چکیده

Background and aims: AH۲۶, Master-Dent, and Endoseal mineral trioxide aggregate (MTA) are three different types of sealers. The purpose of this study was to assess and compare THE apical seal of the root canal-treated teeth with the above-mentioned sealers in the presence and absence of moisture using the fluid filtration method. Methods: To this end, ۵۴ freshly extracted single root canal human canines were selected for this study. The canals were prepared using rotary instruments, and then sodium hypochlorite was applied as an irrigation solution in this protocol. The specimens were randomly divided into three groups of ۱۸. One group was obturated with the gutta-percha by the cold lateral compaction technique. Half of one of the aforementioned sealers belonged to the group of moistened teeth and the other half to the group of the dried teeth. Microleakage in all groups was assessed ۳ months after the obturation of canals by the fluid filtration method. The data were analyzed using ANOVA and Tukey’s post hoc tests, and the level of significance was set at P < ۰.۰۵. Results: The results showed that the minimum and maximum micro-leakage belonged to Masterdent dry (mean leakage = ۱.۷۷۷۸ μL/ min/CmH۲۰) and Endoseal-MTA dry (mean leakage = ۳.۵۰۰۰ μL/min/CmH۲۰), respectively. All three groups of sealers exhibited a significant difference in apical micro-leakage between dry and moist conditions (PMasterdent < ۰.۰۰۱, PAH۲۶ = ۰.۰۰۲, and PEndoseaL-MTA = ۰.۰۰۷). Conclusion: The findings of this experimental study demonstrated that Masterdent provided the least apical micro-leakage under dry conditions while Endoseal-MTA had the highest micro-leakage under these conditions. There was a significant difference between dry and moist conditions in all groups.
