- Abstract
Objective: To record prevalence of malocclusion among 2,400 adolescents in Karnataka state, India and to deine difference in malocclusion status in urban and rural population. Design: Randomized cross-sectional study. Setting: School students of Karnataka state, 24 August 2011 to 30 March 2012. Participants: School students in the age group of 13-17 years. Materials and Methods: Each individual was assessed for occlusal traits - sagittal occlusion, overjet, overbite, crowding, midline diastema, and crossbite. Statistical Analysis Used: Examinations were computerized and analyzed using Statistical Package for Social Sciences version 16. Chi-square test was used for computing statistical signiicance. Results: 87.79% of population had malocclusion. Out of which 89.45% had class I, 8.37% had class II, and 2.14% had class III malocclusion. Normal overjet and overbite was seen in 48.22 and 49.87% of subjects, respectively. Frequency of crowding was 58.12% and 15.43% of subjects had midline diastema. Anterior crossbite was present in 8.48% and posterior crossbite in 0.99%. Urban population had twice the class II sagittal occlusion, and increased overjet as compared to rural population. Conclusions: Malocclusion is widely spread among population of Karnataka state, with greater prevalence in urban population. Early exfoliation of deciduous teeth and reined diet can be considered as viable etiological factors.
