| This study aimed at collecting data of masseter myofascial tension, related to the joint hyperactivity by electromyography activity of masseter muscle at rest, isotonic and isometric chewing. 08 patients living in the city of Buenos Aires, Argentina, volunteers, aged between 22 and 62 years, both sexes were evaluated. The electromyography data collection at rest had reported that 50% showed differences in masseter muscle tension increased in the left for the right masseter; in isometric contraction, 50% had a difference in masseter tension right; in isotonic contraction 62.5% there was a difference in increased tension in the left masseter. Anthropometry of the face was suggested, where 25% showed significant variance of 01 cm of discrepancy on the right,... |

| The jaw muscles are essential components in the stomatognatic system. Their complex architecture allows them to execute several motor tasks. One of the structural peculiarities is the presence of hybrid and neonatal fibers.We studied the differences of the fiber-type in masseter and temporalis muscles along the first to nineth decades in both genders. Seventy-four (74) samples were analyzed by immunohistochemistry. Slow and fast muscle fibers distribution was similar in both muscles in both genders. Hybrid fiber was observed in all decades, and its frequency decreased significantly (p<0.001) with aging in masseter. Neonatal myosin expression was observed in all decades, its expression was more frequent in masseter (p=0.01), and males in temporalis... |
