In order to find the difference between the habitual chewing side and the non-habitual chewing side during mastication, the 5th stroke to the 14th stroke of 20 normal subjects masticating chewing gum were analyzed using the automatic masticatory movement analyzing system, and the opening distance, average path, rhythm, and the stability of chewing path and rhythm were calculated and compared between the two sides. 1. The average path can be classified into 2 classes. Both the habitual and tlae non-habitual chewing sides showed similar pattern in almost all the subjects. 2. No significant differences were found in the opening distance between the habitual and non-habitual chewing sides. 3. There were significant differences in the stability of chewing path between the two sides with the non-habitual chewing side being less stable. 4. No significant differences were found in the chewing rhythm between the two sides. Though differences among individual subjects were found. 5. There were differences in the stability of chexving rhythm between the two sides in 14 out of 20 cases with the non-habitual chewing side being less stable. 6. It xvas recognized that the non-habitual chewing side is less stable than the habitual chewing side in both path and rhythm. Thus functionally the two sides differ.
