Dental Press Journal of Orthodontics 17, no 6 (décembre 2012) : 89–96. http://dx.doi.org/10.1590/s2176-94512012000600019.
Texte intégralRésumé :
OBJECTIVE: The objective of this study was to verify from a school-based epidemiological survey, the prevalence of anterior open bite, analyzing the influence of pacifier habit in the school. METHODS: The first step was a questionnaire for the parents, and later clinical examinations in 237 school children, 3-14 years old, in the city of Santo Expedito do Sul/RS, Brazil. RESULTS: The population gender distribution was 50.3% boys and 49.4% girls with a mean age of 8.63 years, and 16% had primary dentition, 50.2% mixed dentition and 33.8 % permanent dentition. There was a 22.8% prevalence of anterior open bite, obtaining a significant association between anterior open bite and the pacifier sucking habit on the three dentitions. CONCLUSION: The duration and frequency of the habit were strongly associated with anterior open bite malocclusion in the deciduous and mixed dentitions.

Texte intégralRésumé :
Aim and objective: The objective of this in-vivo study was to evaluate toothwise and archwise sulcus depth in human primary, mixed and permanent dentition of Indian population.Method: The study included 40 subjects (22 males and 18 females) of an age range 4-25 years. Subjects were divided into 3 groups – the primary dentition (4-6 years) mixed dentition (7-13 years) and adult dentition (16-25 years). All the parameters were measured in upper and lower anterior segments.Results: Gingival sulcus depth (GSD) was measured archwise and toothwise in different dentitions and overall dentition wise without differentiating archwise and toothwise. GSD was significantly higher in maxillary mixed dentition (1.75±0.75) followed by permanent and primary dentition. In all the dentition, maxillary central incisor showed significant GSD.Conclusion: The sulcus depth is maximum in mixed dentition followed by primary and permanent dentitions and significantly higher in maxillary central incisor.

Texte intégralRésumé :
Aim: to analyze the prevalence of different definitions of functional dentition, prosthodontic status and associated factors, in an indigenous population from Brazil. Methods: a cross-sectional oral health survey was conducted with Indigenous adults aged 35-44 years. A single examiner collected clinical data through oral examinations and sociodemographic data using a structured questionnaire. Dentitions were classified according to four classification systems of functional dentition: FDWHO (> 20 teeth), FDGROUP2 (> 10 teeth in each arch), FDGROUP3 (all anterior teeth), and FDGROUP4 (> 10 teeth in each arch, all anterior teeth, and sufficient posterior region). Use and need of prosthodontics was also evaluated. Uni and multivariate analysis were conducted at the level of significance of 5%. Results: Indigenous adults presented considerably low frequencies of prosthodontic use and functional dentition, independently of the definition analyzed. Substantial differences of prevalence rates were observed among the four definitions of functional dentition, ranging from 48.62% to 11.93%. Age and municipality were associated with use of dental prosthesis and prosthodontic need, respectively. Significant discrepancies in functional dentition rates were observed regarding sex and time of the last dental appointment. Conclusions: Indigenous adults are severely affected by tooth loss and, consequently, by low frequencies of functional dentition. The scenario is worsened by the elevated need of the population for prosthodontics. The phenomenon was associated with age, sex, access to specialized dental care and time of the last dental visit.

Texte intégralRésumé :
Reduction of the anterior dentition (i.e. incisors and canines) is a major adaptative trait of the Rhinocerotidae among Perissodactyla. However, the corresponding evolutionary sequence was lacking a robust phylogenetic frame to support it thus far. Here, we describe a new Oligocene species of Rhinocerotinae, Mesaceratherium sp. nov. from the Swiss locality of Bumbach (MP25 reference level). In addition, we identify the only known complete mandible of Epiaceratherium magnum , an early-branching rhinocerotid, as well as one of the earliest European rhinoceroses. We also compute a parsimony analysis based on morpho-anatomical characters to assess their phylogenetic position and elucidate the early evolution of the Rhinocerotidae. Our results allow to propose a new scenario for the reduction of the anterior dentition in which upper and lower dentitions would have undergone distinct evolutionary trajectories.

