“…[4][5][6] An investigation of the association between infraocclusion and dental anomalies in the current sample is presented in a separate paper. 7 The prevalence of infraocclusion reported in the literature varies widely. Published studies include prevalences of 1.3% in 2,342 American school children of unspecified age; 8.9% in 1,059 Swedish children aged 3 to 12 years; and 24.8% in 1,530 Israeli children aged 2.5 to 13.5 years.…”

AbstractBackground: The reported prevalence of infraocclusion varies widely, reflecting differences in definitions and measurement/scoring approaches. Aims:This study aimed to quantify the prevalence and extent of infraocclusion in singletons and twins during the late mixed dentition stage of dental development using a new diagnostic imaging method and objective criteria. The study also aimed to determine any associations between infraocclusion and sex, arch type, arch side and tooth type.Design: Two samples were analysed; 1,454 panoramic radiographs of singletons and 270 dental models of twins. Both samples ranged in age from 8-11 years. Adobe Photoshop CS5 was used to measure the extent of infraocclusion. Repeatability tests showed systematic and random errors were small. Results:The prevalence in the maxilla was low (<1%), whereas the prevalence in the mandible was 22% in the singleton sample and 32% in the twin sample. The primary mandibular first molar was affected more often than the second molar. There was no significant difference in the expression between sexes or sides. Conclusion:A new technique for measuring infraocclusion has been d...

“…5,15,22 Several studies have also been carried out on pairs of monozygotic and dizygotic twins in order to demonstrate the contribution of genetics to the development of dentition and occlusion. 9,[12][13][14][15][16]23 In relation to the development of supernumerary teeth, some studies claim that their etiology is not yet fully elucidated, but they believe that they can be transmitted as an autosomal dominant trait lacking penetrance in some generations. 6,8,13 Corroborating with this thinking, results from recent studies attempt to elucidate some genes that may be directly related to the development of this anomaly.…”

Introduction: The multifactorial etiology of malocclusion involves several factors such as genetic, epigenetic and environmental factors. Among various dental anomalies, the development of supernumerary teeth is also directly related to genetic factors and mesiodens is the most frequent type of anomaly. Case Report: Two monozygotic twin sisters, both of which presented mesiodens, but only one with associated anterior open bite. Supernumerary removal was performed in the two sisters, and the anterior open bite was treated with the use of a fixed palatine grid. Results: The case was finished with proper occlusion and intercuspidation, contemplating facial and dental esthetics. Conclusion: Observing the possible differences that occur in pairs of monozygotic twins, it can be concluded that the development of malocclusions is associated with an interaction between genetic, epigenetic and environmental factors. Thus, the diagnosis and treatment of malocclusion should be individualized for each patient.

“…The prevalence of failure of eruption of FPMs has been reported as 0.01%. There is consideration of whether LR6 is suffering from delayed development masquerading as IFE, but there is no reported evidence of an association between infraocclusion and delayed dental development.…”
