中重度牙体缺损根管治疗后嵌体修复的疗效观察

Observation on curative effect of inlay repair after root canal therapy for moderate to severe tooth defects

目的探讨中重度牙体缺损根管治疗后嵌体修复的临床疗效。方法选取2015年3月-2016年12月期间在我院行完善根管治疗的90例中重度牙体缺损患者作为研究对象,随机分为对照组和观察组,各45例。观察组采用高嵌体修复根管治疗后牙牙体缺损,对照组采用全冠修复,观察两组患者修复效果和满意度,并统计修复后牙齿松动和牙周炎发生率。结果观察组修复体优良率(95.56%)与对照组比较,无显著差异P<0.05。观察组术后牙齿松动(2.22%)和牙周炎发生率(2.22%)显著低于对照组(17.78%,15.56%),组间差异P<0.05。观察组修复后满意度(95.56%)显著高于对照组(82.22%),组间差异P<0.05。结论中重度牙体缺损根管治疗后高嵌体修复较好,与全冠修复效果相似,但是其可最大限度牙体组织,且修复后牙齿松动和牙周炎风险较低,患者满意度更高,可作为首先修复方法。

Objective To investigate the clinical curative effect of inlay repair after root canal therapy for moderate to severe tooth defects. Methods A total of 90 patients with moderate to severe tooth defects who underwent root canal therapy in our hospital from March 2015 to December 2016 were randomly divided into control group and observation group. The rats in the observation group were treated with high inlay repair root canal, and the control group was treated with the crown. The repairing effect and satisfaction of the two groups were observed, and the incidence of tooth loosening and periodontitis after the restoration was counted. Results The excellent and good rate of repair group （95.56%） was no significant difference compared with the control group （P 〈0.05）. The incidence of postoperative tooth loosening （2.22%） and periodontitis （2.22%） was significantly lower in the observation group than in the control group （17.78%, 15.56%）. The satisfaction rate （95.56%） in the observation group was significantly higher than that in the control group （82.22%）. The difference between the groups wasp 〈0.05. Conclusion The high inlay repair is better in the treatment of moderate and severe tooth defects after root canal treatment, but it is similar to the effect of crown restoration, but it can maximize the tooth tissue, and the risk of tooth loosening and periodontitis after repair is lower, the patient satisfaction is more High, can be used as the first repair method.