Texte intégralRésumé :
Aim: To evaluate the association between the frequency of malocclusions in the anterior sextant with dentition type, age, and sex. Material and methods: A descriptive, transversal and prospective study was carried out, in a convenience sample of 200 patients between 3 and 14 years old, of both sexes who attended the pediatric dentistry clinic of Dentistry Faculty from Autonomous University of Tlaxcala, Mexico. A dentist was standardized by a direct method (k=0.998, p=0.0001). Results: Crossbite and edge to edge bite were the most frequent (18% and 17% respectively), in no case the alterations in the previous sextant were related to sex, except altered overjet with age and dentition type (likelihood ratio=18,169, p=0.0001) (X2=18.820, p=0.0001). Conclusion: These observations highlight the importance of the diagnosis of possible alterations in the occlusion of the anterior sextant in both dentitions, in order to preventatively avoid major sequelae.

Applied Sciences 10, no 15 (31 juillet 2020) : 5301. http://dx.doi.org/10.3390/app10155301.
Texte intégralRésumé :
The position of the upper first molar (UFM) is currently considered the “key of occlusion”. The purpose of this study was to evaluate the prevalence of the mesiorotated UFM, and its relationship with anterior dental crowding in mixed and permanent dentition. Intra-oral scans of upper dental arches of 180 subjects with mixed dentition and 169 subjects with permanent dentition were retrospectively analyzed to investigate the presence of UFM mesiopalatal rotation and presence of anterior crowding. The occlusal relationship and the presence of caries were also recorded. In subjects with permanent dentition, there was a statistically significant correlation between anterior crowding and UFM mesiopalatal rotation (Pearson’s chi-square = 9.03; p = 0.06). Among cases with permanent dentition, subjects with UFM mesiopalatal rotation showed an OR = 3.28 (95% CI = 0.99–10.93; p = 0.042) of moderate/severe anterior dental crowding, respect to subjects without UFM rotation. In subjects with mixed dentition, there was a statistically significant correlation between molar occlusal relationship and UFM mesiopalatal rotation (Pearson’s chi-square = 14.98; p = 0.002), and subjects with molar class II showed a OR = 10.2 (95% CI = 2.16–48.22; p = 0.0005) to present UFM mesiopalatal rotation, with respect to subjects with molar class I. UFM mesiopalatal rotation is associated to anterior dental crowding in permanent dentition, and to class II malocclusion in mixed dentition.

Phone: +91 9886651419 Email: divyacreddy@yahoo.com ABSTRACT: Anterior crossbite results from lingual positioning of maxillary anteriors in relation to mandibular anterior teeth. It can be due to either skeletal or dental problems, involving one or more teeth. These crossbites can be considered as a functional problem in a young child, which may result in skeletal problems as the child transitions into permanent dentition. Often there is dilemma among the clinicians regarding the correction of these crossbites in primary and early mixed dentition periods especially owing to the child’s age and cooperative ability. This paper aims to discuss various views on early treatment of anterior crossbites in children, the treatment objectives and different treatment strategies discussed in the literature

Texte intégralRésumé :
Successful orthodontic resolution of bimaxillary dentoalveolar protrusion depends on successful retraction of anterior dentition, which also involves acquiring proper buccolingual inclination and vertical position of anterior teeth. To fulfill these requirements, clinicians have devised numerous biomechanical and surgical orthodontic options. A palatal retractor for retraction of maxillary anterior dentition is the result of clinician’s long-time creative endeavors and an evolution of the biomechanical design. A palatal retractor splints the maxillary anterior dentition on the lingual side with bonded mesh plates connected by a supporting wire. Two long palatally extended arms are soldered to the supporting wire where adequate retraction force can be applied. Palatal retractors have several advantages over conventional bracket/wire systems. The two most prominent ones are biomechanical superiority and esthetic invisibility. As the palatal retractor is positioned on the lingual surface of the maxillary anterior dentition, it is not visible from the frontal view and since the anterior dentition retraction constitutes a significant portion of the total treatment time in extraction orthodontic treatment, it is a distinct esthetic advantage. Biomechanical disadvantage of the conventional bracket/wire system lies in its innate ineffectiveness of the torque and vertical control because of the long distance between the point of force application and the center of resistance of the anterior dentition. A combination of TADs and palatal retractors provides the possibility of maximizing control of both the torque and vertical position. This article aims to describe clinical considerations, applications, and results of palatal retractor use in clinical cases. Keywords: extraction treatment, anterior teeth retraction, palatal retractors, temporary anchorage devices.

