The Evaluation of the Electrical Activity of the Chewing Muscles
Mimoza Canga MD PhD  | Vito Antonio Malagnino MD DDS 
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, 84.7 % for Masseter muscle, mean POC value was 85, 75 %, 124, 3V/V. s % was the activity of Temporal muscle and 96, 4 V/V. s %was the activity of Masseter muscle, 109, 8V/V. s % mean activity. In the second group the mean values were85, 38 % POC for Temporal muscle, 85, 85 % POC for Masseter muscle, 85, 61 % mean POC.89, 20 V/V. s % was the value of activity of Temporal muscle, 74, 90 V/V. s % was the value of activity of masseter muscle and 82, 05 V/V. s % was the mean value of both muscles. Conclussions The results of this study prove the sistematic influence of the occulsal contacts on the activity of the chewing muscles during contraction.
