Objective: To evaluate Angle's classification and Dental Aesthetic Index (DAI) among 12-15 year old school children and find the association between them. Methods: Sample consists of 400, 12-15 year old school children. Malocclusion prevalence, the severity of malocclusion and treatment requisite were evaluated to find the association between Angle's and DAI. Pearson Chi-square test was used for the comparison of categorical data. (P<0.05 was considered significant). Results: The percentage of children with DAI< 25 indicating little or no need for treatment was 65.5% and 12.8% had highly desirable or mandatory need fot treatment ie DAI>31. Among children with DAI< 25, a significantly high percentage of patients were in Class I (83.2%) whereas among children with DAI>31, higher percentage was noted in Class II/div 1 (29.2%) and Class III (28.6) than in Class 1(5.7) (P&?#60;0.001). Only 28.6% of children with Class III malocclusion were associated with appropriate DAI scores (>31) of severity and treatment need category. Conclusion: Only 12.75% of children had DAI score of > 31 suggesting highly desirable or mandatory orthodontic treatment requisite. DAI was not sensitive in terms of severity and treatment requisite criteria. Complimentary use of two methods seems to be feasible in all inclusive evaluation and care.
