title: A comparative study of student vs supervisor diagnoses of anatomical abnormalities affecting the TMJ.
abstract: BACKGROUND
  The use of modern teaching methods and learning tools by educators to ensure competent graduates has been encouraged. At the Department of Odontology, University of Pretoria, School of Dentistry, four diagnostic screening tests were tested as learning tools and their efficacy in teaching undergraduate dental students to diagnose abnormalities affecting the osseous components and associated muscles of mastication of the temporomandibular joint (TMJ). These screening tests are known as joint play, end feel, static pain and dynamic pain.
  
  
  OBJECTIVE
  The aim of this study was to determine if dental students would be able to diagnose abnormalities affecting the osseous components and associated muscles of mastication of the TMJ using these four screening tests, as well as to compare their diagnoses with the diagnosis of a prosthodontist.
  
  
  METHODS
  One hundred joints were randomly examined for abnormalities by 50 dental students and a prosthodontist. The diagnoses were recorded on a diagnostic form and entered into an electronic Microsoft Excel database.
  
  
  RESULTS
  Of the 100 joints examined, 78 of the diagnoses made by the students were in agreement with that of the prosthodontist, which is highly significant (p < 0.001).
  
  
  CONCLUSIONS
  The tests were used successfully by the majority of the students to make a correct diagnosis.
