This study presents a systematic review with meta-analysis to evaluate the success rates of endodontic retreatments in teeth where separated instruments are located within the roots. The search and selection of studies were conducted across two databases, SCOPUS and PubMed, as well as the Cochrane Library registry, yielding a total of 1620 records. Following the selection process, 11 studies were included in the systematic review. Overall, out of 1133 retreated teeth, there were 172 failures in instrument removal and 55 perforations. The meta-analysis results indicate that failures are more frequent when instruments are located in the apical third, with a failure rate of 21%, compared to an 8.8% failure rate in the middle/coronal third. The anatomy of the root canals, particularly the location of the separated instruments, significantly influences the success rates.
本研究进行了一项系统评价并荟萃分析,以评估根管内存在分离器械的牙齿进行根管再治疗的成功率。研究检索与筛选在两个数据库(SCOPUS和PubMed)以及Cochrane图书馆注册库中进行,共获得1620条记录。经过筛选过程,11项研究被纳入系统评价。总体而言,在1133颗接受再治疗的牙齿中,器械取出失败172例,穿孔55例。荟萃分析结果表明,当器械位于根尖三分之一时,失败更为常见,失败率为21%,而在中/冠三分之一的失败率为8.8%。根管的解剖结构,特别是分离器械的位置,对成功率有显著影响。
