Abstract　： [Abstract] The condylar sizes in Japanese, Korean, and Egyptian individuals were compared using cone-beam computed tomography (CBCT). CBCT was used to measure the condylar sizes of 406 participants (179 Japanese individuals, mean age: 27.4 +- 8.7 years; 71 Korean individuals, mean age: 25.3 +- 6.4 years; and 156 Egyptian individuals, mean age: 24.2 +- 5.1 years) who visited or were recruited at medical institutions in their respective countries. Condylar size (length, height, and width) was measured using Invivo 5(TM) Anatomy imaging software and compared among the ethnic groups. The condylar length of Japanese participants was significantly larger than those of the other ethnic groups, while the condylar height of Korean participants was significantly higher than those of the other ethnic groups. Significant differences were not observed in the condylar width among the ethnic groups. The Egyptian condyle tended to be smaller than the condyles in other ethnic groups. Ethnic differences were noted in a comparison of condylar sizes among Japanese, Korean, and Egyptian participants.