Texte intégralRésumé :
Introduction: Amelogenesis imperfecta (AI) is a rare genetic disease affecting both dentitions. Factors such as age, socioeconomic status, dentition and AI type and severity should be taken into consideration in treatment planning. Aim: This retrospective study aimed to assess the survival rate of AI main restorative options and the effects of gender and dentition type. Methods: The study sample comprised 28 dental records of patients aged 5-17 years affected by AI (15 females, 13 males) and with anterior and/or posterior restoration in primary and/or permanent tooth/teeth. The fate of each restoration was classified into three categories: failed, withdrawn and censored and analyzed by the life table method of survival analysis. Results: Out of 233 restorations performed, the most frequently used restoration was preformed metal crowns (PMCs), followed by anterior composite, posterior composite, adhesive casting, Ketac fill and amalgam respectively. The two main restorations, PMCs and anterior composite were included in the statistical analysis. The survival rate of PMCs was significantly higher than anterior composite (p<0.001). The anterior composite restorations survived significantly longer in males (p<0.05). Females had significantly better survival rate of PMCs (p<0.05). There was no statistically significant effect of the operator group of restoration survival. Conclusion: The anterior composite restorations survived significantly longer in males and females had significantly better survival rate of PMCs than males.

Nicholas, Christina Lynne. « The ontogeny of nasal floor shape variation in Homo and the influence of facial size, the anterior dentition, and patterns of midfacial integration ». Diss., University of Iowa, 2015. https://ir.uiowa.edu/etd/1710.
Texte intégralRésumé :
Variation in the shape and position of the internal nasal floor relative to the lower border of the piriform aperture in the genus Homo has been described as having three primary shape configurations: level, sloped, or depressed. The high frequency of depressed nasal floors among Neandertals relative to other fossil and extant groups (>80%) had originally led to the idea that nasal floor depression was related to an overall enlarged nasal capsule - an adaptive feature that would have been under selection among Neandertals living in cold, glacial climates. For a variety of reasons, subsequent research has found little empirical or theoretical support for this adaptive idea. Recent research on extant humans has also demonstrated that nasal floor shape variation, unlike many other midfacial traits, does not arise until well after birth, with nasal floor depression (when it occurs) appearing at the earliest around 3.0 years of age. Furthermore, nasal floor depression was also shown to correspond with a vertically expanded premaxillary region. Thus, it was hypothesized that nasal floor depression might be related to variation in key developmental and morphological aspects of the anterior maxillary dentition. This study metrically quantifies nasal floor topography for the first time in order to more objectively examine patterns of shape variation and to test explicit hypotheses regarding potential causative factors for nasal floor variation. The variables examined include anterior tooth dimensions, dental developmental rate, aspects of midfacial shape, overall facial size, and patterns of premaxillary/post-maxillary integration. It was found that among these, only dental developmental rate was clearly correlated with internal nasal floor shape. This result indicates that aspects of anterior dental development may indeed be a causative factor in the development of nasal floor shape variation. The existing visual discrete coding system for nasal floor topography was also evaluated in light of the new, quantitative data produced by this study as well as a critical comparison of the consistency of nasal floor topography definitions used previously in the literature. While it is suggested that quantitative data are preferable to qualitative data for this trait when possible, limitations in research methods for collecting quantitative data on osteological and fossil collections remain difficult to overcome. Thus a new, two-category presence/absence based system for describing nasal floor shape is proposed.

