麦芽糖醇口香糖对青少年牙菌斑的抑制效果

目的评价麦芽糖醇口香糖控制青少年牙菌斑集聚水平的临床效果。方法将30名13～15岁龋易感受试者随机分为A、B、C组,根据分组分别每天咀嚼麦芽糖醇口香糖、木糖醇口香糖、胶母基口香糖5次,每次10 min。采用改良Quigley-Hein菌斑指数记录法分别于基线、4周时检查受试者的菌斑指数情况。应用SPSS 17.0软件对数据进行统计分析。结果咀嚼口香糖4周后,3组受试者的菌斑指数都有明显下降,与基线相比的差异有统计学意义（P=0.000、0.000、0.006）;3组菌斑指数变化间的差异也有统计学意义（P=0.015）,组间两两比较结果表明,A组与B组菌斑指数变化间的差异无统计学意义（P=0.687）,而A组与C组、B组与C组菌斑指数变化间的差异有统计学意义（P=0.019、0.007）。结论麦芽糖醇口香糖对青少年牙菌斑的抑制效果与木糖醇口香糖相似。

Comparative effects of the maltitol chewing gums on reducing plaque

Objective To estimate the clinical effect of the maltitol chewing gums in plaque control. Methods Thirty 13-15 years old susceptible adolescent were divided into three groups randomly, group A（maltitol chewing gums）, group B（xylitol chewing gums） and group C（gum base chewing gums）. Subjects chewed gums 5 times each day, 10 min each time. At baseline and at 4-week, subjects were evaluated for supragingival plaque. SPSS 17.0 software package was used for statistical analysis. Results Four weeks later, plaque index of the three groups continulously step down. Significant difference was observed between baseline and 4-week（P=0.000, 0.000, 0.006）. Four weeks later, there was statistically significant difference in clearance rate of plaque among the three groups（P =0.015）. There was still no statistically significant difference between group A and group B（P=0.687）, but they were both different from C group（P=0.019, 0.007）. Conclusion Maltitol chewing gum can lead to similar effect on reduction of plaque as xylitol chewing gum.
