Abstract:
The aim of the study was to evaluate the relation between the teeth occlusion and electrical activity of the chewing muscles.
Materials and method: The analyzed sample included 40 adult healthy patients 20 males and 20 females 20-40 years old, mean age 30 years old.
Results: We calculated the mean values of the number of teeth contact for each group. The first group had a contact number =241, the second group 126. Excluding the second molars, there was a uniform distribution in the posterior section. 20% of the contact of the first group and 24.6% of the second group were in the first molars, 22% and 19.8% respectively were in premolars. The POC was estimated for each patient. In the first group the mean values were: 86,80 % for Temporal muscle(DS=3.1), 84.7% for Masseter muscle(DS=3.5), mean POC value was 85,75%(DS=3.3); 124,3µV/µV .s % was the activity of Temporal muscle(DS=30.03) and 96,4 µV/µV.s % was the activity of Masseter muscle(DS=33.51), 109,8µV/µV.s% mean activity(DS=31.33). In the second group the mean values were85,38% POC for Temporal muscle(DS=3.1), 85,85 % POC for Masseter muscle(DS=5.7), 85,61 % mean POC(DS=4.4). 89,20 µV/µV.s% was the value of activity of Temporal muscle(DS=16.8), 74,90 µV/µV.s% was the value of activity of masseter muscle(DS=24.1) and 82,05 µV/µV.s% was the mean value of both muscles(DS=20.45).
Conclussions: The results of this study prove the sistematic influence of the occulsal contacts on the activity of the chewing muscles during contraction.