Este estudo avaliou o posicionamento de caninos superiores permanentes em relação à largura do arco dentário superior e ao espaço na região anterior em pacientes na fase da dentadura mista. Foram analisados radiografias panorâmicas e modelos de estudo pré-tratamento de pacientes sem caninos deslocados (n = 68; 34 do gênero masculino; 34 do gênero feminino). A amostra foi dividida em idade e gênero. A largura do arco dentário e o espaço na região anterior entre os incisivos permanentes foram medidos. A posição e a inclinação do canino na radiografia panorâmica foram avaliadas em relação à linha mediana. Os resultados deste estudo mostram que não houve diferenças no posicionamento dos caninos permanentes em relação às variáveis analisadas. A média da angulação do canino superior em relação à linha mediana foi 6,2o e 10o para o gênero feminino e 9,2o e 11o para o masculino, respectivamente para o lado direito e esquerdo.This study investigated the correlation between maxillary dental arch width, anterior space and the position of canines in patients during the mixed-dentition stage. Pretreatment Panoramic radiographs and dental casts were evaluated of randomly selected patients in the mixed dentition without maxillary canines displaced (n = 68; male, 34; female, 34). This sample was matched according to sex and age. Arch widths between the maxillary canines deciduous and anterior space between permanent incisors were measured and recorded. The position and inclination of canine on panoramic radiography was investigated. The results of this study showed that there are similarities in the position of the permanent canines in all cases and in both gender. The average of the canine\'s angulation to the mid-sagital plane was 6,2o and 10o for female and 9,2o and 11o for male, respectively to the right and left side.

Aws, Ghassan. « Analysis of symmetry in the anterior human dentition and its application in the evaluation and correction of postural distortion in the photographic recording of human bite marks ». Thesis, University of Edinburgh, 2006. http://hdl.handle.net/1842/1348.
Texte intégralRésumé :
Postural distortion of human bite marks on skin occurs when photographing a bite mark in a body position other than the position of the body at the time of biting. Postural distortion in the bite mark may introduce significant changes in both the shape and size of the recorded marks. As a result, the analysis of the marks may be hindered and a proper comparison between the bite mark and the causal dentition may be precluded. Therefore, a method by which postural distortion in a bite mark photographic record can be evaluated and eliminated with minimal operator subjectivity is required. This study describes the development of an objective technique for evaluating postural distortion in bite mark photographic records and for minimising postural distortion during photography of bite marks. The source for developing these techniques was provided by digitally analysing the symmetry of dental arches in a defined population including males and females (236 subjects) whose ages ranged between 20 and 30 years. The analysis resulted in quantifying a mathematical relationship between the biting edges of each homologous pair of the anterior teeth and specified reference lines. The validity of the analytical method of dental arch symmetry is discussed. The developed techniques were applied to posturally distorted (test) bite marks. The results demonstrate the validity of the developed techniques in determining postural distortion and recording correct images (shown to resemble the biters dentition) of the test bites. Suggestions for further work are proposed.

