目的观察热牙胶充填根管后即刻行纤维桩修复残冠的临床疗效及其应用价值。方法选择福田区人民医院2009年1月至2011年1月口腔科根管治疗后行桩核冠修复的残冠98颗牙,随机分为两组,实验组在3D热牙胶进行根管充填后即刻行桩道预备,对照组在根管治疗后一周行延迟的残冠纤维桩修复,比较两组患者术后的临床疗效。结果两组患者根管三维充填致密,无台阶形成,无根管偏移、无侧穿等并发症发生。两组病例术后1 d均没有三级疼痛出现,术后1周内实验组出现2例出现疼痛症状,疼痛发生率为3.9%,对照组出现4例疼痛症状,疼痛发生率为8.5%,两组比较差异有统计学意义,实验组的疼痛发生率显著低于对照组(P<0.05),纤维桩冠修复分别于术后6个月、12个月、18个月、24个月复查,实验组术后6个月、12个月、18个月、24个月的成功率分别为100%、98.0%、98.0%、96.1%,对照组术后6个月、12个月、18个月、24个月的成功率分别为100%、95.7%、95.7%、91.5%。随着手术时间的延长,实验组的成功率极高,但两组比较差异无统计学意义。结论根管治疗后即刻行残冠纤维桩修复疼痛反应较轻,热牙胶充填根管能达到严密的三维充填效果,操作简单,省时,术后成功率较高,值得在临床推广应用。
Objective To observe the clinical effect and application value of repairing residual crown with fiber post immediately after hot-tooth glue filling. Methods Futian District People’s Hospital from January 2009 to January 2011 dental root canal treatment of post-crown restoration crown 98 residual teeth, were randomly divided into two groups, the experimental group in the 3D hot tooth glue root canal filling The postplot was prepared immediately, and the control group was given a one-week post-root canal treatment to repair the residual fiber crown. The postoperative clinical efficacy was compared between the two groups. Results The three-dimensional filling of root canal in both groups was dense, with no step formation, no root canal deviation and no complications of lateral wear. There was no grade 3 pain in both groups at 1 d after operation. Pain was found in 2 cases in experimental group within 1 week after operation. The incidence of pain was 3.9%. In the control group, 4 cases showed pain and the pain rate was 8.5% The difference between the two groups was statistically significant, the incidence of pain in the experimental group was significantly lower than that of the control group (P <0.05), and the post-treatment of the fiber post crown was reviewed at 6 months, 12 months, 18 months and 24 months after operation , The success rates of the experimental group at 6 months, 12 months, 18 months and 24 months after operation were 100%, 98.0%, 98.0% and 96.1% respectively in the experimental group, 6 months, 12 months and 18 months after the operation in the control group Months, 24 months success rates were 100%, 95.7%, 95.7%, 91.5%. With the extension of operation time, the success rate of the experimental group was extremely high, but there was no significant difference between the two groups. Conclusions The post-root canal treatment of residual fiber crown post-operatively relieves the pain reaction. The filling of root canal with hot-dentin can achieve a close three-dimensional filling effect. The operation is simple, time saving and high success rate after operation. It is worthy of clinical application.
