Relationship between occlusal factors and signs and symptoms of mandibular dysfunction. A clinical study of 48 dental students.

Forty-eight young adults answered a questionnaire and were examined clinically for determination of symptoms and signs of mandibular dysfunction in accordance with the Helkimo indices. Occlusal conditions recorded included contacts in centric and excentric mandibular positions in accordance with specified criteria for registration of "ideal occlusion', various occlusal patterns, occlusal interferences, and dental attrition. Relatively frequent but mainly mild signs and symptoms of mandibular dysfunction were found. The occlusal conditions were extremely varied and did not show any significant correlations with signs and symptoms of mandibular dysfunction.
