摘要

目的:探讨12岁马来西亚马来学龄儿童的咬合特征、舌习惯、唇部能力及其性别二态性。材料和方法:方法涉及马来西亚雪兰莪州沙阿南公立学校208名受试者的临床检查。根据角度分类评估咬合状态。还评估并记录了以下特征:覆盖、覆盖咬合、外伤性覆盖咬合、拥挤、间距、中线间隙、交叉咬合、剪刀咬合、牙齿中线移位、犬齿移位、缺牙、外伤性断牙、舌推力和嘴唇能力。所有测量均采用描述性统计;采用卡方法评估性别差异。结果:男孩和女孩中I类错牙合发生率最高(分别为44.0%和43.8%),其次是III类错牙合(男孩31%,女孩30.4%)。69.7%的样本出现前牙拥挤,30.8%的样本出现前牙间距。不称职的嘴唇在男孩中比女孩更常见。结论:该年龄组错牙合的患病率可能需要在牙齿和口腔健康规划中采取更多的预防和拦截措施。

Occlusal Features of 12 Years Old Malaysian Malay Schoolchildren in Shah Alam
Objectives: To assess the occlusal features, tongue habits, lip competence and their gender dimorphism in 12 years old Malaysian Malay school-children. Materials and methods: The method involved clinical examination of 208 subjects from public schools in Shah Alam, Selangor, Malaysia. Occlusal status was assessed according to Angle classification. The following features were also assessed and recorded: overjet, overbite, traumatic overbite, crowding, spacing, midline diastema, cross bite, scissors bite, dental midline shifts, canine displacement, missing teeth, traumatically fractured teeth, tongue thrust and lip competence. Descriptive statistics were used for all measurements; Chi-square was used to assess gender differences. Results: Class I malocclusion is most prevalent in boys and girls (44.0% and 43.8% respectively), followed by Class III malocclusion (31% in boys and 30.4% in girls). Anterior crowding was found in 69.7% of the sample while anterior spacing was found in 30.8%. Incompetent lips were more common in boys than girls. Conclusions: The prevalence of malocclusion in this age group may warrant the need for more preventive and interceptive measures in dental and oral health planning.
