Many methods have been clinically applied for the occlusal analysis in the intercuspal position. However, none of these methods are quantitative. This study described the new software version of the T-Scan system to record and analyze occlusal contact balance in the anterior-posterior and right-left directions. Six time moment statistics and five force moment statistics were calculated in the midsagittal and the incisal axes of the occlusal plane. In the present study, informed consent was obtained from 60 subjects with natural dentitions and from two patients with craniomandibular disorders. In normal subjects, the time moments and the force moments of occlusal contacts were symmetrical about the midsagittal axis of occlusal plane. The location of the center of effort for the antero-posterior occlusal contacts, which was measured from the incisal axis of occlusal plane, was also in the first molar region. However, any of the above mentioned statistics was abnormal in the patients with craniomandibular disorders.

Abstract:This study was made to investigate the correlation between masticatory laterality, handedness and footedness in 1287 volunteers.The results obtained were as follows: 1. Right-biased chewing behaviour was slightly predominant in comparison with the other side.2. Handedness and footedness had no significant correlation with masticatory laterality. 3. It was showed that oral diseases and the treatments mainly motivated to be conscious of masticatory laterality. Dental caries, toothache and missing teeth tended to be determinant factors of acquired masticatory laterality.

This study was made to measure non-invasively the deep temperature of the tern
