摘要
目的 :了解聚维酮碘 (PVP -I)和生理盐水配合基础治疗后龈沟液中GPx的变化和临床意义。方法 :2 3名慢性成年性牙周炎 (AP)患者 ,每一测试者选取不同象限的 1～ 2个患牙 ,总共 44颗 2 2对牙在基础治疗完成后 ,一组用 10 % (PVP -I) ,另一组用生理盐水冲洗 ,记录临床指标GI、PD、AL ,并测定治疗前后龈沟液中GPx水平。结果 :两组治疗前后临床指标均明显下降 (p <0 0 0 1) ;GPx水平明显上升 (p <0 0 0 1) ;PVP - Ⅰ组和生理盐水组 ,各临床指标和GPx水平无显著差异。结论 :AP患者基础治疗后临床指标和生化指标GPx有明显改善 ,但配合使用PVP - Ⅰ和生理盐水冲洗对GCF -GPx水平无明显改善 ,GCF
Objective:To evaluate GPx activity in gingival crevicular after AP patient by use of non-surgical treatment and povodine-iodine.Methods:GCF was collected fron 23 AP Patients,44 Periodontitis sites.GCF-GPx activity was determined by DTNB methods before and after treatment,the periodontal parameters G .PD and AL were recorded.Results:After treatment,clinical indices decreased while GPx activity increased,but the increment of GPX activity showed neither correlation with base level nor the decrement of the clinical indices.There was no significantly difference by use of povoddine-iodine or physiological saline.Conclusion:GCF-GPx might be a promising indicator of periodontal status.
