牙周基础治疗对口腔扁平苔藓伴慢性牙周炎患者外周血MMP-3及IFN-γ水平的影响

摘要

Objective:To investigate the significance of periodontal treatment on the levels of MMP-3 and IFN-γin the serum of patients with oral lichen planus(OLP) and chronic periodontitis(CP) before and after treatment.Methods:60 patients with erosion OLP and CP were divided into 2 groups randomly (n =30).The patients in experimental group received basic periodontal treatment combined with drug therapy,those in control group received drug therapy only.Before and after treatment the periodontal indexes of PD,AL,BI and PLI were measured in the experimental group,the levels of MMP-3 and IFN-γ in serum were tested by ELISA in the 2 groups,the differences of the data between 2 groups were statistically analysed.Results:After treatment the periodontol indexes were decreased in the experimental group(P ＜ 0.05),the serum MMP-3 and IFN-γ levels were lower than those before treatment in 2 groups(P＜0.05),and the decline of MMP-3 and IFN-γ in experimental group was more obvious than those in the control group (P＜0.05).Conclusion:Periodontal initial therapy has positive influence on the treatment of OLP and can reduce the level of inflammation.%目的:观察牙周基础治疗前后口腔扁平苔藓伴慢性牙周炎患者血清中基质金属蛋白酶-3(MMP-3)和干扰素-γ(IFN-γ)浓度的变化.方法:选取60例诊断为伴有牙周炎的糜烂型口腔扁平苔藓患者,随机分为2组,其中实验组30例进行牙周基础治疗联合药物治疗,治疗前后,检测牙周指数PD、AL、BI和PLI.对照组30例采取药物治疗.用ELLSA检测治疗前后2组患者血清中MMP-3及IFN-γ的表达水平,分析各组细胞因子浓度的差异.结果:治疗后实验组牙周指数明显下降(P＜0.05);2组患者血清中的MMP-3及IFN-γ表达水平与治疗前相比下降(P＜0.05);经过治疗后,实验组MMP-3及IFN-γ表达水平下降趋势较对照组明显(P＜0.05).结论:牙周基础治疗在口腔扁平苔藓治疗中起到了积极作用,可有效降低炎症水平.
