Abstract
BACKGROUND: It has been assumed that clicking of the temporomandibular joint (TMJ) may predispose to closed locking. Although jaw clicking is a common complaint, locking of the TMJ is rare. METHODS: To assess whether clicking is a reliable predictor of locking, we examined longitudinally over 9 years the variation of reported and recorded TMJ clicking in 128 young Finnish adults. Subjects were interviewed and examined at the ages of 14, 15, 18, and 23 years. FINDINGS: Reported and recorded TMJ clicking both increased significantly with age, varying from 11% to 31% and from 11% to 34%, respectively, However, clicking showed no predictable pattern, and only a few subjects consistently reported clicking (2%) or had it recorded (2%). None developed locking. INTERPRETATION: Because none of the young adults developed locking of the TMJ, we suggest treatment for clicking should be conservative.
