摘　　要：目的 根尖倒充填是显微根尖手术的关键步骤之一,倒充填材料的选择影响手术的预后,本研究旨在评估新型生物陶瓷材料iRoot BP Plus作为根尖倒充填材料在显微根尖手术应用中的近期临床疗效并与三氧化物聚合物(MTA)相比较,以期为临床倒充填材料的选择提供参考。方法 选取2018年12月—2020年12月在安徽省口腔医院牙体牙髓儿童牙病科诊断为慢性根尖周炎需要进行显微根尖手术的患者60例(81颗患牙),在取得患者知情同意后,按照随机数表分为2组,试验组为iRoot BP Plus组29例(39颗患牙),对照组为MTA组31例(42颗患牙),由同一术者按标准化步骤对患者实施显微根尖手术。术后3个月、6个月、1年随访,1年随访时获得的临床和X线评估资料作为疗效评定的主要依据,对2组临床疗效进行评定,并对2组成功率和预后影响因素进行统计学分析。结果 iRoot BP Plus组患者的成功率为92.3%,MTA组为90.5%,差异无统计学意义(P>0.05);影响显微根尖手术疗效的相关因素分析结果显示患者性别、年龄以及牙位之间的比较差异无统计学意义(均P>0.05),尽管病变直径≤10 mm的1年随访成功率较病变直径>10 mm高(95.1%vs. 80.0%),但差异无统计学意义(χ^(2)=2.639,P=0.104)。结论 本研究初步证实了iRoot BP Plus和MTA作为根尖倒充填材料均能取得满意的效果,值得临床推广应用。Objective The root-end filling is one of the key steps of the endodontic microsurgery,and the selection of the root-end filling material affects the prognosis of the surgery.The purpose of this study is to evaluate the short-term clinical efficacy of the new bioceramic material iRoot BP Plus as the root-end filling material in the endodontic microsurgery and compare it with the trioxide polymer(MTA),so as to provide reference for clinical selection.Methods Sixty patients(81 teeth)diagnosed as chronic apical periodontitis with the need for endodontic microsurgery in the Department of Endodontics and Pediatric Dentistry of Anhui Stomatological Hospital from December 2018 to December 2020 were selected.After obtaining the informed consent of the patients,they were randomly divided into two groups through a table of random numbers,the test group was iRoot BP Plus group with 29 patients(39 teeth),and the control group was MTA group with 31 patients(42 teeth).A standardized surgical procedure was performed by a single operator.The patients were followed up at 3 months,6 months,and 1-year.Clinical and radiographic evaluations acquired at the 1-year follow-up were taken as the primary outcome,and the success rate and prognostic factors of the two groups were statistically analyzed.Results The success rate in the iRoot BP Plus and MTA groups were 92.3%and 90.5%,respectively(P>0.05).The analysis of related factors affecting the curative effect of endodontic microsurgery showed that there was no significant difference in gender,age and tooth position(all P>0.05).Although the 1-year follow-up success rate of lesions with diameter≤10 mm was higher than that of lesions with diameter>10 mm(95.1%vs.80.0%),the difference was not statistically significant(χ^(2)=2.639,P=0.104).Conclusion Both iRoot BP Plus and MTA can achieve satisfactory results as root-end filling materials,which are worthy of clinical promotion and application.
