2种用于根管治疗后牙体修复树脂的临床疗效对比分析

Comparative analysis of clinical efficacy of two kinds of resin for filling repair of maxillary first molar after root canal treatment

目的 观察比较根管治疗后,Z350纳米数脂与sonicfill声波树脂充填修复上颌第一磨牙牙体缺损的临床疗效。方法 将门诊完成根管治疗后并且余留牙体量足够的上颌第一磨牙40颗随机平均分为A、B组,A组采用Z350纳米树脂修复;B组采用sonicfill声波树脂修复。于修复后即刻及12个月对患牙进行检查和随访,参照美国公共卫生署修复体评价标准对其缺损的临床修复效果进行评价。结果 上颌第一磨牙根管治疗后的牙体树脂修复即刻及12月后两组修复效果无显著差异。结论 2种树脂均适用于余留牙体量足够的上颌第一磨牙根管治疗后的牙体缺损修复,其中sonicfill声波树脂充填操作时间明显占优。

Objective To observe and compare the clinical effects of Z350 and sonicfill resin filling in the treatment of maxillary first molar defect.Methods The maxillary first molars were left after the root canal treatment in the outpatient department.Forty samples were randomly divided into group A and group B.Group A was repaired with Z350,while group B was repaired with sonicfill.The two groups of patients were examined and followed up immediately and 12 months after the repair,and the clinical repair effect of the defects was evaluated by referring to the evaluation criteria of the prosthesis of the United States department of public health.Results There was no significant difference between the two groups in the repair effect immediately and 12 months after the treatment of maxillary first molar root canal.Conclusion Both resins are suitable for the repair of dental defects after the treatment of maxillary first molar root canal with sufficient residual tooth volume,in which sonicfill resin filling operation time is obviously superior.
