do Norte. In this study it was used 4 bicuspid upper and lower. They had orthodontic reason for extractions, in 35 days, at least. The sample had one hundred and twenty teeth that received orthodontic bands. The bands were fixed with polycarboxylate cement, and there was a space standardized between bands and one surface of teeth. The four bicuspid of each patients were randomized and nominated as A, B, C and D. These nominations determinated the sequence of the extractions and what was done in each tooth. All the patients had been submitted to the toothbrushing with or without fluoride for 35 days. After this period, the A tooth of each patient was extracted to serve as control. The others teeth (B, C and D) were extracted one by each week. The entire sample was analyzed through the clinical examination and by laser fluorescence (DIAGNOdent?) in three different times: before orthodontic bands, 28 days after fixed and then removed the bands and, the last one, 07 days after one of the three treatments (toothbrushing with or without fluoride, tooth paste with fluoride and mouth rinse with fluoride). At the beginning all groups (A, B, C and D) had the same conditions, no significant difference was found. The same situation was found in a clinical examination. The results of the DIAGNOdent? for the groups that used tooth paste without fluoride, with fluoride and mouth rinse with fluoride, after 28 days, there was no significant difference. Clinically, the white spot was formed in all teeth after 28 days. When it was compared the three treated groups, the group without fluoride in tooth paste had worst result than the others groups. But there was no significant association between the number of active and inactive white spots and the type of treatment that the teeth had received. The demineralization of the enamel surface, under the orthodontic bands, it happened in a few weeks. The exposition of the white spots in oral environmental resulted in an improvement, but it was not enough to return to the values from the base line, either for the toothbrushing and/or the use of fluorite mouth rinse. Mouth rinse and toothpaste with fluoride have showed to reduce the incidence of demineralization in the enamel, but none seems to be superior to another one in an in vivo study
O objetivo desse estudo cl?nico foi avaliar a efetividade da escova??o com e sem dentifr?cio fluoretado e o enxaguat?rio bucal fluoretado na forma de bochecho di?rio (NaF 0,05%) associado a escova??o com dentifr?cio fluoretado sobre as les?es brancas de esmalte produzidas in vivo. Este estudo se constituiu em um ensaio cl?nico controlado e randomizado. Para tanto, foram selecionados 32 pacientes do Curso de Especializa??o em Ortodontia da Associa??o Brasileira de Odontologia Sec??o do Estado do Rio Grande do Norte, que necessitavam como parte do tratamento de exodontias. Os cento e vinte e oito dentes receberam an?is ortod?nticos, cimentados com cimento de policarboxilato, com espa?o padronizado na superf?cie vestibular, S?tio Cariog?nico . Os quatro premolares de cada paciente foram aleatorizados individualmente, em dente A, B, C e D, com a finalidade de se determinar a seq??ncia das exodontias e os tipos de procedimentos a serem realizados para cada dente. Todos os pacientes foram submetidos ? escova??o com dentifr?cio sem fl?or por um per?odo de 35 dias. Ap?s esse per?odo, o dente A de cada paciente foi extra?do para servir como controle. Os demais dentes B, C e D foram extra?dos ap?s uma, duas e tr?s semanas, respectivamente. Os esp?cimes foram analisados atrav?s do exame cl?nico e da fluoresc?ncia a laser (DIAGNOdent?) antes da cimenta??o dos an?is ortod?nticos, 28 dias ap?s o desafio cariog?nico e 07 dias ap?s ter sido submetido a um dos tr?s tratamentos (escova??o com dentifr?cio sem fl?or, dentifr?cio com fl?or e bochecho com enxaguat?rio bucal fluoretado associado a escova??o com dentifr?cio com fl?or) institu?dos nesse estudo. Clinicamente, a les?o branca foi formada em todos os elementos dent?rios analisados ap?s 28 dias do desafio cariog?nico. Observou-se que n?o houve diferen?a estat?sticamente significativa entre as medianas para os valores do DIAGNOdent? e para os valores dos escores relacionados ao exame cl?nico entre os grupos de