Popis: Objectives To determine the frequency, location, and shape of distomolar teeth in a population of urban Turkish adults. Methods A total of 4, 023 patients (1, 586 males, 2, 437 females) with a mean age of 32.85 ± 10.82 years (males 33.01 ± 11.39, females 32.76 ± 10.62) were studied. Patients younger than 18 years of age were excluded. Panoramic radiographs of the patients were examined to diagnose the presence of distomolar teeth. In the diagnosis, care was taken to include only those patients who had not undergone any extractions in the third molar regions. Data were analyzed by the chi-squared test (P < 0.05). Results The presence of distomolars was observed in 0.57% of this population. In total, 29 distomolar teeth were observed in 23 patients. Distomolars were found primarily in the maxillary left (n = 8, 27.5% of the distomolars) and right quadrants (n = 6, 20.6% of the distomolars). In one patient, they were observed in all four quadrants. Distomolars occured more frequently in the maxilla (n = 20, 68.9% of the distomolars), were often impacted (n = 20, 68.9% of the distomolars), and were found bilaterally in three cases (0.07%). © Japanese Society for Oral and Maxillofacial Radiology and Springer 2009.
