Abstract

The purposes of this research were to discuss changes in the smile after orthodontic treatment and to find the factors affecting smile changes during orthodontic treatment. Pre- and post-treatment frontal smile pictures and lateral cephalometric records were collected from 90 case files of the Specialists Examination of the Taiwan Association of Orthodontists. Pre-and post-treatment smile pictures were coordinated and measured with Adobe Photoshop 4.0 using a personal computer. Seven percentage measurements and fourteen cephalometric measurements were made from all collected pictures and cephalometric tracings, respectively. The post-treatment measurements were subtracted from pretreatment measurements to represent treatment changes in the smile and craniofaciadental morphology. t-test, ANOVA, and Pearson's correlation analysis were used to compare the correlation of the smile and craniofaciadental morphologies between pre- and post-treatment. The results showed that (1) there were no correlations among gender, malocclusion, extraction type, and smile changes; (2) there was a significant statistical difference (p<0.05) between the skeletal type (and age) and some smile changes; and (3) from the cephalometric measurements, U1-SN and U1-NA were significantly correlated with some smile changes (all p<0.05). In conclusion, orthodontic treatments can improve the smile; however, a scientific and objective method to evaluate smile changes still needs to be developed.
