不同根面处理剂对牙周围翻瓣术后的疗效分析

Different Periodontal Root Surface Treatment Agent on the Efficacy of Postoperative Flap

目的探讨牙周翻瓣术后用盐酸多西环素和EDTA为根面处理剂的临床效果。方法将25例慢性牙周炎患者进行四周时间基础治疗后,以其75个翻瓣术区作为研究对象,每例患者选择口腔内病情相似的3个术区,随机分为EDTA处理组、盐酸多西环素处理组(DH组)、仅进行牙周翻瓣术的空白对照组(OFD组)。术前记录龈沟出血指数(SBI)、牙周袋探诊深度(PPD)、附着丧失(CAL)。手术中进行根面平整后,实验组根面涂EDTA和盐酸多西环素,5min后,生理盐水清洗,缝合。空白对照组只用生理盐水清洗缝合。术后3个月,复查患者SBI、PPD、CAL。结果术后3个月,3组的SBI、PPD、CAL都显著减少(P<0.05),EDTA处理组与盐酸多西环素处理组相比空白对照组3项指标也明显变小(P<0.05)。结论两种根面处理剂在牙周围翻瓣术后,以盐酸多西环素恢复效果更好。

Objective To investigate the periodontal flap surgery doxycycline hydrochloride and EDTA root surface treatment agent for the clinical effect.Methods 25 patients with chronic periodontitis were based on four weeks after treatment,with its 75 district as flap surgery study,each patient selected oral surgery disease similar to the 3 areas,were randomly divided into treatment group,EDTA doxycycline hydrochloride treatment group（DH group）,only for periodontal flap surgery control group（OFD group）.Recorded before surgery and sulcus bleeding index（SBI）,probing pocket depth（PPD）,attachment loss（CAL）.Surgery,root planing,the experimental group topcoat EDTA and doxycycline hydrochloride,5 minutes later,saline wash,stitching.Control group only normal saline wash suture.After 3 months,review the patient SBI,PPD,CAL.Results After three months,three groups of SBI,PPD,CAL were significantly reduced（P0.05）,EDTA treatment group and doxycycline hydrochloride treatment group compared to the three indicators of the control group was significantly smaller（P0.05）.Conclusion The tooth root surface treatment agent after flap around in order to restore doxycycline hydrochloride better.
