Abstract

Background: : Cross-bite is one of the most prevalent malocclusion. Objective: This study was an attempt to find out the prevalence of crossbite in Bangladeshi population and its variation with age and gender. Methodology: This cross-sectional study was conducted in the dental unit of Rajshahi Medical College, Rajshahi, Bangladesh from January, 2017 to December, 2018. Patients who were seeking comprehensive orthodontic treatment at the OPD of Rajshahi Medical College Dental Unit, Rajshahi, Bangladesh in between 5 to 35 years of age were diagnosed for cross-bite with diagnostic model. The findings of each cases was recorded in a preformed datasheet and the descriptive analysis was performed. Result: Out of 300 cases 163(54.3%) cases had cross-bite, 90(30%) cases had anterior cross-bite and 109(36.3%) cases had posterior cross bite. Among posterior crossbite 60(20%) had unilateral and 49(16.3%) had bilateral crossbite. Conclusion: Posterior crossbite was more prevalent than anterior crossbite. Cases with Class I molar relation showed more crossbite. Crossbite was more prevalent in cases with congenitally missing teeth Journal of National Institute of Neurosciences Bangladesh, 2019;5(2): 167-171

孟加拉国某牙科医院正畸患者交叉咬合的患病率

背景:交叉咬合是最常见的错牙合之一。目的:本研究旨在了解孟加拉人群中十字咬的患病率及其随年龄和性别的变化。方法:本横断面研究于2017年1月至2018年12月在孟加拉国拉杰沙希拉杰沙希医学院牙科单元进行。在孟加拉国拉杰沙希拉杰沙希医学院牙科科门诊寻求综合正畸治疗的患者年龄在5至35岁之间，通过诊断模型诊断为交叉咬合。每个病例的调查结果记录在一个预先形成的数据表中，并进行描述性分析。结果:300例患者中交叉咬合163例(54.3%)，前交叉咬合90例(30%)，后交叉咬合109例(36.3%)。单侧牙合60例(20%)，双侧牙合49例(16.3%)。结论:后牙合比前牙合多见。磨牙关系为I类的患者出现较多的交叉咬合。孟加拉国家神经科学研究所学报，2019;5(2):167-171
