Recent studies have suggested that the identification of caries as discrete patterns may be valuable in describing and predicting caries experience on an individual basis. The purpose of this study was to assess the association between levels of salivary mutans streptococci and the prevalence, incidence and distribution of caries patterns in the primary dentition. A cohort of pre-school children (n = 146, mean age 3.8 yr) were examined for dental caries and sampled for salivary mutans streptococci (SMS) at baseline and once annually for 2 yr. Children's tooth surfaces were categorized into four patterns: pit/fissure, maxillary anterior, posterior proximal, and buccal/lingual smooth surface. Salivary mutans streptococci were enumerated using a tongue blade technique, and were categorized as low (0 CFU), moderate (1-50 CFU) and high (> 50 CFU). At year 2, children with high baseline SMS had the 1) highest prevalence of caries (87%) and the highest dmfs (9.15); 2) highest prevalence of each pattern, and 3) greatest number of patterns. Among children with the pit/fissure pattern, those with high baseline SMS had the greatest pit/fissure dmfs after 2 yr. Results show that baseline SMS levels were associated with both cross-sectional and longitudinal caries experience, numbers of caries patterns, and the prevalence and severity of those patterns.
最近的研究表明，将龋齿识别为离散模式对于个体层面描述和预测龋齿经历可能具有重要价值。本研究的目的是评估唾液变形链球菌水平与乳牙列中龋齿模式的患病率、发病率和分布之间的关联。对一组学龄前儿童（n = 146，平均年龄3.8岁）进行了龋齿检查，并在基线时以及之后的2年中每年采集一次唾液样本以检测变形链球菌（SMS）。儿童的牙齿表面被分为四种模式：窝沟、上颌前牙、后牙邻面和颊/舌光滑面。使用舌板技术对唾液变形链球菌进行计数，并分为低（0 CFU）、中（1 - 50 CFU）和高（> 50 CFU）三类。在第2年时，基线SMS水平高的儿童有：1）最高的龋齿患病率（87%）和最高的dmfs（9.15）；2）每种模式的最高患病率；3）最多的模式数量。在患有窝沟模式龋齿的儿童中，基线SMS水平高的儿童在2年后窝沟dmfs最高。结果表明，基线SMS水平与横断面和纵向龋齿经历、龋齿模式数量以及这些模式的患病率和严重程度均相关。
