摘要

背景:全球正畸护理迫切需要发展各种方法来评估和分级错牙合,以便优先治疗目的:本研究的目的是描述研究对象与面部轮廓的角度磨牙关系。方法:本研究设计为描述性横断面研究,在孟加拉国达卡市的四所高中进行。该研究于2015年5月至2015年11月进行,为期06(6)个月,对来自达卡市四所高中的384名11 - 16岁的中学生进行了系统随机抽样。参与者包括以前没有进行过预防性和拦截性正畸治疗的参与者和晚期混合恒牙或早期恒牙的参与者。排除有重大局部问题的学生,如创伤或任何影响面部结构或身体生长发育的手术史,正在接受正畸治疗或较早完成正畸治疗的学生,患有全身性疾病的学生。使用预先编制的数据收集表收集数据。收集并记录这些患者的相关社会人口学资料。收集数据并向家长/监护人提供研究描述、知情同意书(孟加拉文)和家族史/生活方式问卷(英文)。此外,还向经过培训的研究助理解释了研究程序。结果:384例患儿中;双方的摩尔关系均为I类,也有相似的最大值。狗的关系在双方都是第一类。最大脸型为椭圆形(51.8%),最大脸型为直型(57.6%),最大嘴唇型(76.6%)。结论:本组错牙合发生率为56.7%。Angle的I类错颌是最常见的,而Angle的III类错颌是最不常见的。孟加拉国国家神经科学研究所杂志,2022年7月;8(2):206-209

Relationship of Angle’s Molar Malocclusion with Facial Profile among School Children with the Age Group of 11 to 16 Years at Dhaka City in Bangladesh
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. The participants were included who had no preventive and interceptive orthodontic treatment previously carried out and participants having late mixed or early permanent dentition. The participants were excluded participants having major local problems such as trauma or any history of surgical approach which affects the growth and development of facial structures or body, Students who are undergoing orthodontic treatment or who have completed orthodontic treatment earlier, Students who are suffering from any systemic disease. Data were collected using a preformed data collection sheet. The relevant socio-demographic data of these patients were collected and recorded. Data were collected and Parents/ guardians were provided with a description of the study, an informed consent form (written in Bengali) and a family history/ lifestyle questionnaire (written in English). 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
