低摩擦抗敏牙膏与非抗敏牙膏菌斑清除效率的对比研究

A comparative study of plaque removal efficiency with low friction desensitizing toothpaste and desensitizing toothpaste

目的评价低摩擦抗敏牙膏与非抗敏牙膏在控制菌斑方面的效果。方法本试验采用双盲、随机对照方法,选取符合纳入标准的50名受试者,每位受试者随机选取左右一侧使用1号牙膏,另一侧使用2号牙膏,后期揭盲1号牙膏为含8%精氨酸的低摩擦抗敏牙膏,2号牙膏为非抗敏牙膏。记录左右侧分别刷牙15 s、30 s、60 s、120 s时的左右半口牙菌斑指数,统计分析使用2种牙膏后的菌斑指数,评价低摩擦抗敏牙膏在控制菌斑方面的效果。结果在单侧刷牙60 s内非抗敏牙膏菌斑清除效率高于低摩擦抗敏牙膏,但在120 s后两者菌斑清除效率无统计学差异。结论使用低摩擦抗敏牙膏刷牙超过120 s,可以达到与非抗敏牙膏相同的菌斑清除效果。

Objective To evaluate the plaque control effect of desensitizing toothpaste with low friction and normal toothpaste,Meth- otis A randomized, controlled, double-blind clinical trial was used. A total of 50 volunteers were recruited into the study. Everyone chose one side of mouth to use NO. 1 toothpaste, and the other side used NO.2 toothpaste, then the toothpastes were unblinded, the NO. 1 toothpaste was low friction desensitizing toothpaste containing 8% of arginine. The PLI of both sides was recorded respectively be- fore brushing, after 15 seconds＇ brushing, 30 seconds＇ brushing, 60 seconds＇ brushing and 120 seconds＇ brushing. The effect of de- sensitizing toothpaste with low friction in plaque control was evaluated after statistical analysis. Results The plaque removal efficiency of normal toothpaste was higher than desensitizing toothpaste with low friction in 60 seconds, but there was no statistical difference be- tween the two kinds of toothpaste after 120 seconds. Conclusion Desensitizing toothpaste with low friction can achieve the same effect of plaque removal as normal toothpaste after 120 seconds＇ brushing.
