Abstract
The purpose of this study was to investigate the variations of occlusal contact pattern according to chewing side preference. The author selected 59 dental students (mean age 2 3.6 years) who had no signs and symptoms of masticatory disorders and divided into two groups, that is, bilateral chewing side group and unilateral chewing side group, respectively.
For recording, T-Scan System(Tekscan Inc., U.S.A.) was used and the recorded occlusal contacts were examined as to the number of occlusal contacts, points distribution in dental arch, time sequence and force snapshot.
The obtained results were as follows
1. Total number of occlusal contacts were more in unilateral chewing side group and there were significant difference in number between right and left side or between chewing and less chewing side in all two groups.
2. All items related to time sequence showed no statistical significant difference between two groups in any case.
3. Unilateral chewing side group had more occlusal contact force than bilateral group, especially in chewing side.
From the above findings, the author considered that there was occlusal unbalance in unilateral chewing side group.
4. Chewing side preference would possibly have more effects on the occurrence rate of anterior tooth contact that the rate of prolonged thire contact but not proved.
