KONİK IŞINLI BİLGİSAYARLI TOMOGRAFİ KULLANARAK STAFNE KEMİK KAVİTELERİNİN PREVALANSININ VE ÖZELLİKLERİNİN ARAŞTIRILMASI: RETROSPEKTİF BİR ÇALIŞMA

Objective :  Stafne bone defects (SBDs) are asymptomatic radiolucent cavities usually located between mandibular angle and the third molar, below the inferior alveolar canal and above the basis of the mandible. The aim of this retrospective study is to estimate the frequency, age and sex distrubution and types of SBDs from Cone Beam Computed Tomography (CBCT) images of 169 subjects. Material and Methods :  CBCT images between the years 2014 and 2016 were obtained in Bolu Izzet Baysal University, Dentistry Faculty by using I-CAT 3D Imaging System from 169 subjects and analysed by one observer by utilizing axial, sagittal, cross-sectional, panoramic images and 3D reconstructions. Results :  Results of this study showed that SBDs frequency was 3.5% with the mean age of 51. Detected SBDs patients were all male. All cases were asymptomatic and unilateral. Conclusion :  Although the radiological appearance of the SBDs is usually pathognomonic, in indeterminate cases 3 dimensional examination as CBCT is recommended.
