Objectives To investigate the frequency, prevalence, distribution, sex differences and characteristics of supernumerary teeth in a referred non-syndromic Turkish population. Methods A total of 5200 panoramic radiographs of patients who presented at the Department of Oral and Maxillofacial Radiology from July 2008 to August 2010 were evaluated. Demographic variables (age and sex), location, morphology, classification, number of supernumerary teeth, distribution, side and eruption status of supernumerary teeth as well as the management approach were evaluated for each patient with supernumerary teeth. Complications and pathological conditions were also recorded. Results Among the 5200 patients, 116 supernumerary teeth were found in 83 patients. These 83 patients comprised 48 males and 35 females, giving a ratio of 1.4:1. The average number of impacted teeth per person was 1.4. Parapremolar teeth (43.1%) were the most frequently observed supernumerary teeth, followed by distomolar teeth (31%), mesiodens (19.8%), paramolar teeth (2.6%), lateral incisors (2.6%) and canines (0.9%). Conclusion Supernumerary teeth had a prevalence of 1.6%, with parapremolar teeth being the most common supernumerary teeth in a Turkish population.
