摘要
目的:分析乳牙集合菌斑中钙含量与儿童患龋状况的关系,为龋病预防研究提供基础资料。方法:应用原子吸收分光光度仪测定53例不同患龋状况的儿童集合菌斑中钙含量值。统计分析集合菌斑中钙含量值与龋病易感性的关系。结果:集合菌斑钙含量为(0.931±0.384)mg/g,菌斑钙含量无龋组、有龋组间差异有高度显著性P<0.01;无龋组、低危组、高危组间差异有显著性P<0.05,菌斑钙含量无龋组高于低危组,低危组高于高危组;有龋组集合菌斑中钙含量与龋补牙数(dft),龋补牙面数(dfs),龋蚀指数(CSI)具有负相关性。结论:集合菌斑中总钙含量与龋患程度具有一定的相关性,可为预测龋病易感性提供参考。
Objective： To investigate the relationship between calcium contents in whole plaque of primary teeth and the caries status of children. Methods： Calcium contents in whole plaque of 53 children with different caries experience was determined with atomic absorption spectrophotometer. The relationship between calcium content in whole plaque and caries experience was analyzed by SAS （6.12 version）. Results： The calcium content in whole plaque is 0.931 ＋ 0. 384mg/g, the calcium content of caries - free group is significantly higher than caries - positive group（ P 〈 0.01 ）, A statistical difference of calcium content in whole plaque was found among caries - free group, low - caries - risk group and high - caries - risk group（ P 〈0.05 ）. There was negative correlation between calcium content in whole plaque and dft or dfs or CSI. Conclusion ： Calcium content in whole plaque has a certain correlation with the severity of caries, and it may be used as an indicator for forecasting caries susceptibility.
