“…Nurmeisari et al in 2018 (17) , compared the sealing ability of MTA Fillapex and an epoxy sealer and their results showed no statistically significant differences between the two tested groups. They explained these comparable results by the presence of calcium silicate hydrate gel produced from the hydration reaction of MTA Fillapex.…”

“…One of the key factors for the success of any rootend filling material is its ability to create an efficient barrier between the root end filling material and the periapical tissues, in addition to its biocompitability and handling properties (1,2,14) . Different root end filling materials are commercially available; each of them shows some advantages and disadvantages.MTA have been under spot during the past years proving their good physical properties combined with their bioactivity (1,15,17) .…”

“…According to the results of this study; the low microleakage of MTA Fillapex can be attributed to its good flow allowing penetration of the material into the main and lateral root canals and dentinal tubules. The penetration would be facilitated because of the presence of MTA nanoparticles powders and rosins; in addition, MTA capability to form interstitial adherent layer similar to hydroxypatite exhibiting superior marginal adaptation (17) .…”

“…They explained these comparable results by the presence of calcium silicate hydrate gel produced from the hydration reaction of MTA Fillapex. Calcium silicate hydrate gel is sticky and porous allows binding to gutta percha in addition to its high flowability permitting deep penetration into lateral root canals and dentinal tubules (17) .…”

Background: Attempts for preserving endodontically treated teeth after root canal treatment failure have directed the clinicians to surgical intervention; apicectomies with root end resection followed by placement of root-end filling material. Different techniques are used to assess the quality of the apical seal obtained by root end filling materials. Dye penetration is considered the most popular technique. Objective: this in vitro study aimed to evaluate and compare the apical microleakage of three rootend filling materials.Methods: Twenty one upper incisors were utilized, root canals instrumentation was achieved by ProTaper system. Obturation was conducted by lateral condensation technique using Protaper universal gutta percha points. Teeth were apically resected at an angle of 90° to the long axis of the root and root end cavities were prepared and filled. The samples were coated with varnish, then were immersed in 2% methylene blue solution for 24 hours. Roots were then sectioned bucco-lingually in a longitudinal direction. Extent of dye penetration was detected by the use of stereomicroscope.Results: The highest mean value was recorded in MTA group, followed by Guttaflow bioactive and Endoseal groups, where both almost recorded the same mean values. Tukey's post hoc test revealed no statistically significant difference between the three tested groups. Conclusion:It can be concluded that; all the three groups showed microleakage and none of the three root-end filling materials was able to achieve perfect apical seal. The result also showed that guttaflow bioactive provides a similar reliable seal compared to MTA Fillapex and Endoseal MTA.