tratamentos ap?s 07 dias. Quando comparou-se os tr?s grupos tratados, o grupo dentifr?cio sem fl?or apresentou um n?mero de les?es brancas ativas maior que os grupos dentifr?cio com fl?or e bochecho com fl?or, nos quais ocorreu um predom?nio do n?mero de les?es brancas inativas. No entanto, n?o houve associa??o significativa entre o n?mero de les?es brancas ativas e inativas e o tipo de tratamento que os dentes receberam. A desmineraliza??o do esmalte subjacente aos an?is ortod?nticos mal adaptados ? um processo r?pido e ocorre dentro de poucas semanas. A exposi??o das les?es brancas de esmalte, ativas ao meio bucal, resulta em uma r?pida inativa??o das mesmas, mas n?o o suficiente para retornar aos valores da linha base, seja por dist?rbios mec?nicos da escova??o e/ou a utiliza??o de enxaguat?rio bucal fluoretado associado ao dentifr?cio fluoretado. Os dentifr?cios a base de fl?or e os enxaguat?rios bucais fluoretados t?m mostrado reduzir a incid?ncia de desmineraliza??o do esmalte, mas nenhum parece ser superior ao outro tomando como base o modelo de c?rie in vivo

Повний текст джерелаWhite Spot Lesions (WSLs) are a common iatrogenic finding along brackets used in orthodontic treatment. WSLs are frequently noticed as small opaque lesions with lessened radiolucency which might have a lasting unaesthetic effect. These lesions might range from small lines along bracket peripheries and less frequently might be observed as larger demineralized areas with or without cavitation. The development of WSLs is principally enhanced by the accumulated plaque around brackets due to a compromised oral hygiene that might be aggravated by the presence of dental crowding. Furthermore, The presence of fixed orthodontic apparatus leads to alteration in the oral microflora causing reduction in the PH level and increased bacterial adherence to the metal facade through electrostatic effect. There are several preferences for treatment of WSL, ranging from conservative approaches relying on remineralization to invasive techniques. The severity of lesions is a determinant of which option is most appropriate. The management of WSLs is based on remineralization strategies or in other situations on a minimal-invasive camouflage of the lesions. Although orthodontic WSLs are one of the most frequent and most visible adverse effects of comprehensive fixed appliance treatment, the efficacy of their intervention continues to be assessed in the literature and up to date there is no consensus on the best evidence-based approach to manage such lesions. Therefore, the aim of the present thesis is to review and critically appraise the contemporary evidence related to causes, diagnosis, prevention, risk evaluation and management of WSL associated with orthodontic appliances. Furthermore, clinical recommendations that might be useful for both the general dentist as well as the orthodontist. This literature review will be undertaken by searching the database engines, Pubmed, Medline, Google Scholar, B-on and Science Direct. The search will include the literature published inbetween 2005-2021.

Повний текст джерелаMolar-incisor hypomineralization (MIH) is a structural defect of the enamel. Affected teeth present isolated opacities, asymmetric in homologous teeth, white, yellow or brown stains, depending on the severity of the lesion, affecting, as the name suggests, the first molars and incisors of the permanent dentition. The esthetic demands of patients are increasingly important, as the colored stains on the enamel can, depending on their location and severity, have a great aesthetic impact on our patients' smiles and greatly impair their social life. Currently, there are simple and minimally invasive solutions to deal with these situations. One of the most widely used treatment options is the infiltrative resin technique ICON®, its action based on erosion of the surface of the lesion through the use of an acid and the subsequent infiltration of a low viscosity resin. The main objective of this narrative literature review is to recall the etiological factors, diagnosis, clinical characteristics and treatment of molar-incisive hypomineralization lesions, as well as to demonstrate the effectiveness of the ICON® technique in removing these lesions.

