摘要
目的 比较生物陶瓷材料(iRoot BP Plus)牙髓切断术与根管治疗术治疗龋源性露髓乳磨牙的疗效.方法 选取安徽医科大学合肥口腔临床学院(合肥市口腔医院)2021年9月至2022年3月收治的符合研究对象纳入标准的患牙62颗,采用简单随机分配的方法均分为两组(牙髓切断组和根管治疗组),每组31颗牙,分别采用iRoot BP Plus牙髓切断术和根管治疗术进行治疗.术后6、12、18个月复查,观察比较两组治疗的成功率.结果 术后6、12、18个月治疗的成功率,牙髓切断组分别为 100.0％(31/31)、100.0％(31/31)、96.8％(30/31),根管治疗组分别为 100.0％(31/31)、93.5％(29/3 1)、80.6％(25/31),牙髓切断组术后12个月及18个月治疗的成功率均高于根管治疗组,且术后18个月时两组治疗的成功率差异有统计学意义(x2=4.02,P＜0.05).结论 iRoot BP Plus牙髓切断术相较于根管治疗术治疗龋源性露髓乳磨牙的效果更理想和稳定.
Abstract
Objective To investigate the efficacy of iRoot BP Plus pulpotomy versus root canal therapy for the management of cariously exposed pulp in deciduous molars.Methods A total of 62 teeth from eligible patients who received treatment at Hefei Stomatological Clinical College(Hefei Stomatological Hospital),Anhui Medical University between September 2021 and March 2022 were selected for the study.These teeth were randomly treated either with iRoot BP Plus pulpotomy(pulpotomy group,n=31)or root canal therapy(root canal therapy group,n=31).Follow-up examinations were conducted at 6,12,and 18 months post-treatment to compare the success rates of treatment between the two groups.Results The success rates of treatment at 6,12,and 18 months post-treatment in the pulpotomy group were 100.0％(31/31),100.0％(31/31),and 96.8％(30/31),respectively,while in the root canal therapy group,they were 100.0％(31/31),93.5％(29/31),and 80.6％(25/31).The success rates in the pulpotomy group were significantly higher than those in the root canal therapy group at both 12 and 18 months post-treatment,with a statistically significant difference observed at 18 months(x2=4.02,P＜0.05).Conclusion The iRoot BP Plus pulpotomy procedure yields a more favorable and stable outcome compared with root canal therapy for managing cariously exposed pulp in deciduous molars.