Texte intégralRésumé :
O objetivo deste estudo foi avaliar características oclusais e miofuncionais orais em crianças entre 3 e 5 anos de idade, com mordida aberta anterior e também verificar o comportamento dessas características após remoção do hábito de sucção de chupeta. Participaram 69 crianças, 34 com oclusão normal (Grupo Controle) e 35 com mordida aberta anterior (Grupo Mordida Aberta). No Grupo Mordida Aberta, a média da mordida aberta anterior foi 2,96 mm, da sobressaliência foi 4,1 mm e da distância intercanina superior foi 28,7 mm. No Grupo Controle, a média da sobressaliência foi 2,6 mm e a da distância intercanina superior foi 30,3 mm. A média da sobressaliência foi maior (p=0,001) e a média da distância intercanina superior foi menor (p<0,001) no Grupo Mordida Aberta que no Controle. O número de crianças com relação canina classe II foi maior no Grupo Mordida Aberta que no Controle (p<0,001). A análise de regressão logística univariada mostrou que maior sobressaliência, menor distância intercanina superior e relação canina classe II coexistiram com a mordida aberta anterior. No Grupo Mordida Aberta, o número de crianças com postura de lábios entreabertos em repouso (60,0%), alteração no tônus labial (68,6%), postura inadequada de língua em repouso (65,7%), alteração no tônus de bochechas (42,9%), interposição lingual anterior durante a deglutição (91,4%) e interposição lingual anterior durante a fala (85,7%) foi maior (p<0,05) que no Grupo Controle (respectivamente 35,3%, 35,3%, 23,6%, 17,7%, 32,4% e 38,2%). A análise de regressão logística múltipla identificou a interposição lingual anterior durante a deglutição (odds ratio 18,97) e durante a fala (odds ratio 9,24) bem como a postura de lábios entreabertos em repouso (odds ratio 6,23) como as principais características miofuncionais orais nas crianças com mordida aberta anterior. Das 35 crianças do Grupo Mordida Aberta, 27 apresentavam hábito de sucção de chupeta ao início do estudo e, após orientação, 15 abandonaram o hábito e 12 diminuíram a freqüência do hábito. Observou-se que a taxa de sucesso na remoção do hábito foi 55,6%, sem diferença entre gêneros e idades. A remoção do hábito favoreceu, após 3 meses de acompanhamento, redução média da mordida aberta anterior de 1,97 mm, sendo maior (p<0,001) que nas crianças que diminuíram o hábito (0,33 mm). A média da redução da sobressaliência nas crianças que abandonaram o hábito foi 0,6 mm e a média do aumento da distância intercanina superior foi 0,67 mm, mas não foram estatisticamente diferentes das crianças que diminuíram o hábito (respectivamente 0,0 mm e 0,50 mm) nem do Controle (respectivamente 0,2 mm e 0,42 mm). A remoção do hábito de sucção de chupeta promoveu melhora na postura de lábios em repouso (p=0,0313), favoreceu a respiração nasal (p=0,0078) e reduziu a ocorrência de interposição lingual anterior durante a deglutição (p=0,0078), após 3 meses de acompanhamento. A análise de regressão logística univariada identificou a postura de língua inadequada em repouso, como a principal característica miofuncional oral capaz de impedir a correção espontânea da mordida aberta anterior nas crianças avaliadas durante esse período (odds ratio 17,50)The aim of this study was to evaluate occlusal and oral myofunctional characteristics in children between 3 and 5 years old, with anterior open bite and also to verify the behavior of these characteristics, 3 months after removal of pacifier sucking habit. Sixty nine children participated, 34 presented normal occlusion (Control Group) and 35 presented anterior open bite (Open Bite Group). In the Open Bite Group, the mean anterior open bite was 2.96 mm, the mean overject was 4.1 mm and the mean upper intercanine distance was 28.7 mm. In the Control Group, the mean overject was 2.6 mm and the upper intercanine distance was 30.3 mm. The mean overject was larger (p=0.001) and the mean upper intercanine distance was smaller (p<0.001) in the Open Bite Group than in the Control Group. The number of children with canine class II relationship was larger in the Open Bite than in the Control Group (p<0.001). Simple logistic regression analysis showed that larger overject, smaller upper intercanine distance and class II canine relationship coexisted with anterior open bite. In the Open Bite Group, the number of children with incompetent lips at rest (60.0%), inadequate labial tonus (68.6%), inadequate posture of tongue at rest (65.7%), inadequate cheeks tonus (42.9%), tongue thrust during swallow (91.4%) and tongue thrust during speech (85.7%) was larger (p<0.05) that in the Control Group (respectively 35.3%, 35.3%, 23.6%, 17.7%, 32.4% and 38.2%). Multiple logistic regression analysis identified tongue thrust during swallow (odds ratio 18.97) and during speech (odds ratio 9.24) as well as incompetent lips at rest (odds ratio 6.23) as the main oral myofunctional characteristics in children with anterior open bite. Of the 35 children in the Open Bite Group, 27 presented pacifier sucking habit at the beginning of the study and after instruction, 15 abandoned the habit and 12 reduced the frequency of the habit. It was observed that the success rate for habit removal was 55.6%, without difference related to sex and age. The habit removal favored, after 3 months of attendance, 1.97 mm mean reduction of anterior open bite, being larger (p<0.001) compared with those children that reduced the habit (0.33 mm). The mean reduction of the overject in children that abandoned the habit was 0.6 mm and the mean increase of the upper intercanine distance was 0.67 mm, but were not statistically different from the children that reduced the habit (respectively 0.0 mm and 0.50 mm) nor from the Control (respectively 0.2 mm and 0.42 mm). The removal of the pacifier sucking habit promoted improvement in the posture of lips at rest (p=0.0313), favored the nasal respiration (p=0.0078) and reduced the occurrence of tongue thrust during swallow (p=0.0078) after 3 months of attendance. Simple logistic regression analysis identified the inadequate posture of the tongue at rest, as the main oral myofunctional characteristic capable to prevent the spontaneous correction of the anterior bite in the appraised children during that period (odds ratio 17.50)

