To assess possible relationship between caries experience, salivary cariogenic microflora and free sugar consumption in 6 year and 12 year old children in Riga, to evaluate these variables in risk assessment.
79 children aged 6 and 96 children aged 12 were examined clinically and by bitewing X-ray for caries diagnosis. Also all children or their parents were questioned about number of tea spoons containing sugar used per cup and frequency of cups used daily. Salivary mutans streptococci (MS) and lactobacilli (LB) (CRT-bacteria; Ivoclar; Vivadent; Liechtenstein) were determined only for children with dmft/DMFT>4: 27.8% at the age of 6, 40.6% at the age of 12. All data were statistically analyzed using frequency tables and analysis of variance. Statistical significance of differences in proportions was tested using chi-square test, Analysis included evaluation of how changes in variables such as free sugar consumption affects caries in particular age group.
Mean number of tea spoons containing sugar used per cup was 1.47 in 6 year olds and 1.86 in 12 year olds, but daily amount of tea spoons containing sugar was 2.71 and 4.36 in each age group accordingly. Tea spoons of sugar per cup were associated with caries experience only in 6 year olds (p=0.098). A significant association was observed between caries experience, salivary MS and an amount of tea spoons containing sugar used per cup in both age groups (for 6 y.o. p= 0.037, for 12 y.o. p=0.037). Also caries experience was strongly associated with salivary MS and daily amount of tea spoons containing sugar, but only in 12 year olds (p=0.041).
The information of free sugar consumption per cup or daily gives the possibility to control free sugar use in order to reduce caries development in 6 year old and 12 year old children in Riga.
评估里加6岁和12岁儿童的龋齿经历、唾液致龋微生物群与游离糖摄入量之间的可能关系，在风险评估中评估这些变量。
对79名6岁儿童和96名12岁儿童进行临床检查，并通过咬合翼片X线进行龋齿诊断。此外，还询问了所有儿童或其父母每杯含糖茶匙数以及每日杯数。仅对dmft/DMFT>4的儿童测定唾液变形链球菌（MS）和乳酸菌（LB）（CRT细菌；义获嘉；唯瓦登特；列支敦士登）：6岁儿童中占27.8%，12岁儿童中占40.6%。所有数据使用频率表和方差分析进行统计分析。使用卡方检验检验比例差异的统计学显著性，分析包括评估游离糖摄入量等变量的变化如何影响特定年龄组的龋齿情况。
6岁儿童每杯含糖茶匙平均数为1.47，12岁儿童为1.86，但各年龄组每日含糖茶匙数分别为2.71和4.36。每杯含糖茶匙数仅在6岁儿童中与龋齿经历相关（p=0.098）。在两个年龄组中，龋齿经历、唾液MS与每杯含糖茶匙数之间均观察到显著关联（6岁儿童p=0.037，12岁儿童p=0.037）。此外龋齿经历与唾液MS和每日含糖茶匙数密切相关，但仅在12岁儿童中如此（p=0.041）。
每杯或每日游离糖摄入量信息为控制游离糖使用提供了可能性，以减少里加6岁和12岁儿童的龋齿发生。
