• Using normalized electromyogram(EMG)linear envelopes, I investigated the efffect of aging on the activity patterns of masticatory muscles and studied the factors causing these effects.EMG signals were recorded from the bilateral masseter and anterior temporal muscles during mastication of nine different foods.Although the activity patterns changed in the dentate subjects with the different foods, there was little change in those of the complete denture wearers during mastication of various foods.Factor analysis indicated that the teeth were the most important factor in muscle activity patterns for all most all of the foods.These results suggest that although aging has little effect on the activity patterns of the masticatory muscles, the effect of tooth loss is considerable.
