牙周牙髓联合治疗在重度牙周炎病例中的疗效

目的探讨牙周牙髓联合治疗对重度牙周炎的临床疗效。方法将80例重度牙周炎患者随机分为两组（各40例）对照组和观察组,对照组采用单纯牙周治疗措施,观察组采用牙周牙髓联合治疗措施,观察两组患者治疗前、治疗第4周、治疗第8周牙周袋探诊深度（PD）、菌斑指数（PLI）、龈沟出血指数（SBI）、松动度（MD）的水平变化情况。结果 （1）两组治疗后PD、PLI、SBI、MD均较治疗前改善,与对照组比较,观察组改善的程度较为明显（P〈0.05）;（2）随着治疗时间的延长,观察组的PD、PLI、SBI、MD指数逐渐改善,第8周疗效优于第4周（P〈0.05）;对照组第8周疗效与第4周比较无统计学差异（P〉0.05）。结论牙周牙髓联合治疗对重度牙周炎有理想临床疗效,通过促进牙周组织的再生达到治疗目的,临床建议推广运用。

The efficacy of periodontic-endodonic treatment in treating severe periodontitis

Objective To investigate the efficacy of periodontic - endodonic treatment in treating severe periodontitis. Methods 80 patients with severe periodontitis were randomly divided into 2 groups （ control group and observation group, 40 cases in each group）, patients in control group adopted simple periodontal treatment, an patients in observation group received periodontic - endodonie treatment, we observed the periodontal pocket probing depth （PD）, plaque index （PLI）, gingival sulcus bleeding index （SBI）, loose degree （MD） level changes in two groups after 4 and 8 weeks treatment. Results The PD, PLI, SBI and MD indexes of the two groups were improved after treatment. Compared with the control group, the observation group improve obviously （P 〈 0. 05 ） ; AS the extension of treatment, the PD, PLI, SBI and MD index of observation group gradually improve, curative effect at the time point 8 weeks was better than 4 weeks （ P 〈 0. 05）. Curative effects of control group at 8 weeks and 4 weeks were no statistical difference （ P 〉 0. 05 ）. Conclusions Periodontic - endodonic treatment has ideal efficacy for severe Deriodontitis. and worth of clinical application.
