This study aimed to investigate the salivary characteristics and individual daily living patterns in Korean children aged 12 years and evaluate their relationships according to the significant caries (SiC) index. The study sample consisted of 52 healthy Korean children. The subjects were allocated into a low caries-affected (low CA) group and a high caries-affected (high CA) group, according to the SiC index. Children underwent a standardized oral examination, and parents completed the questionnaires. Stimulated salivary samples were collected to evaluate the salivary pH, salivary flow rate, and salivary levels of (MS) and (LB). The low CA group did not significantly differ from the high CA group for salivary flow rate and salivary pH. However, there were significant differences in salivary MS levels between the two groups ( < 0.05). Among the individual casual parameters, the prevalence of a sugar-associated primary energy source between meals was significantly higher in the high CA group than in the low CA group ( < 0.05). Within the limitations of this study, different levels of salivary MS and the consumption of different foods were observed in the low CA and high CA groups. The implications of these findings should be considered for caries susceptibility.
本研究旨在调查韩国 12 岁儿童的唾液特征和个体日常活动模式，并根据龋失补指数（dmft）评估其相关性。研究样本包括 52 名健康的韩国儿童。根据 dmft 指数，将受试者分为低龋组（low CA）和高龋组（high CA）。对儿童进行标准化口腔检查，家长填写问卷。收集刺激唾液样本以评估唾液 pH 值、唾液流速和 （MS） 和 （LB） 的唾液水平。低龋组与高龋组在唾液流速和 pH 值方面无显著差异。然而，两组间唾液 MS 水平存在显著差异（<0.05）。在个体偶然参数中，高龋组中两餐间摄入含糖主要能量源的发生率显著高于低龋组（<0.05）。在本研究的限制范围内，低龋组和高龋组的唾液 MS 水平和不同食物的摄入存在差异。这些发现的意义应考虑到龋病易感性。
