Abstract

The purpose of this study was to identify the functional profiles of occlusal disharmony associated with psychosomatic aspects in temporomandibular disorder patients. Thirteen female patients (with a mean age of 47.6 years) who complained of occlusal disturbances and/or occlusal instability caused by past dental treatment were examined before treatment. In addition to undergoing clinical examinations, all patients completed psychometric inventories (CMI, MAS). For functional examination, their occlusal contact areas, occlusal forces, and masseter asymmetry indices (AI) at 50% of maximal voluntary activity of bilateral masseters in the intercuspal position were measured. AI of the occlusal contact area and occlusal force were calculated for further analysis. Moreover, the ranges of tapping points at 4 Hz were quantified and evaluated. Relationships among these values were statistically analyzed.<BR>The results from CMI and MAS showed that 46.2% of the patients had neuroticism and 53.8% had manifest anxiety. Values of occlusal contact area, occlusal force, and each AI were not judged to reflect occlusal instability as a whole. Tapping points were significantly greater in the anteroposterior range (TPAP) than in lateral range (TP-LR)(p<0.05). Statistically significant correlations were found between manifest anxiety and TP-LR (p<0.005). This correlation suggested that manifest anxiety and TP-LR of these patients may influence each other.
