家庭口腔卫生行为与儿童龋齿危险因素的相关性研究

The relationship between familial oral hygiene behaviors and the caries risk factors in children

目的:对儿童的家庭口腔卫生行为变量与龋齿危险因素变量进行相关性研究,初步解释家庭口腔卫生行为对龋齿危险因素的影响机制,以便于确定今后龋齿预测模型中行为学变量的构成以及对口腔卫生行为进行针对性的指导。方法:通过问卷调查,获得样本的各行为学变量并据其分值对样本进行分组;测定各实验室指标并作一定的变量转换;使用SPSS12.0软件包中的独立样本t检验、多因素回归方程建立、相关及回归分析等统计学方法,探讨行为学变量与龋齿危险因素变量之间的关系。结果:①家庭口腔卫生行为与儿童的龋齿危险因素间存在显著相关性。②不同的家庭口腔卫生行为对龋齿危险因素影响的侧重点不尽相同。③儿童口腔卫生行为的获得除家长途径外,尚存在其他可能。结论:除熟知的龋齿危险因素外,在建立龋病预测模型时,应考虑加入各家庭口腔卫生行为变量。

PURPOSE： The aim of this study is to explore the relationship between familial oral hygiene behaviors and caries risk factors of children and to speculate the possible influential mechanism in order to predict the onset of caries accurately and thoroughly and guide the oral hygiene behaviors accordingly as well. METHOD： The behavioral variables were acquired through delivering questionnaires and then the children were grouped based on the outcome of questionnaires; the caries risk factors were made necessary transformation; the relationship between them were analyzed with SPSS12.0 software package for independent t test, stepwise logistic analysis, correlation and regression analysis. RESULTS： （1） Familial oral hygiene behaviors did influence the caries risk factors statistically. （2） Each kind of oral hygiene behavior had its special target caries risk factor and hence speculating its mechanism was different. （3）The oral hygiene behavior of children might be the result of a complicated influence of many factors including the parents, the teachers and other facets such as the media. CONCLUSION： Besides the conventional caries risk factors, the behavioral variables should be considered to be incorporated into the caries predict model.
