Abstract
Objectives: The objective of the study was to evaluate the occlusal status of teenage patients and to determine the possible association of gender with the type of malocclusion. Materials and methods: The study sample consisted of 410 patients. Patients who did not fulfil the inclusion criteria for the study were excluded, thus the final sample accounted for 318. The selected subjects were interviewed by trained examiners and underwent thorough clinical evaluation pertaining to orthodontic diagnosis. Statistical analysis: The Pearson′s Chi-square test was done to assess the statistical significance between males and females while taking p-values of less than 0.001 as statistically significant. Results: Among the 318 samples, 166 (52.2%) of them were females and 152 (47.8%) were males. Angle′s class I molar relation was common (69.2%) followed by normal molar relation (10.1%), class III and its subdivision and class II and its subdivision were found common among males and females respectively. In regard to canine relationship, majority of them were class I followed by class II and III- Normal overjet and overbite was observed in 53.5% of the cases and there was higher incidence of increased overjet and overbite in females and reverse overjet in males Conclusion: The prevalence of malocclusion noted in the present study was 89-9% and it was more common in females. Class I canine relationship 96.9% was the most common one followed by class I molar relation (69.2%). Angle class II division 2; canine class III relationship and scissors bite were the least common (0.6%) occlusal alterations.
