There is a multitude of classifications based upon the aetiology, clinical signs and symptoms, or anatomy; all have their weaknesses. Those classification systems that define the different kinds of TMD and utilize the history and examination provide the most help to the general dental practitioner as well as to the researcher.

This is a dual axis classification of TMD pain in a research tool which aims to provide a more rational, scientific basis for TMD diagnosis.

 Axis 1: a set of opertionalised RDC for use in evaluating and investigating masticatory muscle pain, DD and degenerative diseases of the TMJ.
