ABSTRACT
Panoramic radiographs of a female patients aged twenty one years without any associated syndromic or systemic medical history, revealed the presence of the two supernumerary molars, right upper and left lower fourth molars. Both the teeth were disto-molars. The right upper fourth molar had normal tooth morphology with regard to its crown and root but was slightly smaller than the existing third molars. The left lower disto-molar had somewhat different morphology as compared to adjacent third molar and smaller in size as compared to the fourth right upper disto-molar. Their crowns were tuberculated and both had single root (2D radiographic morphology).
ABSTRACT
Os quartos molares são uma das anomalias de número mais frequentes, sendo encontrados commaior incidência na arcada superior, na dentição permanente e em pacientes do gênero masculino.A razão para esta anomalia dentária não está completamente elucidada, porém parece estar relacionadaa uma hiperatividade da lâmina dentária. O exame radiográfico consiste no elemento principalpara sua detecção, uma vez que se apresentam quase invariavelmente retidos e assintomáticos. Estetrabalho tem como objetivo relatar um caso de quartos molares superiores retidos bilateralmente,bem como comentar a sua etiologia, prevalência, descrição detalhada da técnica cirúrgica de remoção, complicações e forma de tratamento através de uma revisão bibliográfica.
Fourth molars are one of the most common number anomalies and are found with higher incidencein the maxilla, in the permanent dentition and in male patients. The reason for this dental anomaly isnot completely understood, but is probably related to hyperactivity of dental lamina. The radiographicexamination is the major element for diagnosis, since they have almost invariably retained andasymptomatic. This paper aims to report a case of upper impacted fourth molars bilaterally, as wellas comment on the etiology, prevalence, complications and treatment through a literature review.
