The aim of the study was to assess the efficacy of probiotic and green tea mouthrinse on salivary pH.
Study was conducted over a period of one month among 40 healthy school children aged between 6-8 years. The subjects who fulfilled inclusion criteria were selected and randomly divided into 2 groups namely probiotic and green tea groups. Salivary pH was recorded at baseline (0 day) and at the end of the specified time period using GC pH strips. Statistical analysis was done using paired 't' test P < 0.05 was considered statistically significant.
The comparison of mean pH scores for green tea showed that the pH of saliva was increased in the children after rinsing with green tea (6.15 to 7.65) and was statistically significant (p<0.001). Similarly when pre and post mean pH was compared in the probiotic group pH increased from (6.45 to 6.65) however, the results were not statistically significant.
The study conducted shows the beneficial effects of green tea in providing a alkaline environment which is conducive to the oral health of children.
本研究旨在评估益生菌漱口水和绿茶漱口水对唾液pH值的影响。
对40名年龄在6至8岁的健康学童进行了为期一个月的研究。选取符合纳入标准的受试者，随机分为两组，即益生菌组和绿茶组。使用GC pH试纸在基线（第0天）和指定时间段结束时记录唾液pH值。采用配对t检验进行统计分析，P < 0.05被认为具有统计学意义。
绿茶组平均pH值得分的比较表明，儿童用绿茶漱口后唾液pH值升高（从6.15升至7.65），且具有统计学意义（p<0.001）。同样，益生菌组比较前后平均pH值时，pH值从（6.45升至6.65），然而，结果无统计学意义。
本研究表明绿茶在提供有利于儿童口腔健康的碱性环境方面具有有益作用。
