简介：　　 【摘要】 目的：探讨一次性根管治疗牙体牙髓病效果及对咀嚼功能的影响。方法：选择 2018年 5月 -2019年 5月笔者所在医院接收的牙体牙髓病患者 92例，根据随机数字表法分为两组，各 46例。对照组采用多次根管治疗，观察组采用一次性根管治疗。对比两组临床疗效、咀嚼功能及并发症情况。结果：治疗后，观察组总有效率高于对照组，咀嚼效率及咬合力均优于对照组，并发症发生率低于对照组，差异均有统计学意义（ P<0.05）。结论：应用一次性根管治疗牙体牙髓病效果更佳，可有效改善咀嚼功能，加强咬合力，减少术后并发症。  　　 【关键词】 牙体牙髓病 一次性根管治疗 咀嚼功能  　 Objective: To investigate the effect of one-time root canal therapy on dental pulp disease and masticatory function. Methods: from May 2018 to may 2019, 92 patients with endodontic disease in our hospital were selected and randomly divided into two groups, 46 cases in each group. The control group was treated with multiple root canal therapy, and the observation group was treated with one-time root canal therapy. The clinical efficacy, masticatory function and complications were compared between the two groups. Results: after treatment, the total effective rate of the observation group was higher than that of the control group, the masticatory efficiency and bite force were better than those of the control group, the incidence of complications was lower than that of the control group, the differences were statistically significant (P < 0.05). Conclusion: the effect of one-time root canal treatment on dental pulp disease is better, which can effectively improve masticatory function, strengthen bite force and reduce postoperative complications.
