[摘要]目的：探究根管治療联合树脂对牙体缺损合并慢性根尖周炎的修复效果。方法：选取2018年2月-2020年2月笔者医院科室收治的113例牙体缺损合并慢性根尖周炎患者进行研究，根据治疗方式不同分为观察组（58例）和对照组（55例），其中对照组采用根管治疗加玻璃离子修复，观察组在根管治疗基础上加用树脂修复。治疗3个月后，观察两组修复效果、疼痛发生率、不良反应及患者对本次治疗的满意度。结果：治疗3个月后，观察组修复有效率94.29%，高于对照组的70.00%，差异具有统计学意义（P<0.05）;观察组患者疼痛发生率13.79%，高于对照组的5.45%，但两组比较差异无统计学意义（P>0.05）;观察组总不良反应发生率8.57%，低于对照组的47.14%，差异具有统计学意义（P<0.05）;观察组总满意度86.21%，高于对照组的65.45%，差异具有统计学意义（P<0.05）。结论：根管治疗联合树脂对牙体缺损合并慢性根尖周炎修复效果较好，且疼痛和不良反应发生率均较低，患者对治疗满意度较好。

Abstract：Objective  To explore the effect of root canal therapy combined with resin on the restoration of dental defects with chronic apical periodontitis. Methods Between February 2018 and February 2020，113 patients with tooth defects and chronic periapical periodontitis in our hospital were enrolled. According to different treatment methods， they were divided into observation group （58 cases） and control group （55 cases）. The control group received root canal therapy， and the observation group was treated with resin on the basis of the control group. After 3 months of treatment， the restorative effect， pain incidence， adverse reactions， and patients satisfaction were recorded in both groups. Results After 3 months of treatment， the restoration efficiency in the observation group was higher than that in the control group（94.29% vs. 70.00% ， P<0.05）. After 3 months of treatment， the incidence of pain in the observation group was higher than that in the control group （13.79% （8/58） vs. 5.45% ， P>0.05）. After 3 months of treatment， the incidence of total adverse reactions in the observation group was lower than that in the control group （8.57%  vs. 47.14%， P<0.05）. After 3 months of treatment， the total satisfaction of the observation group was higher than that of the control group （86.21% vs. 65.45% ， P<0.05）. Conclusion  Root canal therapy combined with resin is effective in repairing tooth defects and chronic periapical periodontitis with low incidence of pain and adverse reactions and high satisfaction.

牙体缺损容易导致牙髓炎和根尖周炎，造成牙折裂、牙体颜色改变，牙龈炎伴出血等不良后果，不利于患者牙齿健康及美观，且伴随慢性根尖周炎，使治疗难度增大[1]。临床常规治疗方式为根管治疗，但患者牙质会发生改变，为保障远期疗效，牙冠修复在临床治疗中具有重要地位[2]。大面积缺损牙体修复易受其修复方法及材料影响，对患牙咀嚼功能与邻牙紧密度存在一定负面影响。如何有效选择修复方法和材料对患者至关重要[3]。既往研究表示，根管治疗效果受到临床广泛认可，但会损伤牙组织韧性及硬度，有效的填充材料可弥补根管治疗的间隙，发挥保护作用[4]。聚合树脂是临床常用填充材料，外观可行、操作方便，可有效提高牙体抗力[5]。……
