Abstract
Objective:To investigate psychosocial impacts of malocclusion on junior high school students. Method:Nine classes were randomly sampled from the only two junior high schools in Wujiaqu city. There were 390 junior high school students(193 boys,197 girls). They are all Han people with mean age of 14.08±0.84 years,age range of 11.49~16.55 years. And they were assigned to the five groups through clinical assessment according to Incisor Classification and individ-ual normal occlusion criterion. The five groups represented were individual normal occlusion as well as incisor Class I,Class II/1,Class II/2,Class III malocclusion and individual normal occlusion group. Then, psychosocial impacts were assessed using Psychosocial Impact of Dental Aesthetics Questionnaire among all the subjects. Statistical analysis involved Kruskal-Wallis H test. Result:In terms of social impact,after comparing the other 4 groups with incisor class III group,there was statistical significance(P<0.0125) between incisor class III group and individual normal occlusion group. There was no sta-tistical significance (P>0.0125) between incisor class III group and the other 3 groups. Incisor class III group was 4 points higher than individual normal occlusion group. In terms of aesthetic concern, after comparing the other 4 groups with incisor class III group,there was no statistical significance (P>0.0125) between incisor class III group and incisor class II/1 group. There wasstatistical significance(P<0.0125) between incisor class III group and the other 3 groups. Incisor class III group was 3 points higher than incisor class I group,2.5 points higher than incisor class II/2 group,4 points higher than individual normal occlusion group. In terms of dental self-confidence, after comparing the other 4 groups with incisor class III group,there was statistical significance (P<0.0125) between incisor class III group and individual normal occlusion group. There was no statistical significance(P>0.0125) between incisor class III group and the other 3 groups. Incisor class III group was 4 points lower than individual normal occlusion group. Conclusion:Malocclusion has a certain adverse impact on social psychology of junior middle school students. Especially malocclusion increased their social impact,reduced their dental self-confidence,incisor class II 1 and incisor class III increased their aesthetic concern impact. The effect of incisor class II 1 on female social impact and aesthetic attitude was more serious, the effect of incisor class III on female aesthetic attitude is more serious,men in incisor class II2 group were more confident of their teeth than women. Encourage junior mid-dle school students with malocclusion to receive orthodontic treatment as soon as possible,give guidance and intervention to the psychological problems that may occur in time.关键词
