Abstract：
Accumulated hard tissue debris (AHTD) is an inevitable by-product during endodontic treatment and is difficult to remove completely using traditional syringe and needle irrigation (SNI). Adjunctive irrigation is proposed to assist the clean-up of AHTD. This systematic review and meta-analysis aimed to evaluate the AHTD removal efficacy of different root canal irrigation devices using micro-computed tomography (Micro-CT). A literature search was carried out within the main scientific databases until 20 June 2022. All results were screened with detailed eligibility criteria. Eleven studies were included for analysis. SNI, passive ultrasonic irrigation (PUI), negative pressure systems, sonically activated irrigation (SAI), mechanical-activated system and laser-activated irrigation (LAI) were assessed. PUI is superior to SNI for debris removal and LAI has better AHTD removal performance than PUI. The negative pressure system and mechanical-activated system were proved to be less effective.

摘要：
积聚的硬组织碎片（AHTD）是牙髓治疗过程中不可避免的副产品，使用传统的注射器和针头冲洗（SNI）很难完全清除。建议辅助灌溉以协助AHTD的清理。本系统综述和荟萃分析旨在使用微型计算机断层扫描（Micro-CT）评估不同根管冲洗装置的AHTD去除功效。直到2022年6月20日，在主要科学数据库中进行了文献检索。所有结果均按照详细的合格标准进行筛选。包括11项研究进行分析。SNI,被动超声冲洗（PUI），负压系统,声波激活灌溉（SAI），评估了机械激活系统和激光激活灌溉（LAI）。PUI在去除碎屑方面优于SNI，LAI比PUI具有更好的AHTD去除性能。负压系统和机械激活系统被证明效果较差。注册:PROSPERO(CRD42021273892)。
