Abstract
Objective: To determine the prevalence of malocclusion in school-age children from a selective area of the urban and rural community of Bangladesh. Methods: A cross-sectional descriptive survey was conducted among 748 children aged 08-12 years old were examined from October 2019 to September 2020 in Sylhet Sardar Upazila, Bangladesh. Angle”s classification was used for recording molar relationship with malocclusion traits. The study participants were examined by disposable dental tools (calibrated probs and mirror) including torchlight. After the collection of all data, it was compiled and analyzed by Statistical Package for the Social Sciences (SPSS) Windows version 23. Chi-square test was used for categorical variables. P values <0.05 were considered as statistically significant. Result: The prevalence of malocclusion in urban school-age children was 237(63.4%) and in rural 213(57.0%).In urban area, the prevalence of malocclusion was 109(58.3%) in boys and 128(68.4%) in girls group. The majority (70.5%) were found Angle’s class I in urban group and 148(69.5%) in rural. One forty three (60.3%) patients were found increased overbite with malocclusion in urban group and 124(58.2%) in rural. Angle’s class-I malocclusion and Increased overbite were the most commonly occurring malocclusion. Conclusion: Prevalence of malocclusion was more in urban school age children when compared with rural. Malocclusion was significantly more in girls than boys in both urban and rural area. Angle’s class-I malocclusion and Increased overbite were the most commonly occurring malocclusion of school age children from a selected urban and rural community of Bangladesh. Update Dent.

Summary
Malocclusion as a word means bad bite[1]. Malocclusion can be defined as an occlusion in which there is a mal-relationship between the arches in any of the planes or where there are anomalies in tooth position, number, form, and developmental position of teeth beyond normal limits[2]. The term malocclusion is a derivative of occlusion which is the contact relationship between upper and lower teeth when the mouth is fully closed as well as the relationship of the teeth within the same jaw It may be primary which arise in the developing dentition or secondary, which arise in the adult as a result of tooth loss and consequent adjacent tooth movement[3]. Malocclusion ranks second among the common dental diseases in children and young adults, next to dental caries[5].Malocclusion is not a disease, but a developmental condition representing biological diversity It is basically the clinically significant variations from normal morphology and range of growth. The distinction in the commonness of malocclusion in boys and girls of two regions (rural and urban) was profoundly huge significant.The most common traits of malocclusion were Angle’s class I and overcrowding. Bangladesh being a developing country, there are still remote villages unaware of the advances in various fields; one such being
