Detection of bifid mandibular condyle by panoramic radiography and cone beam computed tomography

Abstract

Aim: To compare panoramic radiography and cone beam computed tomography (CBCT) in the diagnosis of bifid mandibular condyle. Methods: The sample consisted of 350 individuals who underwent panoramic radiography and CBCT. In the panoramic radiographs and CBCT images, the presence or absence of bifid mandibular condyle was determined. Results: Presence of bifid mandibular condyle was detected in four cases (1.1%). In all cases, the relation of one condylar process to the other was mediolateral and history of trauma was reported. None of the individuals had symptoms. In two cases, panoramic radiography did not reveal the presence of bifid mandibular condyle. Conclusions: Initial screening for bifid mandibular condyle can be performed by panoramic radiography; however, CBCT images can reveal morphological changes and the exact orientation of the condyle heads.