Повний текст джерелаObjective: Review the available scientific literature on the most current preventivetherapeutic approach to White Spot Lesions (WSL) in pediatric patients using fluoridated and non-fluoridated remineralizing agents. Methods: Bibliographic search of scientific articles published in the databases: PubMed, B-On and Web Of Science, between 1999 and 2019. Search terms were articulated using the Boolean AND and NOT markers and defined inclusion and exclusion criteria for the selection of manuscripts. In total, 17 articles were analyzed. Subject: WSL represents a type of injury that is quite prevalent in children. The success in the preventive-therapeutic approach of these lesions depends on the early diagnosis and the application of remineralizing agents, whose objective should be to prevent and intercept these lesions to the detriment of more invasive treatments. The current remineralizing agents provide not only an effective intervention with increasing the potential for remineralization of the lesions, but also contribute to an improvement of the associated aesthetics.

Повний текст джерелаIntroduction: White spot lesion represents the first visual alteration in the enamel caused by caries. The progression of these lesions can be arrest with non-invasive treatments before cavitation. The thesis aims to analyze changes in the enamel after applying the infiltrant resin in white spot lesions, namely penetration depth, surface roughness, microhardness, and shear bond strength. Materials and Methods: The search was conducted in Medline, Pubmed, Cochrane Central Register of Controlled Trials, Embase, Web of Science, Scholar, and LILACS until May 2021. In-vitro studies that assess depth penetration, roughness, microhardness, and shear strength before and after resin infiltration were included. Methodological quality was evaluated using the Joanna Briggs Institute Clinical Appraisal Checklist for Experimental Studies. Pairwise ratio of means meta-analyses allowed evaluating of the enamel properties, before and after resin infiltration, on enamel surfaces with and without white spot lesions. Results: From a total of 1604 articles, 48 were included for meta-analytic quantitative evaluation. In the parameter of enamel surface roughness there was an improvement by 35% in sound enamel (95% CI: 0.49-0.85, p<0.0021) and 54% (95% CI: 0.29; 0.74, 0.0012) in white spot lesions. Enamel microhardness was reduced by 24% (95% CI: 0.73; 0.80, p<0.001) and increased by 68% (95% CI: 1.51; 1.86, p<0.001) in white spot lesions. Shear strength in enamel was reduced by 25% in sound enamel (95% CI: 0.60; 0.95, p<0.001) and increased by 89% (95% CI: 1.28; 2.79, p<0.001) in white spot lesions. At penetration depth, the application of infiltrating resin led to occlusion of 65.39% (95% CI: 56.11; 74.66, p=0.01, I2=100%) of the white spot lesion. Conclusions: The application of infiltrating resin promotes recovery of enamel properties, both in healthy enamel and in white spot lesions. In the future, studies with defined protocols and appropriate controls are needed with long-term follow-ups.
