Malocclusion, a common oral health problem in children, is associated with several contributing factors. This study aimed to investigate the prevalence of mixed dentition stage malocclusion and its contributing factors in Chinese Zhuang children aged 7-8 years.
Overall, 2,281 Zhuang children, about 7-8 years old, were randomly selected using a stratified whole-cluster sampling method from schools in counties in Northwestern Guangxi, China. The children were examined on-site for malocclusion and caries by trained dentists, and basic data on the children were collected using questionnaires, including age, sex, parental education, parental accompaniment, and children's knowledge of malocclusion and treatment needs. Data were analyzed using the chi-square test and logistic regression analysis.
The total prevalence of malocclusion in Zhuang children aged 7-8 years was 58.5%, with the highest prevalence of anterior crossbite tendency, and the prevalence of anterior crossbite and anterior edge-to-edge occlusion was 15.1% and 7.7%, respectively. This was followed by an anterior increased overjet of 13.3% and an inter-incisor spacing of 10.3%. The lowest prevalence was 2.7% for anterior open bite. Sex, parental accompaniment, parental education, and decayed, missing, and filled teeth of the first primary molar were factors that contributed to malocclusion in Zhuang children.
Malocclusion is a common oral problem among Zhuang children. Therefore, more attention must be paid to the intervention and prevention of malocclusion. The impact factors should be controlled as early as possible.
错牙合畸形是儿童常见的口腔健康问题，与多种促成因素有关。本研究旨在调查中国7-8岁壮族儿童混合牙列期错牙合畸形的患病率及其促成因素。
采用分层整群抽样方法，从中国广西西北部各县的学校中随机抽取了2281名7-8岁的壮族儿童。由经过培训的牙医对这些儿童进行现场错牙合畸形和龋齿检查，并通过问卷收集儿童的基本数据，包括年龄、性别、父母教育程度、父母陪伴情况以及儿童对错牙合畸形和治疗需求的了解。数据采用卡方检验和逻辑回归分析。
7-8岁壮族儿童错牙合畸形的总患病率为58.5%，其中前牙反牙合倾向的患病率最高，前牙反牙合和前牙对刃牙合的患病率分别为15.1%和7.7%。其次是前牙深覆盖13.3%和牙间隙10.3%。前牙开牙合的患病率最低，为2.7%。性别、父母陪伴情况、父母教育程度以及第一乳磨牙的龋失补牙数是壮族儿童错牙合畸形的促成因素。
错牙合畸形是壮族儿童常见的口腔问题。因此，必须更加重视错牙合畸形的干预和预防。应尽早控制影响因素。
