The study compared and evaluated the effects of tongue scraping and tongue brushing on salivary mutans streptococci levels in children.
The investigation was a single-blind, stratified comparison of three parallel groups of children who performed either tongue scraping or tongue brushing along with tooth brushing or only tooth brushing twice daily under professional supervision for a 21-day period. A total of three saliva samples were taken from each individual, at baseline, on day 10 and on day 21, and colony counts of mutans streptococci were determined. All data were subjected to statistical analysis using Wilcoxon's signed-ranks sum test and Mann-Whitney U-test.
The results of the present study show that tongue scraping and tongue brushing demonstrated statistically significant reductions in salivary mutans streptococci counts after 10 days and also after 21 days. It was also noted that tongue scraping and tongue brushing were equally effective in reducing colony counts.
本研究比较和评估了刮舌和刷舌对儿童唾液变形链球菌水平的影响。
这是一项单盲、分层比较研究，将三组接受专业监督的儿童分为三组，分别进行刮舌、刷舌以及每天两次刷牙，共 21 天。在基线、第 10 天和第 21 天，从每个个体中采集 3 份唾液样本，并测定变形链球菌的菌落计数。所有数据均采用 Wilcoxon 符号秩和检验和 Mann-Whitney U 检验进行统计分析。
本研究结果表明，刮舌和刷舌在第 10 天和第 21 天后均可显著降低唾液变形链球菌计数。还注意到，刮舌和刷舌在降低菌落计数方面同样有效。
