采用双盲随机对照法,观察一种新型的氯化十六烷基吡啶(Cetylpyridinium chloride,CPC)含漱剂对已形成的牙菌斑及慢性牙龈炎的疗效。实验过程中,120例慢性牙龈炎患者维持原有的口腔卫生习惯。结果显示,实验组的菌斑指数、牙龈指数及龈沟出血指数值在治疗后第7天与第14天时,均较服安慰剂组为低(P<0.01)。实验表明:CPC含漱剂能有效地控制菌斑,减轻龈炎的程度,改善患者的出血症状,且副作用极小。因而认为该种新型的漱口液在临床应用方面具有良好的前景。
A double-blind randomized controlled trial was conducted to evaluate the efficacy of a new Cetylpyridinium chloride (CPC) gargle on plaque and chronic gingivitis. During the experiment, 120 patients with chronic gingivitis maintained their original oral health habits. The results showed that the plaque index, gingival index and sulcus bleeding index in the experimental group were lower than those in the placebo group on the 7th and the 14th day after treatment (P <0.01). Experiments show that: CPC gargle can effectively control plaque, reduce the degree of gingivitis, improve the patient's bleeding symptoms, and minimal side effects. So that the new type of mouthwash has a good prospect in clinical application.
