ABSTRACT

A presença de dentes supranumerários pode causar alterações funcionais e estéticas, principalmente quando localizados na região anterior da maxila, contando, ainda, com complicações na erupção do elemento dental permanente da área afetada. São definidos como dentes de desenvolvimento anormal que podem ocorrer tanto na dentição decídua como na dentição permanente, podendo ser únicos ou múltiplos, uni ou bilaterais permanecer impactados ou erupcionar na cavidade bucal e a sua etiologia permanece ainda desconhecida. A prevalência varia entre 0,8% e 3,7%, em diferentes estudos apresentados, sendo que o sexo masculino é o gênero mais prevalente. Frequentemente eles são diagnosticados em exames de rotina, uma vez que, na maior parte dos casos, são assintomáticos. Quando diagnosticados, a remoção cirúrgica está indicada para que o mesmo não venha causar interferência na dentição permanente. Este artigo apresenta o relato do caso de uma criança de 08 anos de idade que apresentava um dente supranumerário na região dos incisivos centrais superiores e o tratamento realizado foi a exodontia e, posteriormente, tratamento ortodôntico preventivo


The occurence of supernumerary teeth can cause functional and aesthetic changes, particularly when located in the anterior maxilla, as well as complications in the eruption of permanent dental element in the affected area. Such term is defined as abnormal teeth development that may occur either in the primary dentition or in permanent dentition. They can be single or multiple; unilateral or bilateral; remain impacted or erupt in the oral cavity and its etiology remains unknown. The prevalence varies between 0.8% and 3.7% in different studies, and the male is the most prevalent gender. Often they are diagnosed during routine examinations, and are asymptomatic in the majority of the cases. When diagnosed, removal surgery is indicated in order to remove any interference in the permanent dentition. This article presents a case report of a 8 years old patient who presented a mesiodens between upper central incisors and was treated by tooth extraction followed by preventive orthodontic treatment

ABSTRACT

The purposes of this study were to investigate radiographically the dental and maxillomandibular in patients with neuropsychomotor disorders and determine the role of panoramic radiographs for quantitative and qualitative analyses of dental alterations. A total of 322 panoramic radiographs from 190 males and 132 females aged 4 to 57 years were obtained from the files of the Center for Care to Patients with Special Needs (CAPE; Dental School, University of São Paulo) and subdivided into syndromes, special needs, neurological, neuromuscular or cerebral disorders, and sequels of diseases. 32 percent of dental alterations were in tooth position, with 69 percent of this group associated with tooth rotation. The mandible accounted for 54.62 percent of alterations. The male gender (55.85 percent) and the permanent dentition (78.7 percent) were most affected. Panoramic radiographs were proved to be well suited for quantitative evaluation of dental anomalies of epidemiological nature. Panoramic radiographs are important diagnostic resources when applied to patients with special needs because of the difficulty to place intraoral films and held them correctly positioned during the radiographic technique.
