BACKGROUND
The present study aims to assess and compare the reduction in salivary Mutans Streptococci counts after chewing Xylitol, herbal and placebo gums among high school children.
METHODS
The study was conducted among 72 school children (12-15 years) from 3 randomly selected schools (blocks). Xylitol, herbal and placebo gums were randomly allocated to 3 blocks. Subjects were instructed to chew one pellet four times a day for 21 days. The mean reduction in salivary Streptococcus mutans count was assessed.
RESULTS
The 100% Xylitol sweetened chewing gum "Xylitol"has shown statistically significant reduction in salivary Mutans Streptococci colony forming units at the end of 21 days (P < 0.01). The reduction was not statistically significant in herbal and placebo chewing gum.
CONCLUSIONS
Hundred percentage Xylitol sweetened chewing gum was found to be more effective in reducing salivary Mutans Streptococci count when compared to herbal and placebo chewing gums.
背景
本研究旨在评估和比较高中儿童咀嚼木糖醇口香糖、草本口香糖和安慰剂口香糖后唾液中变形链球菌数量的减少情况。
方法
该研究在从3所随机选择的学校（街区）中选取的72名学童（12 - 15岁）中进行。木糖醇口香糖、草本口香糖和安慰剂口香糖被随机分配到3个组。受试者被要求每天咀嚼一粒口香糖，每天4次，持续21天。评估唾液中变形链球菌数量的平均减少情况。
结果
100%木糖醇甜味口香糖“木糖醇”在21天结束时唾液中变形链球菌菌落形成单位有统计学意义的减少（P < 0.01）。草本口香糖和安慰剂口香糖的减少没有统计学意义。
结论
与草本口香糖和安慰剂口香糖相比，发现100%木糖醇甜味口香糖在减少唾液中变形链球菌数量方面更有效。
