目的:观察盐酸米诺环素软膏联合甲硝唑药膜治疗牙周炎的疗效及其对患者龈沟液中C反应蛋白（CRP）、弹性蛋白酶水平的影响。方法:选取嘉兴市中医医院2019年5月至2020年1月治疗的牙周炎患者76例，采用随机数字表法分为观察组、对照组各38例。两组均予甲硝唑药膜治疗，观察组在此基础上联合盐酸米诺环素软膏治疗，两组疗程4周。比较两组临床疗效，治疗前后牙周系统检查指标［牙龈指数（GI）、牙周探诊深度（PD）、牙龈出血指数（BI）、菌斑指数（PLI）、附着丧失（AL）］、龈沟液生化指标［CRP、细胞内弹性蛋白酶（EA-p）、细胞外弹性蛋白酶（EA-s）］水平，不良反应发生情况及随访半年复发率。结果:观察组总有效率为97.37%（37/38），高于对照组的78.95%（30/38）（χn 2=6.17，n P < 0.05）。治疗后，观察组GI、PD、BI、PLI、AL均低于对照组（均 n P < 0.001）；观察组龈沟液CRP、EA-p、EA-s分别为（5.31±1.19）μg/L、（0.70±0.20）Abs/mL、（0.48±0.19）Abs/mL，均低于对照组的（7.92±1.27）μg/L、（1.15±0.52）Abs/mL、（1.12±0.31）Abs/mL（ n t=9.24、4.97、10.85，均n P < 0.001）。观察组半年内复发率为2.63%（1/38），低于对照组的20%（6/38）（χ n 2=3.93，n P 0.05）。n 结论:盐酸米诺环素软膏联合甲硝唑药膜治疗牙周炎安全有效，有助于下调龈沟液CRP、EA-p、EA-s水平，缓解炎症，改善牙周状况，减少复发。“,”Objective:To investigate the efficacy of minocycline hydrochloride ointment combined with metronidazole film in the treatment of periodontitis and their effects on C-reactive protein and elastase levels in the gingival crevicular fluid.Methods:76 patients with periodontitis who received treatment in Jiaxing Hospital of Traditional Chinese Medicine from May 2019 to January 2020 were included in this study. They were randomly allocated to undergo treatment with metronidazole film (control group, n n = 38) or minocycline hydrochloride ointment plus metronidazole film (observation group, n n = 38) for 4 weeks. We compared clinical efficacy, periodontal system examination indexes (gingival index, periodontal probing pocket depth, gingival bleeding index, plaque index, loss of attachment), gingival crevicular fluid biochemical markers (C-reactive protein, elastase in the pellet, elastase in the supernatant) measured before and after treatment, the incidence of adverse reactions, and the recurrence rate within half a year after treatment between the two groups.n Results:The total response rate was significantly higher in the observation group than in the control group [97.37% (37/38) n vs. 78.95% (30/38), n χ2 = 6.17n , P < 0.05]. Gingival index, periodontal probing pocket depth, gingival bleeding index, plaque index, and loss of attachment measured after treatment were significantly lower in the observation group than in the control group (all n P < 0.001). C-reactive protein, elastase in the pellet, and elastase in the supernatant measured after treatment were (5.31 ± 1.19) μg/L, (0.70 ± 0.20) Abs/mL, (0.48 ± 0.19) Abs/mL respectively in the observation group, which were significantly lower than those in the control group [(7.92 ± 1.27) μg/L, (1.15 ± 0.52) Abs/mL, (1.12 ± 0.31) Abs/mL, n t = 9.24, 4.97, 10.85, all n P < 0.001]. The recurrence rate within half a year in the observation group was significantly lower than that in the control group [2.63% (1/38) n vs. 20% (6/38), n χ2 = 3.93, n P 0.05).n Conclusion:Minocycline hydrochloride ointment combined with metronidazole film is safe and effective in the treatment of periodontitis. The combined therapy help downregulate the levels of C-reactive protein, elastase in the pellet, elastase in the supernatant of the gingival crevicular fluid, alleviate inflammation, improve the periodontal status, and reduce the recurrence rate.