Texte intégralRésumé :
L’os cortical et la dentine sont deux tissus biologiques ayant des similarités dans leur architecture génétique, leur structure, leur composition et leur développement embryonnaire, qui ne sont pas partagées avec l'émail. Plusieurs observations permettent de suggérer l’existence d’un développement post-natal coordonné des deux tissus chez les hominines. Par exemple, les Néandertaliens présentent des volumes d'os cortical plus élevés dans leur squelette infra-crânien et une dentine plus robuste par rapport aux humains modernes, tandis que les volumes absolus d’émail sont similaires entre les deux taxons. L’étude des spécimens immatures néandertaliens montre que cette robustesse de l’os et de la dentine est déjà présente aux premiers stades du développement. Dans cette thèse, nous avons cherché à comprendre si les affinités structurelles et développementales entre l’os cortical et la dentine pouvaient induire un développement post-natal coordonné de ces deux tissus chez les humains modernes. Pour ce faire, nous avons mesuré la variation conjointe des volumes d’os cortical et de dentine dans un échantillon d’humains modernes, composé de 12 individus immatures et de 70 adultes. A partir d’acquisitions microtomographiques des os du bras, de l’avant-bras et de la denture antérieure maxillaire, nous avons mené une approche méthodologique combinant la quantification des volumes d'os cortical et de dentine avec l'analyse de leur distribution topographique. Nous mettons en évidence une désynchronisation entre le développement de l’os cortical et de la dentine pendant la croissance des individus immatures, se traduisant par une absence de covariation des volumes de tissus chez ces derniers. Une forte covariation os-dentine est observée chez les adultes, suggérant que le développement post-natal de ces deux tissus pourrait être influencé par des facteurs communs, une fois la maturation osseuse et dentaire achevée. Cette thèse montre notamment que le milieu hormonal joue un rôle prédominant dans le développement post-natal de ces tissus, tandis que l’histoire biomécanique du squelette semble avoir un impact plus limité sur leur développement. Une analyse préliminaire de la covariation os-dentine a été menée sur des individus chimériques de Paranthropus, d’Australopithecus et néandertaliens. La plupart des individus montrent une déviation par rapport à la relation os-dentine des humains modernes, caractérisée par des volumes de dentine plus élevés dans les taxons fossiles et des volumes d'os cortical similaires à ceux des humains modernes. Un ralentissement de la croissance et du développement a été décrit chez Homo sapiens par rapport aux hominines fossiles, pouvant expliquer la singularité de ce taxon dans cette relation os-dentine. Ce travail doctoral apporte une contribution originale à l’étude des volumes et de la distribution des tissus osseux et dentaires dans divers taxons hominines et offre une réflexion sur l’impact des facteurs génétiques, environnementaux et évolutifs agissant sur leur développementCortical bone and dentine are two biological tissues sharing a common genetic origin, overall structure, composition, and embryological development, distinct from those of enamel. Various observations suggest the possibility of coordinated postnatal development of these two tissues in hominins. For example, Neandertals display higher cortical bone volumes in their infra-cranial skeleton and greater dentine robustness compared to modern humans, while absolute enamel volumes are similar between the two taxa. Studies of immature Neandertal specimens indicate that their cortical bone and dentine robustness may be present from early developmental stages. In this doctoral research, we aimed to understand whether the structural and developmental affinities between cortical bone and dentine could lead to coordinated postnatal development of these tissues in modern humans. To this end, we measured the coordinated variation of cortical bone and dentine volumes in a sample of modern humans, comprising 12 immature individuals and 70 adults. Using microtomographic acquisitions of the arm, forearm bones, and anterior dentition, we conducted a methodological approach combining the quantification of cortical bone and dentine volumes with the analysis of their topographic distribution. Our results highlight a developmental desynchronization between cortical bone and dentine during the growth of immature individuals, leading to weak covariation between their cortical bone and dentine volumes. The bone-dentine covariation signal is stronger in adults, suggesting that common factors may influence postnatal development of these tissues once skeletal and dental maturation is achieved. This research highlights the predominant role of the hormonal milieu in the postnatal development of these tissues, while the biomechanical history of the skeleton appears to have a more limited impact. A preliminary analysis of bone-dentine covariation was conducted on chimeric individuals of Paranthropus, Australopithecus, and Neandertals. Most of these individuals deviate from the modern human bone-dentine relationship, characterized by higher dentine volumes in fossil taxa and cortical bone volumes similar to those of modern humans. A slowdown in growth and development has been described in Homo sapiens compared to fossil hominins, which may explain the unique bone-dentine relationship seen in this taxon. This doctoral thesis provides an original contribution to the study of bone and dental tissue volumes and distribution in various fossil and extant hominin taxa, offering insights into the impact of genetic, environmental, and evolutionary factors acting on their development

