Abstrakt:	Background: Few studies have investigated the volumetric relationship between the condyles and the mandible bilaterally. Materials and Methods: Condylar and mandibular segmentations from a sample of cone-beam computed tomography for 37 individuals were selected. T-test, correlation and linear regression analyses were performed to assess the relationships between the volumes of the condyles and mandible. Results: The volume of the condyles and the mandible was significantly different between genders (p < 0.05). There was a significant but moderate correlation between the volumes of the condyle and the rest of the mandible on the same side (p < 0.01). A regression analysis model demonstrated that condylar volume is related to the volume of the mandible. Conclusions: The relationship between the condylar volume and the rest of the mandible was found to be moderate. The relation between the condylar volume and mandibular volume is described by the regression equations for each side of the jaw. Sexual dimorphism exists in condylar and mandibular volumes.
