Endodontic irrigants negatively influence the physical properties of dentine. The effect of sodium hypochlorite and ethylenediaminetetraacetic acid (EDTA) on the bond strength to dentine was investigated in a systematic review. Inclusion criteria were the following: a microtensile or microshear test, the irrigants sodium hypochlorite and/or EDTA, an irrigation time of ≥ 5 minutes of sodium hypochlorite, an irrigation protocol for endodontic treatment, human dentine, the presence of a control group and no post space preparation. Of the 188 eligible articles, 13 were suitable for inclusion. There was strong evidence that rinsing with sodium hypochlorite and also additional rinsing minutes with ethylenediaminetetraacetic acid leads to minimum bond strength to dentin for a two-step self-etching adhesive. For a two-step etch-and-rinse adhesive, the bond strength is approximately significant after rinsing with sodium hypochlorite (rinsing time: 10-60 minutes).
根管冲洗剂会对牙本质的物理性能产生负面影响。一项系统评价研究了次氯酸钠和乙二胺四乙酸（EDTA）对牙本质粘结强度的影响。纳入标准如下：微拉伸或微剪切试验、冲洗剂次氯酸钠和/或EDTA、次氯酸钠冲洗时间≥5分钟、根管治疗冲洗方案、人牙本质、存在对照组且未进行桩腔预备。在188篇符合条件的文章中，有13篇适合纳入。有强有力的证据表明，用次氯酸钠冲洗以及额外用乙二胺四乙酸冲洗几分钟会导致两步自酸蚀粘结剂与牙本质的粘结强度最低。对于两步酸蚀冲洗粘结剂，用次氯酸钠冲洗后（冲洗时间：10 - 60分钟）粘结强度大致显著。
