【摘要】 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。更多还原

【Abstract】 OBJECTIVE The purpose is to investigate incidence of caries and unilateral mastication in adolescents, and to analyze the relationship between unilateral mastication and caries. METHODS By means of standard dental caries detection, unilateral mastication examination and questionnaire survey in students (160) among three junior middle schools in Chengdu, we analyzed the correlation between unilateral mastication and prevalence of dental caries. RESULTS According to the statistics,students with unilateral mastication had a 60.71% caries prevalence which was significantly higher than that of control group (40.68%). There was a significant positive correlation between unilateral mastication and dental caries prevalence (Phi = 0.198,P = 0.018). CONCLUSION Unilateral mastication and caries have a certain relevance, adolescents in Chengdu (14-15 year-old middle school students) with unilateral mastication have higher caries prevalence than that of none-unilateral-mastication. In the prevention of dental caries, the significance of preventing unilateral mastication should be highly valued.更多还原
