The prevalence of bifid mandibular condyle detected in a Brazilian population

Dentomaxillofac Radiol. 2008 May;37(4):220-3. doi: 10.1259/dmfr/72314113.

Abstract

Objectives: To determine the prevalence of bifid mandibular condyle (BMC) detected on panoramic radiographs in a Brazilian population.

Methods: The panoramic radiographs of 50 080 radiographs taken from 1999 to 2006 were retrospectively reviewed in order to identify BMC cases.

Results: 9 (0.018%) of the 50 080 patients, 2 men and 7 women, with age ranging from 20 years to 74 years, had BMC. These conditions were unilateral in 7 (78%) subjects and bilateral in 2 (22%) subjects. All patients denied a history of any previous trauma or fracture of the mandible, pain, or trismus.

Conclusions: BMC is an uncommon finding in a group of Brazilian subjects and, although it is rare, dentists should be aware of this condition on routine panoramic radiographs and its implications for function and appropriate treatment modalities.
