The aim of this study was to evaluate and compare the effect of tongue scraping, tongue brushing, and saturated saline on salivary MS levels.
A single-blinded, randomized, parallel group clinical trial was conducted in children aged 9-12 years. Total sample of 45 subjects were randomly assigned to three groups, that is, Group A, Group B, and Group C comprised of 15 each. Group A, Group B, and Group C were asked to do tongue scraping, tongue brushing and saturated saline rinsing twice daily, respectively for 21 days. Saliva samples, collected from the subjects on the baseline, 7(th) day and 21(st) day, were inoculated on mitis salivarius bacitracin agar and incubated at 37°C for 48 h. The mean streptococcal colony forming counts were enumerated. The data were subjected to statistical analysis using Wilcoxon signed rank sum test for intragroup comparisons and Mann-Whitney U-test for intergroup comparisons.
Intragroup comparisons showed statistically significant reduction in MS levels (P < 0.01). However, the intergroup comparisons showed no statistically significant difference (P > 0.05).
The oral hygiene measures evaluated proved equal efficacy in reducing the colony counts. Hence, there is a need to emphasize the importance of incorporating supplementary oral hygiene measures in daily oral care.
本研究旨在评估和比较舌刮、舌刷及饱和盐水对唾液变形链球菌（MS）水平的影响。
对9至12岁儿童进行了一项单盲、随机、平行组临床试验。45名受试者的总样本被随机分为三组，即A组、B组和C组，每组各15人。分别要求A组、B组和C组受试者每天进行两次舌刮、舌刷和饱和盐水漱口，共21天。在基线、第7天和第21天从受试者收集唾液样本，接种于唾液链球菌杆菌肽琼脂上，并在37°C下孵育48小时。计算链球菌集落形成的平均计数。数据采用Wilcoxon符号秩和检验进行组内比较，采用Mann-Whitney U检验进行组间比较。
组内比较显示MS水平有统计学显著降低（P < 0.01）。然而，组间比较显示无统计学显著差异（P > 0.05）。
所评估的口腔卫生措施在减少菌落计数方面显示出同等疗效。因此，有必要强调在日常口腔护理中纳入补充口腔卫生措施的重要性。
