Cone-beam computed tomography evaluation of bifid mandibular canal in a Turkish population

Abstract

Aim: The aim of the study was to examine the prevalence of bifidmandibular canals (BMC) in a Turkish population, using cone-beamcomputed tomography (CBCT).Methodology: The CBCT images of 350 untreated patients (178male, 172 female ranging in age between 18 and 65,) were includedin this study. The presence or absence of BMC was determined in axial,sagittal, and coronal planes by considering gender and side. Forstatistical evaluation, a chi‑square test was used to determine anydifferences in the prevalence of BMC with significance set at 5%.Results: BMCs were observed in 129 out of 700 sides (18.42%) and 97out of 350 patients (27.71%), of which, 55 were in males and 42 infemales. Regardless of gender, the right side was more frequentlyaffected (73%). Male patients showed higher prevalence (15.71%) thanthe female patients (12%).Conclusions: BMC was observed in 27.71% of examined Turkishsubjects and detected more frequently in males and on the right side.
