This study aimed to compare the effects of ethylenediaminetetraacetic acid (EDTA) and maleic acid (MA) on the sealing ability of various root canal sealers. Eighty root canals were instrumented and irrigated with either EDTA or MA. They were divided into eight experimental groups and obturated as follows: Group 1: MA + Hybrid Root SEAL/gutta-percha. Group 2: EDTA + Hybrid Root SEAL/gutta-percha. Group 3: MA + iRoot SP/gutta-percha. Group 4: EDTA + iRoot SP/gutta-percha. Group 5: MA + EndoREZ/EndoREZ points. Group 6: EDTA + EndoREZ/EndoREZ points. Group 7: MA + AH Plus/gutta-percha. Group 8: EDTA + AH Plus/gutta-percha. Another ten roots were used as negative and positive controls. The microleakage of each sample was measured at 2-min intervals for 8 min using the fluid filtration method. Data were statistically analyzed with one-way ANOVA, post-hoc Tukey, and paired-samples t tests. The minimum microleakage values were obtained from the teeth obturated with AH Plus and EndoREZ selaers (p < 0.001). The samples with Hybrid Root SEAL showed the maximum leakage (p < 0.001). There were significant differences between the groups irrigated with MA or EDTA in terms of microleakage (p < 0.05). Use of MA resulted in higher microleakage values compared with those using EDTA. The type of final irrigation solution seems to influence the postobturation apical seal. Use of AH Plus and EndoREZ sealers showed better sealing ability compared with IRoot SP and Hybrid Root SEAL.
本研究旨在比较乙二胺四乙酸（EDTA）和马来酸（MA）对各种根管封闭剂封闭能力的影响。80个根管分别用EDTA或MA进行预备和冲洗。它们被分为8个实验组并按以下方式进行充填：第1组：MA + Hybrid Root SEAL/牙胶尖。第2组：EDTA + Hybrid Root SEAL/牙胶尖。第3组：MA + iRoot SP/牙胶尖。第4组：EDTA + iRoot SP/牙胶尖。第5组：MA + EndoREZ/EndoREZ尖。第6组：EDTA + EndoREZ/EndoREZ尖。第7组：MA + AH Plus/牙胶尖。第8组：EDTA + AH Plus/牙胶尖。另外10个牙根用作阴性和阳性对照。使用流体过滤法每隔2分钟测量每个样本8分钟的微渗漏情况。数据采用单因素方差分析、事后Tukey检验和配对样本t检验进行统计学分析。最低微渗漏值来自用AH Plus和EndoREZ封闭剂充填的牙齿（p < 0.001）。使用Hybrid Root SEAL的样本显示出最大的渗漏（p < 0.001）。在微渗漏方面，用MA或EDTA冲洗的组之间存在显著差异（p < 0.05）。与使用EDTA相比，使用MA导致更高的微渗漏值。最终冲洗液的类型似乎会影响充填后根尖封闭。与IRoot SP和Hybrid Root SEAL相比，使用AH Plus和EndoREZ封闭剂显示出更好的封闭能力。
