Objective: The aim was to compare Rosenberg self-esteem scale (RSES), sensitivity to criticism scale (STCS) and social appearance anxiety scale (SAAS) scores of individuals with different types of malocclusions, and investigate the correlation between these scores and the index of complexity, outcome and need (ICON) score.
Materials and methods: One hundred and twenty individuals, who did not have any previous orthodontic treatment, were included. Group 1 included 40 patients with Class I malocclusion (median age of 14 years), Group 2 included 40 patients with Class II malocclusion (median age of 14.25 years) and Group 3 included 40 patients with Class III malocclusion (median age of 15.15 years). ICON scores were 46, 53 and 56 for Groups 1, 2 and 3, respectively. RSES, STCS and SAAS questionnaires were performed to the patients. Student's t-test, one-way analysis of variance (ANOVA), Mann-Whitney's U and Kruskal-Wallis's tests were used for the statistical analysis.
Results: Group 1 showed significantly higher level of RSES scores compared to Groups 2 and 3 (p<.05). STCS scores were found to be significantly higher in Group 2, compared to other groups (p<.05). Group 1 (32.53 ± 8.94) showed significantly lower level of SAAS scores compared to Group 2 (39.63 ± 9.28) and Group 3 (39.42 ± 10.54) (p<.05). A significant positive correlation was found between the ICON and SAAS scores (r = 0.247, p=.007).
Conclusions: Adolescents with Class II and III malocclusions reported higher levels of social appearance anxiety scores, and lower levels of self-esteem scores compared to Class I. Complexity of orthodontic treatment need showed a significant impact on social appearance anxiety.
