Abstract

Background: Orthodontic care globally urges the need to develop various methods to assess and grade malocclusion in order to prioritize treatment Objective: The purpose of the present study was to describe Angle’s molar relationship among the study subjects with the facial profile. Methodology: This study was designed as a Descriptive Cross-Sectional study carried out in four high schools in Dhaka city, Bangladesh. The study was conducted from May 2015 to November 2015 for a period of 06 (six) months on 384 secondary school children aged between 11 – 16 years Systematic Random Sampling from four high schools in Dhaka city.

In addition, trained research assistants were explained the study procedures. Results: Out of 384 children, the maximum no. of Angle’s molar relationship was Class I in both sides, similarly maximum no. of Canine relationships was Class I in both sides. Maximum face form was oval (51.8%), maximum (57.6%) face profile was straight and maximum (76.6%) lips were competent. Conclusion: In this study, malocclusion was 56.7%. Angle’s class I malocclusion is the most common while Angle’s class III is the least prevalent malocclusion. Journal of National Institute of Neurosciences Bangladesh, July 2022;8(2):206-209
