Regular consumption of sweetened beverages has been associated with dental caries, which is mediated through salivary pH. The salivary pH changes among individuals with low caries experience after consumption of two local sweetened drinks is compared.
In this block randomised controlled parallel group, an open-label pilot study of 49 participants aged 21-25 were selected. The participants were randomised into three groups: mineral water, chocolate drink and . One day prior to the test, scaling was done and the participants did not eat or drink anything on the test day till the saliva sample collection was done. Salivary pH was measured at baseline and after the consumption of the drinks with a glass electrode digital pH meter at five-minute interval for half an hour. The statistical significance was assessed at the level of 5%.
After consumption of chocolate drink and , the salivary pH dropped from a baseline of 7.09 for chocolate drink and 7.13 for to 6.69 for chocolate and 6.86 for . This difference was statistically significant ( < 0.001).
Sweetened milk based local drinks can increase the caries susceptibility. In the community, information about limiting the intake of sweetened drinks should be reinforced.
经常饮用含糖饮料与龋齿有关，这是通过唾液pH值介导的。比较了饮用两种当地含糖饮料后龋齿经历较少的个体之间的唾液pH值变化。
在这项整群随机对照平行组开放标签的试点研究中，选取了49名年龄在21至25岁之间的参与者。参与者被随机分为三组：矿泉水组、巧克力饮料组和……。在测试前一天进行洗牙，参与者在测试当天直到采集唾液样本前不吃不喝。在基线时以及饮用饮料后，使用玻璃电极数字pH计每隔五分钟测量一次唾液pH值，持续半小时。在5%的水平评估统计学显著性。
饮用巧克力饮料和……后，巧克力饮料组的唾液pH值从基线的7.09降至6.69，……组从7.13降至6.86。这种差异具有统计学显著性（<0.001）。
以甜牛奶为基础的当地饮料会增加龋齿易感性。在社区中，应加强关于限制含糖饮料摄入量的宣传。
