Prevalence of class ii division 2 malocclusion and its associated factors-a retrospective study in a private dental hospital in Chennai, Tamilnadu

Abstract

Malocclusion is defined as the improper relationship of maxillary to mandibular teeth. Prevalence of the various types of maloc-clusion vary among different genders, races, ethnicities. Generally, genetics play a very important role in contributing to the same. Class II division 2 malocclusion is one of the lesser common types of malocclusion found in the population. The aim of our study is to analyse the association of class II division 2 malocclusion with gender, age groups and most commonly associated inter-arch and intra-arch malocclusions in the city of Chennai, a study performed in a private dental hospital. A retrospective analysis was done wherein patients’ intraoral photographs were checked for cross reference and Chi-square tests were performed. 108 patients were observed with Class II division 2 malocclusion out of which 58.3% were males and 41.7% were females. A higher prevalence of Class II division 2 malocclusion among males (p value>0.05) was observed and patients of age group 21-30 years were most commonly encountered in the clinic with Class II division 2 malocclusion (p value >0.05). Scissor bite (p value>0.05) was most commonly found as an associated malocclusion trait among these patients.
