目的：观察替硝唑联合龈下刮治、根面平整治疗重度慢性牙周炎的临床疗效。方法：重度慢性牙周炎患者100例，依据患者的治疗方式的不同分为观察组50例，采用替硝唑联合龈下刮治术、根面平整术治疗；对照组50例采用根面平整术治疗。记录并比较两组术后1、3个月牙周探诊深度（PD）、临床附着水平（釉牙骨质界至袋底的距离，CAL）和探诊出血情况。结果：两组治疗后1、3个月PD与CAL均低于治疗前，且观察组治疗后低于对照组（P均＜0.05）。观察组治疗后1、3个月探诊出血率分别为42.0%、24.7%，对照组分别为52.7%、42.0%，两组治疗后均低于治疗前，且观察组低于对照组（P均＜0.05）。结论：替硝唑联合龈下刮治、根面平整治疗重度慢性牙周炎疗效较好，优于仅行根面平整术。

Objective: To investigate the curative effect of tinidazole combined with subgingival scaling and root planning on chronic severe periodontitis.Methods:100 cases of patients with chronic severe periodontitis were divided into observation group and control group, 50 cases in each group. Patients in observation group received tinidazole combined with subgingival scaling and root planning therapy, while patients in control group were treated with root planning. The probing depth (PD), clinical attachment level (CAL) and bleeding amount postoperatively 1 and 3 months were recorded.Results:The PD and CAL of two groups all significantly decreased after operation, and that of observation were also significantly lower than that of control group (P<0.05). The bleeding rate postoperatively 1 and 3 months of observation group were 42.0%, 24.7% respectively, and control group were 52.7%, 42.0%, respectively. The bleeding rate of of two groups all significantly decreased after operation, with significant difference between two groups (P<0.05). Conclusion:Treatment with tinidazole combined with subgingival scaling and root planning on chronic severe periodontitis showed good effect and was better than simple root planning.