Texte intégralRésumé :
Facial pain occupies the area below the orbitomeatal line, above the neck and anterior to the pinnae. It comes in many forms and may or may not be accompanied by other symptoms. It may be acute, subacute, or chronic, arise from local pathology (e.g. dentition, parotid gland, sinus), be referred from other structures (e.g. pain behind the eye may be due to cervical spondylosis or sphenoidal sinusitis) or be part of a neurological syndrome such as trigeminal neuralgia or persistent idiopathic facial pain (previously termed atypical facial pain). There is a wide differential diagnosis. As with headache, serious causes are rare. Some benign conditions are particularly painful (trigeminal neuralgia, cluster headache) but have effective treatment.

Texte intégralRésumé :
Dental trauma in childhood and adolescence is common. At 5 years of age 31–40% of boys and 16–30% of girls, and at 12 years of age 12–33% of boys and 4–19% of girls, will have suffered some dental trauma. Boys are affected almost twice as often as girls in both the primary and the permanent dentitions. The majority of dental injuries in the primary and permanent dentitions involve the anterior teeth, especially the maxillary central incisors. Concussion, subluxation, and luxation are the most common injuries in the primary dentition, while uncomplicated crown fractures are most common in the permanent dentition. Prognosis of traumatic injuries has improved significantly in the last 20 years. This has been largely due to a greater understanding of dental pulp reaction patterns and vital pulp therapies. Children are most accident prone between 2 and 4 years for the primary dentition and between 7 and 10 years for the permanent dentition. Coordination and judgement are incompletely developed in children during the primary dentition years, and the majority of injuries are due to falls in and around the home as the child becomes more adventurous and explores his/her surroundings. Most injuries in the permanent dentition are caused by falls and collisions while playing and running, although bicycles are a common accessory. The place of injury varies in different countries according to local customs, but accidents in the school playground remain common. Sports injuries usually occur in the teenage years and are commonly associated with contact sports. Injuries due to road traffic accidents and assaults are most commonly associated with the late teenage years and adulthood, and are often closely related to alcohol abuse. One form of injury in childhood that must never be forgotten is child physical abuse or non-accidental injury (NAI). More than 50% of these children will have orofacial injuries (see also Chapter 4, Safeguarding Children). Accidental dental injuries can result from direct or indirect trauma. Direct trauma occurs when a tooth receives a direct blow, making this sort of injury more common at the front of the mouth.

