RESUMEN
Submersion is a clinical term describing a tooth depressed below the occlusal plane. In this case report, we present treatment of a patient who had totally submerged primary maxillary second molar, which caused impaction of the second premolar and space loss in the maxillary arch due to tipping of adjacent teeth. A 19 yr old female was referred to the Department of orthodontics. Intraoral examination revealed left mandibular second primary molar was localized lingually being almost covered by gingiva and adjacent teeth inclined closing the space of the related tooth completely. Panaromic radiograph demonstrated that mandibular second premolar was impacted. Based on clinical and radiographic findings mandibular primary second molar was extracted. A pre- Adjusted Edgewise appliance (MBT prescription 022” slot) was used for creating space for the impacted second premolar. Eruption began spontaneously 6 months later.
RESUMEN
Amelogenesis imperfecta (Al) is a diverse collection of inherited diseased that exhibit quantitative or qualitative tooth enamel defects in the absence of systemic manifestations. Also known by varied names such as Hereditary of enamel dysplasia, Hereditary brown enamel, Hereditary brown opalescent teeth, this defect is entirely ectodermal, since mesodermal components of the teeth are basically normal. The Al trait can be transmitted by either autosomal dominant, autosomal recessive, or X-linked modes of inheritance. It is necessary to diagnose the case and provide durable functional and esthetic management of these patients, where the unaesthetic appearance has a definite negative psychological impact.
RESUMEN
Congenitally missing teeth have been observed as one of the most common human dental developmental anomalies. In the permanent dentition the prevalence rate of true partial exodontias is 3.5% to 6.5%. The most likely factors of hypondontia are hereditary, environmental factors and evolution. Various studies have demonstrated differences in frequency and Patten between sexes, and in frequencies among the races. A case of eight congenitally missing teeth is presented.
