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。
Objective: To explore the effect of using essential oil mouthwash as a mechanical control plaque to reduce plaque accumulation and prevent gingivitis in adults. Methods: Eighty healthy volunteers aged 18-70 years were enrolled in a randomized, double-blind, controlled clinical trial of 6 months. The subjects were cleansed and tooth surface polished, were randomly divided into experimental group and control group, were sent to the oil-containing mouthwash and oil-free placebo mouthwash. All subjects were given gargle 2 times a day, 20 mL each time. In addition to using the uniform toothbrush and toothbrush provided by the examiner, no other oral hygiene measures are taken. The changes of plaque index and gingival index of the subjects were examined at baseline, 3 months and 6 months respectively. SPSS13.0 software package for t test data. Results: Compared with the control group, the plaque index and gingivitis index decreased by 9.02% and 11.88%, respectively, in the test group using the mouthwash containing essential oil component at 3 months. At the 6th month, the plaque index And gingivitis index decreased by 16.98% and 21.47% respectively compared with the control group. There was significant difference between the two groups (P <0.05). Conclusions: Compared with placebo, the mouthwash containing essential oils has the effect of controlling plaque, reducing the gingival index and improving the health of gums.
