Evaluation of the Prevalence of Bifid Mandibular Condyle Detected on Cone Beam Computed Tomography Images in a Turkish Population

Abstract

SUMMARY:The aim of this study was to assess the frequency of the BMC phenomenon in a Turkish patient population. Cone beam computed tomography (CBCT) images of 2634 consecutive patients were retrospectively reviewed. The Chi-squared test was used to determine potential differences in the distribution of BMCs when stratified by sex and side. Among the 2634 patients, 42 (1.7%) patients were found to have BMC. Of these 42 patients, 22 were female (0.8%) and 20 were male (0.7%) with age ranging from 29 to 68 years (mean age 47.47). Among the 42 patients, 39 (92.8%) of the BMCs were unilateral and three (7.1%) were bilateral. Approximately 24 cases (53.3%) were on the right side, and 21 cases (46.6%) were on the left side. All of the BMCs showed a mediolateral orientation. The mean depth of the BMC was 2.55 mm in males and 2.68 mm in females. 2 patients have symptoms whereas the other patients were atraumatic and asymptomatic. BMC is a rare condition that might be more prevalent in the Turkish population. Greater detailed information regarding BMC could be obtained by the widespread use of CBCT in epidemiological studies.

Assessment of Condylar Shape through Digital Panoramic Radiograph among Nepalese Population: A Proposal for Classification

“…Bifid condyle can be detected by panoramic radiograph [18] but to our surprise the bifid condyle which could also have been considered/seen by other researchers as well. Although we agree that the prevalence of bifid condyle is very low (0.31-3.5%) [18][19][20][21][22][23], its real prevalence has not been predicted yet in our population.…”

“…BMK'nin simetrisiyle ilgili yayımlanmış vaka raporları ve sınırlı sayıdaki epidemiyolojik çalışma in- 13:1 şeklinde unilateral BMK lehinedir. 13,14,[18][19][20][21][22]25 Bu çalışmada da literatürdeki benzer çalışmalarla örtüşecek şekilde unilateral:bilateral BMK oranı 6:1 olarak bulundu. Bazı çalışmalarda, BMK'nin sol tarafta daha fazla gözlendiği bildirilmiştir.…”

Cone Beam Computed Tomographic Evaluation of the Mental Foramen Diameter: A retrospective study

“…6 Cone Beam Computed Tomography (CBCT) typically imposes a lower dose to patients compared to computed tomography. 7 There is not enough information about the diameter of MF in literature. Therefore, the aim of this study is to determine the Mental Foramen Diameter (MFD).…”
