Recent studies have shown that there are significant increasing facial asymmetry using 3-dimensional imaging. This study use panorama view and PA cephalograph that were low in price and make good use in dentistry.
For this study, 35 persons without remarkable malocclusion were selected, they had panorama view and PA cephalograph, make written questionnaire about facial asymmetry cognition and masticatory pattern. Data obtained were statistically processed by the SPSS Windows program and the results of this study were as follows:
1. There were significant difference between Rt and Lt. on Co-Go, Co-Ag, Co-Go-Ag, Go-Me- Ag.
2. In panorama view, There were significant difference between Rt. and Lt Co-Ag that chewing right side, Rt. and Lt. Co-Go that chewing left side,
3. In PA cephalograph view, There were significant difference in Rt. and Lt. Cg-Go, Rt. and Lt. Co-Ag that chewing right side, Rt. and Lt. Cg-Go that chewing left side
4. There were significant difference in Rt. and Lt. Co-Go, CO-si-CR, go-ME-Ag that cogniting facial asymmetry.
