目的调查成都市青少年偏侧咀嚼习惯患病率、患龋率,并探讨偏侧咀嚼和龋病的关系。方法对成都市3所初级中学部分学生(160名)进行标准口腔龋齿检测、偏侧咀嚼检查及问卷调查,分析偏侧咀嚼者、龋病患病率二者之间的相关性。结果有偏侧咀嚼习惯时患龋率(60.71%)明显高于无偏侧咀嚼时患龋率(40.68%),偏侧咀嚼与龋齿患病之间显著正相关(Phi=0.198,P=0.018)。结论成都市青少年(14～15岁初中生)偏侧咀嚼者患龋率比非偏侧咀嚼者高,偏侧咀嚼和龋病存在一定相关性。在龋病预防发面,偏侧咀嚼的影响不可忽视。
Objective To investigate the prevalence and caries prevalence of unilateral chewing habits among adolescents in Chengdu and to explore the relationship between unilateral mastication and caries. Methods The standard oral caries test, unilateral chewing test and questionnaire survey were performed on some of the 160 junior middle school students in 3 junior high schools in Chengdu. The correlation between the prevalence of unilateral chewing and caries was analyzed. The results showed that caries prevalence (60.71%) was significantly higher than unilateral masticatory caries (40.68%) with unilateral masticatory habits, and positively correlated with unilateral chewing and caries (Phi = 0.198, P = 0.018 ). Conclusions The prevalence of caries in unilateral mastication of Chengdu adolescents (aged 14-15 years) is higher than that of unbiased mastication, and there is a certain correlation between mastication and caries in unilateral mastication. In the prevention of dental caries, unilateral chewing can not be ignored.
