奥硝唑联合洁刮术与单纯洁刮术治疗慢性牙周炎疗效对比观察

目的对比评价奥硝唑牙周条联合洁刮术、单纯洁刮术治疗慢性牙周炎的临床疗效。方法：选择我院门诊慢性牙周炎患者58例（336牙），将受试牙随机单盲分为治疗组168牙，对照组168牙。治疗组、对照组均进行龈上洁刮，用沽治器去除龈上菌斑和牙石，1周后复查。在基线（O d）时，对照组168牙行单纯龈下洁刮术，用比较精细的龈下刮治器刮除位于牙周袋内根面上的牙石和菌斑以及牙根表面感染的病变牙骨质。检测2组患牙治疗前后各项临床指标的变化。结果：数据显示，研究组基线（45 d）的GI、BI、PD、GCF等指标均明显优于基线（0 d）与对照组基线（45 d），差异具有统计学意义（P〈0．05），研究组总有效率为95．2％，对照组为77．4％，2组存在明显统计学差异（P〈0．05）。在治疗后研究组的牙龈指数和牙龈出血指数显著低于对照组，2组存在统计学差异（P〈0．05）。结论：表明奥硝唑牙周条联合洁刮术治疗慢性牙周炎显著高于单纯洁刮术，值得临床推广应用。

Objective To compare and evaluate the clinical efficacy of the treatment of chronic periodontitis with the combination of theperiodontal tissue of the. Methods： 58 patients （336teeth） with chronic periodontitis were randomly divided into the treatment group （168 teeth）and the control group （168 teeth）, which were randomly divided into the treatment group and the control group. The treatment group and thecontrol group were supragingival scaling, removal of supragingival plaque and calculus with scaler for 6 weeks. In the baseline （0d）, controlgroup 84 Yahang simple subgingival sealers operation, with fine subgingival scaler scraping in the periodontal pocket IRS calculus and plaqueand the surface of infected root diseased cementum. To detect the changes of the two groups before and after treatment the clinical indicators ofteeth. Results： Data display, on the baseline （45 d） GI, Bi, PD, GCF, indexes were significantly better than the baseline （0 d） and control groupsat baseline （45 d）, the difference is statistically significant （P〈0．05）, the study group was markedly effective for 106 cases, invalid 8 cases. Thetotal effective rate was 95.2%, 62 cases in the control group were markedly, invalid for 38 cases. The total effective rate was 77.4%, betweenthe two groups exist significant difference （P〈0．05）.The gingival index and bleeding index in the study group were significantly lower than thosein the control group, and there were significant differences between the two groups （P〈0.05）. Conclusion：Ornidazole combined periodontalscaling and surgery in the treatment of chronic periodontitis was significantly higher than that of single pure curettage.
