The aetiology of temporomandibular disorders: A philosophical overview

Abstract

Over the last 50 years many theories have been put forward to explain the syndrome currently called 'temporomandibular disorders'. However, it is doubtful whether any single theory fits all the complex features of this condition. The 'multifactorial' explanation also appears flawed. On the assumption that a valid theory should fit the whole evidence, this paper starts by separating the 'predisposing' from the 'initiating' factors, and notes that most existing theories appear to identify the former rather than the latter. The research material is examined in an effort to formulate a theory that is both logical and fits all the known clinical findings.
