Luo D, Yang Z, Qiu C, et al. - Researchers conducted the study for analyzing the temporomandibular joint (TMJ) disc–condyle relationship in asymptomatic young adults. TMJ magnetic resonance imaging was performed on 93 volunteers aged 19–23 years who did not have temporomandibular disorder symptoms. Only 33.3% of the posterior edge of the articular discs were found to be in the normal 12 o'clock position relative to the condyle. Furthermore, this study suggests that the condylar centre method is less accurate than the condylar apex method in measuring the TMJ disc–condyle relationship. When compared with young men, the position of the articular disc (left and right) was more forward in young women. Although the two joint discs in the same individual were not completely symmetrical, there was no significant difference in TMJ disc–condyle position between the left and right sides in the same individual.