Introdução: As lesões de white spot são as primeiras alterações do esmalte devido à cárie dentária e tratamentos não-invasivos têm sido sugeridos para travar a progressão da lesão. O objetivo desta tese é analisar as alterações da superfície do esmalte com e sem lesão de white spot após aplicação da resina infiltrativa, nomeadamente profundidade de penetração, rugosidade, microdureza e resistência ao cisalhamento. Materiais e Métodos: A pesquisa foi realizada no Medline, Pubmed, Cochrane Central Register of Controlled Trials, Embase, Web of Science, Scholar, and LILACS até maio de2021. Estudos in-vitro que avaliam a profundidade de penetração, rugosidade, microdureza e resistência ao cisalhamento antes e depois da infiltração de resina foram incluídos. A qualidade metodológica foi avaliada através do Joanna Briggs Institute Clinical Appraisal Checklist for Experimental Studies. Meta-análises pairwise de rácio de médias avaliaram as alterações das propriedades do esmalte com e sem lesão white spot. Resultados: De um total de 1604 artigos, 48 foram incluídos para avaliação quantitativa meta-analítica. A rugosidade de superfície do esmalte melhorou 35% (95% CI: 0.49-0.85, p<0.0021) no esmalte saudável e 54% (95% CI: 0.29-0.74, 0.0012) nas lesões de white spot. A microdureza reduziu 24% (95% CI: 0.73-0.80, p<0.001) no esmalte saudável e aumentou 68% (95% CI: 1.51-1.86, p<0.001) nas lesões de white spot. A força de cisalhamento reduziu 25% (95% CI: 0.60-0.95, p<0.001) no esmalte saudável e aumentou 89% (95% CI: 1.28-2.79, p<0.001) em lesões de white spot. A profundidade de penetração da resina infiltrativa levou à oclusão de 65,39% (95% CI: 56.11-74.66, p=0.01, I2=100%) da lesão de white spot. Conclusões: A aplicação da resina infiltrativa promove a recuperação das propriedades do esmalte, tanto em esmalte são como em lesões de white spot. Futuramente, estudos com controlos apropriados são necessários bem como follow-ups a longo prazo.

Повний текст джерелаThe concepts of dental demineralization / remineralization, dental caries and white spot lesions or White Spots are discussed in the current literature with particular interest, given their determinant role in the functional and aesthetic prognosis of the dental parts involved. The purpose of this literature review is: to discuss demineralization / remineralization concepts from a histological and clinical perspective, with a primary focus on the clinical involvement of white spot lesions or White Spots. A narrative review on the subject under analysis is proposed, considering mainly the last 10 years of publication (2010 to 2020). The indexing terms used were “Demineralization”; "Epidemiology"; "Etiology"; "Histology"; "Remineralization"; "White Spot Lesions". and equivalent terms in English. They were used alone or in combination. Enamel is the most visible dental tissue in the oral cavity and remains an enormous challenge in terms of its repair, given the uniqueness of its formation and histological organization. Remineralization strategies and the prevention of demineralization are crucial in dentistry.

Повний текст джерелаGiven the current concepts of dental caries disease and the need for early diagnosis of enamel demineralization lesions this study intended to carry out a descriptive literature review with the following objectives: to describe the main concepts about the injuries of enamel non-cavitated carious lesions related to prevalence, severity, forms of detection and registration; it was intended also to perform a review on chemical action of remineralizing and infiltrating agents in non-cavitated enamel lesions, focusing primarily on the identification, description, presentation modes, mechanism of action, clinical performance mode and, the main evidence in vitro and in vivo regarding the action of remineralizing and infiltrating agents. For this purpose were analyzed and interpreted the studies conducted up to the present day and for that was used PICO method, evaluation and synthesis of empirical evidence to include in this study. Final findings resulted from the analysis of 148 articles (qualitative and quantitative profile) of which 104 publications were literature review and 44 were empirical, where 13 and 31 were related to infiltrants and remineralizing agents, respectively. keywords used: "enamel remineralization," "ICDAS", "white spot lesion", "non-cavitated caries lesions", "resin infiltration," "infiltrants," "dental caries detection", "remineralizing agents" "demineralization-remineralization" and "dental toothpaste." Inclusion criteria were observational studies, in vivo and in vitro, narrative reviews, systematic and meta-analysis, written in English; no time period was set on the literature research, giving however more relevance to publications between the years 2005 and 2016. As exclusion criteria was considered all publications not available in full text, and those that referred to dentin carious lesion or enamel cavitated carious lesions, odontopediatric injuries, root caries and restorative materials that were not infiltrating agents.It was possible to conclude that both techniques (actuation by remineralizing and resin infiltration agents) prove to be effective in the remineralization of enamel incipient caries. The remineralising agents present a wide range of formulations according to the needs of each patient, while infiltrating agentes showed to be a recent technical approach with only one commercially agent available for its application in the dental office.
