All endodontic instrumentation systems tested so far, promote apical extrusion of debris, which is one of the main causes of postoperative pain, flare ups, and delayed healing.
Of this meta-analysis was to collect and analyze studies quantifying apically extruded debris while using Hand ProTaper (manual), ProTaper Universal (rotary), Wave One (reciprocating), and self-adjusting file (SAF; vibratory) endodontic instrumentation systems and to determine methods which produced lesser extrusion of debris apically.
An extensive electronic database search was done in PubMed, Scopus, Cochrane, LILACS, and Google Scholar from inception until February 2016 using the key terms "Apical Debris Extrusion, extruded material, and manual/rotary/reciprocating/SAF systems." A systematic search strategy was followed to extract 12 potential articles from a total of 1352 articles. The overall effect size was calculated from the raw mean difference of weight of apically extruded debris.
Statistically significant difference was seen in the following comparisons: SAF < Wave One, SAF < Rotary ProTaper.
Apical extrusion of debris was invariably present in all the instrumentation systems analyzed. SAF system seemed to be periapical tissue friendly as it caused reduced apical extrusion compared to Rotary ProTaper and Wave One.
迄今为止测试的所有根管治疗器械系统都会促使碎屑向根尖方向挤出，这是术后疼痛、炎症发作和愈合延迟的主要原因之一。
本荟萃分析旨在收集和分析使用手用ProTaper（手动）、ProTaper Universal（旋转）、Wave One（往复）和自调式锉（SAF；振动）根管治疗器械系统时量化根尖挤出碎屑的研究，并确定能减少碎屑向根尖方向挤出的方法。
从数据库建立至2016年2月，在PubMed、Scopus、Cochrane、LILACS和谷歌学术中进行了广泛的电子数据库搜索，使用关键词“根尖碎屑挤出、挤出物质和手动/旋转/往复/SAF系统”。遵循系统的搜索策略，从总共1352篇文章中提取出12篇潜在文章。根据根尖挤出碎屑重量的原始平均差异计算总体效应量。
在以下比较中观察到统计学上的显著差异：SAF < Wave One，SAF < 旋转ProTaper。
在所有分析的器械系统中，碎屑向根尖方向的挤出总是存在的。SAF系统似乎对根尖周组织友好，因为与旋转ProTaper和Wave One相比，它导致的根尖挤出减少。
