摘　　要：目的评价超声大块树脂修复乳磨牙根管治疗后牙体缺损的临床疗效。方法选择乳磨牙行根管治疗的患儿78例(共126颗患牙),按患儿就诊顺序随机分为观察组40例(64颗患牙)和对照组38例(62颗患牙)。观察组患儿根管治疗后采用SonicFill超声充填树脂,对照组患儿根管治疗后采用Filtek Z350树脂充填,比较两组充填操作时间、术后满意度以及6个月、12个月时修复体的完整度、边缘密合度、边缘着色情况。结果观察组平均操作时间低于对照组,差异有统计学意义(P<0.05)。治疗后两组患儿家属的满意度比较差异无统计学意义(P>0.05)。治疗6个月、12个月时两组患儿在完整度、边缘密合度、边缘着色方面比较差异均无统计学意义(P>0.05)。结论超声大块树脂应用于乳磨牙牙体缺损的短期充填效果较理想,且缩短了充填操作时间,为儿童牙体治疗提供了更优的选择。Objective To observe the clinical effect of ultrasonic bulk resin in restoration of primary molar defect after root canal therapy.Methods Totally 78 children(126 primary molars) were included in the study, and they were randomly divided into two groups according to their visit to the hospital: 40 children(64 molars) in observation group and 38 children(62 molars) in control group. In observation group, the children were treated with SonicFill ultrasonic resin after root canal therapy, while the children in control group received Filtek Z350 resin after root canal therapy. The operation time, satisfaction after surgery, and the integrity, edge fitness and staining at 6 and 12 months after treatment were compared between the groups.Results The operation time of experimental group was lower than that of control group, there was significant difference between two groups(P<0.05).There was no significant difference between the two groups in postoperative satisfaction degree(P>0.05). There was no significant difference between the two groups in integrity, edge fitness or staining after a follow-up of 6 months and 12 months(P>0.05).Conclusion Ultrasonic bulk resin in restoration of primary molar defect after root canal therapy can get superior clinical effect in a short time, and the operation time is shortened. It provides a better choice for resin filling in the tooth therapy for children.
