A Retrospective Study On Demographics and Characteristics of the Supernumerary Teeth in Western-Central Anatolian Region.

摘要

Objectives : Supernumerary teeth (ST) are impacted or erupted redundant teeth on normal primary or permanent dentition. The prevalence and type of ST may vary due to geography and ethnicity. In this study, demographics and characteristics of surgically operated supernumerary teeth in an institution in Western-Central Anatolia were evaluated. Materials and Methods: Computerized tomography or panoramic radiography images and clinical data of 67 supernumerary teeth that were surgically operated in a 1-year period was retrieved from archives and data regarding localization, age, type of ST were recorded. Results: The mean age was 15.89. Twenty-three (34.4%) of 67 ST were erupted and 44 (65.6%) of them were impacted. Four types of supernumerary teeth were identified. The most common form was conical form.(44.7%) Twenty-five (37.3%) ST were removed with related cyst enucleation. The most common localization was mandibular premolar region. (53.7%) Conclusions: All acquired data was consistent with the previous literature findings. Computerized tomography may be useful in the surgery of multiple ST cases.
