目的:观察复方奥硝唑大黄缓释膜联合超声洁治术治疗慢性牙周炎的临床疗效。方法:将80例慢性牙周炎患者随机分为治疗组和对照组,治疗组40例(115颗牙)采用超声洁治术联合复方奥硝唑大黄缓释膜治疗;对照组40例(127颗牙)采用超声洁治术治疗。比较两组患者牙龈指数(GI)、龈沟出血指数(BI)、探诊深度(PD)、检测龈沟液(GCF)及治疗有效率。结果:两组治疗后GI、BI、PD、GCF均有改善(P<0.05),但治疗组疗效优于对照组(P<0.05);治疗组总有效率为94.8%,对照组总有效率为66.1%,治疗组优于对照组(P<0.05)。结论:复方奥硝唑大黄缓释膜联合超声洁治术治疗慢性牙周炎疗效显著。
Objective: To observe the clinical efficacy of compound ornidazole rhubarb sustained-release membrane combined with ultrasonic cleaning in the treatment of chronic periodontitis. Methods: Eighty patients with chronic periodontitis were randomly divided into treatment group and control group. 40 cases (115 teeth) in the treatment group were treated by ultrasonic cleaning combined with ornidazole rhubarb sustained-release membrane. In the control group, 40 cases (127 Tooth) using ultrasonic cleaning treatment. Gingival index (GI), sulcus bleeding index (BI), probing depth (PD), GCF and therapeutic efficiency were compared between the two groups. Results: The GI, BI, PD and GCF of both groups were improved after treatment (P <0.05), but the treatment group was better than the control group (P <0.05). The total effective rate was 94.8% in the treatment group. The total effective rate 66.1%, the treatment group was better than the control group (P <0.05). Conclusion: Compound ornidazole rhubarb sustained release membrane combined with ultrasonic cleaning treatment of chronic periodontitis significant effect.
