目标。测试评估斑块中存在的变形链球菌 (MS) 的特定位点方法的能力，以预测儿童的龋齿风险，并将结果与通过估计唾液中存在的 MS 水平获得的结果进行比较。方法。对 129 个学前班的龋齿患病率进行了两次检查，间隔 6 个月。年龄范围为 1.5 至 5 岁的儿童。使用商业条带方法评估从两个齿间空间的四个选定牙齿表面收集的牙菌斑和唾液中的 MS 评分（0-3）。结果。龋齿发生率的 MS 评分筛选标准在 1 分和 2 分之间以及 0 分和 I 分之间分别是评估牙菌斑（预测准确度为 80%）和唾液（预测准确度为 71%）的最有效标准。基于这些筛选标准，当考虑斑块MS评分时，唾液MS的评估是无效的。根据卡方检验（p < 0.01），无论基线时是否有龋齿经历，筛查牙菌斑 MS 都是有效的，但当基线时存在龋齿经历时，筛查唾液 MS 无效。包括六个变量的多变量逻辑回归分析显示，斑块MS评分和基线时的龋齿经历与龋齿发生率显着相关：基线时的龋齿经历（OR = 5.02，95％Cl：1.81-14.59）和高斑块MS评分（2或3）（OR = 12.59，95％Cl：3.18-67.08）。结论。这些结果表明，与其他重要的龋齿风险指标相比，仅从磨牙两个近端部位取样的菌斑 MS 进行半定量评估对于筛查乳牙龋齿高风险的学龄前儿童更有效。 (C) 2003 Elsevier Science Ltd.

Objectives. To test the ability of a site-specific method of evaluating mutans streptococci (MS) present in plaque in order to predict caries risk in children and to compare the results with those obtained from estimating the levels of MS present in saliva.Methods. Caries prevalence was examined twice, 6 months apart, in 129 preschool. children ranging in age from 1.5 to 5. A commercial strip method was used to evaluate the MS score (0-3) in plaque collected from four selected tooth surfaces at two interdental spaces and in saliva.Results. The screening criteria of the MS score for caries incidence between scores 1 and 2, and scores 0 and I were the most valid for evaluating plaque (accuracy of prediction, 80%) and saliva (accuracy of prediction, 71%), respectively. Based on these screening criteria, the evaluation of saliva MS was invalid when the plaque MS score was considered. Screening plaque MS was effective, regardless of caries experience at baseline, according to the chi-square test (p < 0.01), but screening saliva MS was ineffective when caries experience was present at baseline. A multivariate logistic regression analysis including six variables showed that the plaque MS score and caries experience at baseline were significantly correlated with caries incidence: caries experience at baseline (OR = 5.02, 95%Cl: 1.81-14.59) and high plaque MS score (2 or 3) (OR = 12.59, 95%Cl: 3.18-67.08).Conclusions. These results suggest that the semi-quantitative evaluation of plaque MS sampled from only two proximal sites on the molars is more effective for screening preschool children at a high risk of developing caries in their primary dentition than other important caries risk indicators.