Texte intégralRésumé :
In the literature, Dentinal Hypersensitivity (DH) is considered to arise from exposed dentin and patent dentinal tubules. However, clinical observation of recurrent DH sensitivity indicates it can occur in the presence or absence of exposed dentin. Quantified occlusal contact force and timing parameters have been ignored in studies assessing hypersensitive teeth. This chapter introduces a novel occlusal concept: Frictional Dental Hypersensitivity (FDH). Clinical evidence from combining computerized occlusal analysis and electromyography is presented linking opposing posterior tooth friction and muscular hyperactivity to Dentin Hypersensitivity. This chapter proffers how occlusion, muscular TMD symptoms, and frictional Dentin Hypersensitivity are all related. Lastly, a Pilot Study is presented that used a Visual Numerical Analog scale to quantify Dentin Hypersensitivity resolution observed in symptomatic patients who underwent the Immediate Complete Anterior Guidance Development (ICAGD) coronoplasty. This computer-guided occlusal adjustment eliminated pretreatment FDH symptomatology, further supporting that Dentinal Hypersensitivity has an occlusally-based, frictional etiology.

Texte intégralRésumé :
The human (and mammalian) facial skeleton is a complex response to the protection, support, and functional demands of a diversity of neurological and physiological processes that must be structurally integrated, and each places limitations on the others. The processes involve respiration (nasal and oral) and mastication (and deglutition), as well as thermoregulation through respiration. Three of the special senses (vision, smell, and taste) are housed within the facial skeleton, although only the first has a major impact on the shape and structure of the facial skeleton. The challenge in assessing the facial configurations of the Sunghir human remains is to partition the facial skeleton in a paleobiologically meaningful manner. Traditionally in paleoanthropology, often given differential paleontological preservation, the facial skeleton is divided initially into its two major skeletal components (cranial and mandibular). The former is then assessed in terms of structures or individual bones, with variable focus on the configurations of the orbital, nasal, and palatal regions. The latter is evaluated as a whole or divided into corporeal and ramal regions. A more meaningful approach, although still one with its limitations, is to assess the face in terms of the three major functional units of the facial anatomy: the orbital, nasal, and masticatory units. Developmentally, in simplified terms, these units are sequential in their priorities. Even though the anterior orbital margins continue to grow anteriorly with facial growth through adolescence, their internal structure is formed early, given that the ocular sphere is an extension of the brain stem and grows in concert with it. The nasal region, both the internal capsule and its skeletal aperture, forms the core of the midface, the roof of the oral cavity, the medial surfaces for the zygomatic regions, and the baseline minimum for the length of the face given that the anterior mammalian dentition cannot be posterior of the nasal aperture. The maxillary dentition with its supporting structures is hafted onto the nasal capsule through the maxillary alveolar process, and the mandible normally grows to provide proper occlusion with the forwardly displaced maxillary dentition.

Texte intégralRésumé :
Smile with beautiful natural teeth is one of the greatest assets of a person. Untreated fractured teeth can affect day to day activities of children in school which can have a psychological impact on children. Apart from dental caries and periodontal diseases, a traumatic dental injury is the third most common cause of tooth loss. Violence, accidents, falls and sport-related activities are the leading causes of traumatic dental injuries, that majorly involve anterior teeth. Epidemiological studies indicate that dental trauma is a significant problem in young people and that soon, it will be a major dental health care requirement. Prevalence of traumatic dental injury in primary and permanent dentition ranges from 9.4-41.6% and 1% to 58.6%, respectively. The management of traumatic injuries to anterior teeth is also changing with advances in materials sciences and understanding of the mechanism of traumatic injuries.

Texte intégralRésumé :
This overview of the volume’s chapters focuses on intentional modifications of teeth, specifically alterations of crown shape or removal, as known from historical and ethnographic sources, archaeological studies, and observations of contemporary peoples. Anterior teeth, a highly visible aspect of a person’s appearance, were altered for different reasons by past and present peoples. While purposeful modifications of the dentition are of principal interest, they must be distinguished from features that can mimic them, including use wear, pathological features, and decay or trauma-related tooth loss.
