目的探讨EDTA联合翻版术治疗牙周炎的临床疗效。方法本院24例慢性牙周炎患者给予4周基础治疗后,左侧归为实验组,右侧归为对照组作为自身对照。将中切牙至第一磨牙作为翻瓣区,并刮尽牙石、肉芽。实验组术后给予EDTA涂擦根面,然后采用生理盐水冲洗;对照组仅给予生理盐水冲洗。分别于术前、术后比较两组患者的龈沟出血指数(SBI)、牙周袋探诊深度(PD)、附着丧失(CAL)。结果两组术后SBI、PD、CAL较术前均显著下降(P<0.05),但实验组指标改善显著优于对照组(P<0.05)。结论采用EDTA处理根面能够显著提高翻瓣术治疗牙周炎的临床疗效,值得临床推广应用。
Objective To investigate the clinical efficacy of EDTA combined with replica in the treatment of periodontitis. Methods 24 patients with chronic periodontitis were given 4 weeks of basic treatment, the left is classified as experimental group, the right is classified as control group as their own control. The incisors to the first molars flap area, and scrape tartar, granulation. The experimental group was treated with EDTA to rub the root surface, and then washed with saline; the control group only given saline wash. The sulcus bleeding index (SBI), probing depth (PD) and attachment loss (CAL) of the two groups were compared before and after surgery respectively. Results The SBI, PD and CAL of the two groups were significantly lower than those before the operation (P <0.05), but the improvement of the experimental group was significantly better than that of the control group (P <0.05). Conclusion EDTA treatment of root surface can significantly improve the flap flap surgery for the treatment of periodontitis clinical efficacy, worthy of clinical application.
