A supernumerary tooth is one that is additional. The diagnosis is usually made by clinical exam and routine radiographs, and the majority of such teeth are impacted and asymptomatic, without affect others teeth. The supernumerary teeth, can occur included or impacted. An early diagnosis is important in order to implement a suitable plan of treatment and prevent such complications. Ectopic inclusions occur at about 1% of the general population and might be present at many diverse localizations. In this article the authors review the literature around the ectopic inclusions and report a case of an intranasal ectopic supernumerary inclusion. The prophylactic surgical removal of the supernumerary teeth is generally the treatment of choice.
Dentigerous cyst, ranked the second most common developmental odontogenic cyst of the jaws after the radicular cyst, is a well-defined, unilocular radiolucent lesion without symptoms, frequently noted as an incidental finding in routine radiographs. The cystic lining is derived from epithelial remanants of the tooth-forming organ and the teeth most commonly affected are impacted mandibular third molars and permanent maxillary canines. While the dentigerous cyst is not uncommon, its development as a result of an impacted deciduous tooth is rare. The aim of this article was to make a brief literature review and report a case of dentigerous cysts associated with an impacted deciduous molar in the maxillary posterior region, with involvement of the right maxillary sinus.
RESUMOCaninos são elementos dentários importantes no que se refere a função, oclusão, estética. Distúrbios na erupção de caninos superiores permanentes são comuns. A erupção ectópica de um germe dentário pode ocorrer a qualquer momento, desde a sua erupção. Verificase ainda, que caninos superiores são mais acometidos com distúrbios de erupção que os terceiros molares. Diagnósticos de elementos dentários retidos são realizados por meio de exames clínicos e radiográficos, ou através de investigações de queixas diversas, como dor ou ortodônticas. O Cirurgião-Dentista deve estar familiarizado com as alterações funcionais e anatômicas referentes as impactações, ectopias dentárias e suas possíveis repercussões ao paciente, pois recomendações sobre as decisões a serem seguidas nos casos de impactações de caninos são determinadas através de minucioso estudo de cada caso. O objetivo do presente artigo é relatar um raro caso de canino incluso com proximidade da órbita.Termos de indexação: Dente canino. Cirurgia bucal. Dente não erupcionado.
