DIFFERENCES OF CRANIOMANDIBULAR MUSCLE-ACTIVITY AND CERTAIN CEPHALOMETRIC PARAMETERS OF MANDIBLE BY SEX

The aim of this experimental study was to investigate masticatory musc le activity and some cephalometric data with special emphasis on sex d ifferences. The investigation was performed in two stages, In the firs t, electromyographic recordings of the temporalis and masseter muscles were examined and in the second stage the mandibular parameters such as angles of the mandible, length of the ramus and corpus of the mandi ble were measured. The results were statistically evaluated by one-way analysis of variance. Na statistically significant differences were o btained between males and females for electromyographic variables. For the cephalometric variables statistically significant difference at 9 5% level was obtained for the Length of the mandibular ramus.
