Introduction

Various forms of malocclusion are a matter of serious concern in Nepalese population. This study was carried out to understand the prevalence of malocclusion among the school children of Biratnagar. The objective of this research is to find out the prevalence of malocclusion of children from different schools of Biratnagar visiting the Pedodontics and Orthodontics department of Nobel Medical College and Teaching Hospital, Biratnagar. Result: Subjects with normal occlusion was found to be 39 % and with malocclusion was found to be 61%. Class I malocclusion (60%) and angles class II div I subjects (88.33%) were in majority of the total study population. Conclusion: The present study helps to determine the prevalence of malocclusion and need of orthodontic treatment for the school children of Biratnagar. The American Academy of Orthodontists (AAO) recommends that children should have an orthodontic examination by age 7 for two very good reasons. A consensus definition of early treatment holds it as treatment started in primary or mixed dentition to enhance the dental and skeletal development before the eruption of permanent dentition.[5]
