每日糖暴露、牙菌斑组成和初级牙列龋齿模式之间的关系尚不清楚。研究对象为3组儿童，共20例（1848月龄），分别为：(1)无龋（CF），(2)出现坑状和裂隙性龋（PFC），(3)出现护理性龋（NC）。评估龋齿指数（dmfs），并通过问卷调查估计每日糖暴露（TS）的频率及其形式。测定牙菌斑中氟化物(F)、钙（Ca）、无机磷（Pi）、不溶性多糖（IP）和变形链球菌。三组儿童在每日糖摄入量方面存在统计学差异。NC患儿牙菌斑中F、Ca、Pi浓度低于CF患儿，IP和变形链球菌含量高于CF患儿。PFC患儿斑块中的F和P水平也低于CF患儿。NC和PFC患儿的IP、TS和dmfs之间存在显著的统计学相关性。前牙菌斑中变形链球菌与NC儿童dmfs之间也存在统计学上的显著相关性。这些结果表明，饮食中的糖经历改变了牙菌斑的生化和微生物组成，这可以部分解释在初级牙列中观察到的不同龋齿模式。版权所有(C) 2002 S.

The relationship among daily sugar exposure, dental plaque composition and caries patterns in the primary dentition is not known. Three groups of 20 children (1848 months old) were studied: (1) caries-free (CF), (2) presenting pit and fissure caries (PFC), and (3) with nursing caries (NC). Dental caries index (dmfs) was assessed and the frequency of daily sugar exposure (TS) and its forms were estimated by questionnaires. Fluoride (F), calcium (Ca), inorganic phosphorus (Pi), insoluble polysaccharide (IP) and mutans streptococci were quantified in dental plaque. The three groups of children were statistically different regarding daily sugar exposure. Concentrations of F, Ca and Pi were lower and the IP and mutans streptococci statistically higher in dental plaque from NC children than those from CF children. PFC children also showed statistically lower F and P levels in their plaque than CF children. Statistically significant correlations were found between IP, TS and dmfs from NC and PFC children. A statistically significant correlation between mutans streptococci in plaque from anterior teeth and dmfs for NC children was also observed. These results suggest that the dietary sugar experience changes the biochemical and microbiological composition of dental plaque, which could partly explain the different caries patterns observed in primary dentition.
