含精油漱口液对成人牙菌斑和牙龈炎的抑制效果

Comparative effects of essential oil-containing mouthrinse on reduction of plaque and gingivitis

目的:探讨含精油漱口液作为机械性控制菌斑的辅助措施,对成年人减少菌斑积聚和预防牙龈炎的效果。方法:82名年龄在18～70岁的健康志愿者纳入为期6个月的随机、双盲、对照临床研究。对试验对象进行洁治和牙面抛光后,随机分为试验组和对照组,分别发给含精油的漱口液和不含精油的安慰剂漱口液。所有试验对象每天使用分发的漱口液漱口2次,每次20mL。除使用检查者统一提供的牙膏和牙刷早晚刷牙外,不进行其他口腔保健措施。分别于基线、3个月和6个月时检查受试对象的菌斑指数和牙龈指数的变化情况。采用SPSS13.0软件包对数据进行t检验。结果:3个月检查时,使用含精油成分漱口液的试验组与对照组相比,菌斑指数和龈炎指数分别降低9.02%与11.88%;6个月检查时,试验组菌斑指数和龈炎指数分别较对照组降低16.98%和21.47%,两组比较均有统计学差异(P<0.05)。结论:含精油的漱口液与安慰剂漱口液相比,具有控制牙菌斑、降低牙龈指数、改善牙龈健康的作用。

PURPOSE： The purpose of this study was to determine the efficacy of reducing plaque and gingivitis when used as an adjunct to normal oral hygiene routine and regular professional care. METHODS： Eighty-two adult subjects were enrolled into a 6-month, double-blind, controlled parallel-designed clinical study. After being scaled and polished, they were randomized into two groups： essential oil-containing mouthrinse group and placebo mouthrinse group. Everyone rinsed twice a day for 6 months with 20mL mouthrinse. The subjects were provided with a soft nylon toothbrush and fluoride toothpaste and were asked not to use any other mouthrinse during the study. At baseline and at 3- and 6-month, subjects were evaluated for supragingival plaque and gingivitis. SPSS 13.0 software package was used for statistical analysis （student＇s t test）. RESULTS： At 3- month, the essential oil-containing mouthrinse significantly produced a 9.02% inhibition of supragingival plaque development and a 11.88% inhibition of gingivitis development compared with the control group. At 6-month, the essential oil-containing mouthrinse significantly produced a 16.98% inhibition of supragingival plaque development and a 21.47% inhibition of gingivitis development compared with the control group. CONCLUSION： The essential oil-containing mouthrinse demonstrates a significant reduction in dental plaque, gingivitis and enhances overall gingival health compared with using placebo rinse.
