Abstract

Objective: To assess the prevalence of malocclusion and deleterious oral habits among 12 and 15-year-old school children in Shimla city, India and to find, if any correlation exists between the two. Design: Correlational study design. Setting: Twelve schools in Shimla city, India. Materials and Methods: Prevalence of malocclusion and orthodontic treatment need was assessed using the Dental Aesthetic Index (DAI) among a sample of 961, 12 and 15-year-old school children in Shimla city, who received no orthodontic treatment before or during the study. Subjects were also assessed for deleterious oral habits. Statistical Analysis: Chi-square and Mann-Whitney U tests were used. Multivariate regression analysis was used to test the correlation of habits with mean DAI score and malocclusion traits. Results: Mean DAI score was 26.81±5.25. Nearly 53% of the study sample presented with malocclusion, ranging from ′definite′ to ′handicapping′ based on the DAI scores. The prevalence of various deleterious oral habits was 25.9%. About 29% of children with any oral habit developed malocclusion as compared to those without any habit (P value=0.023). Tongue thrusting, mouth breathing and thumb sucking habits had a significant impact on malocclusion. Conclusion: There was high prevalence of malocclusion (52.7%). Abnormal oral habits, particularly mouth breathing and tongue thrusting had a significant impact on malocclusion, resulting in higher frequency of crowding in anterior teeth, open bite, and spacing.
