Abstract:
Objective:To explore the influence of buccal corridor of Han people on smile esthetics.Methods:An attractive adult male and a adult female were selected as the models.Buccal corridor was altered digitally with slider technology of Adobe Flash CS4 to obtain a continuous range of buccal corridors(0% -25%).96 orthodontists aged 35.1 ±7.2 years and 96 laypersons aged 37.3 ± 5.1 years were chosen as the raters.The minimum tolerable value(A%),the ideal value(B%)and the maximum tolerable value (C%)of buccal corridor of the models were statistically analyzed.Results:In the orthodontist groupA,B and C of the male model were 5.00 ±0.1 7,9.75 ±2.77 and 1 5.00 ±2.84,in layperson group were 4.79 ±1 .00,9.20 ±3.08 and 1 5.05 ±2.91 ,respec-tively;in orthodontist group,A,B and C of the female model were 3.92 ±0.1 7,1 1 .87 ±2.77 and 1 5.82 ±2.84,in layperson group were 4.00 ±1 .00,1 2.05 ±3.08 and 1 5.1 1 ±2.91 ,respectively(all data between groups,P >0.05).The ideal buccal corri-dor value(%)of the male and female models were 9.48 ±2.73 and 1 1 .96 ±1 .99 respectively(P <0.05).Conclusion:There is no difference between orthodontists and laypersons for buccal corridor esthetic judgment.The ideal esthetic buccal corridor size of male and female is different.
