Aim: The purpose of this study was to compare the flow abilities of four different root canal sealers namely, AH Plus, mineral trioxide aggregate (MTA) Fillapex, Sealapex, and Adseal. Materials and Methods: According to the method proposed by International Organization for Standardization (ISO) specification 6876/2012 (root canal sealing materials), a volume of 0.05 ml of the cement was taken and mixed according to the manufacturer's recommendation and placed on a glass plate. At 180 ± 5 s after mixing, the second glass plate of 20 g was placed on top of the sealer, followed by the weight of mass 100 g to make a total mass on the plate of 120 ± 2 g. After 10 min from the start of mixing, the weight was removed and the diameter of the compressed disc of sealer was measured. The mean of five such values for each sealer was taken as the flow of the material. Results: The flow obtained for the sealers are as follows: 21.84 mm for Adseal, 20.01 mm for AH Plus, 22.43 mm for MTA Fillapex, and 19.84 mm for Sealapex. The results were expressed as arithmetic means, and the statistical analysis was then performed for the mean values using ANOVA and Tukey's tests using SPSS 16.0 and a value of <0.05 was considered significant. Conclusion: All the sealers tested conform to ISO specification that requires that a sealer should have a diameter of not < 20 mm. The MTA Fillapex achieved the greatest flow being statistically significant in comparison to other tested sealers (= 0.002), while Sealapex showed the least flow among all.
