“…In the latter form (i.e., bulk), iRoot SP was recently shown to perform similarly to a epoxy resin-based sealer and significantly better than calcium hydroxide-and methacrylate resin-based sealers in terms of radicular push-out bond strength. 12 However, no information is available regarding its adhesive strength when used with a core filling material and whether its dislocation resistance in conjunction with a core material is superior to that of its bulk-filled form as well as to that of other root filling systems. Thus, the aim of this study was to evaluate the radicular push-out bond strength of a calcium silicate-based sealer with or without different core filling materials in comparison with commonly used sealer + core filling systems.…”

Bond strength of a calcium silicatebased sealer tested in bulk or with different main core materials Abstract: The aim of this study was to evaluate the influence of a calcium silicate-based sealer (iRoot SP), with or without a core material, on bond strength to radicular dentin, in comparison with various contemporary root filling systems. Root canals of freshly extracted singlerooted teeth (n = 60) were instrumented using rotary instruments. The roots were randomly assigned to one of the following experimental groups: (1) a calcium silicate-based sealer without a core material (bulk-fill); (2) a calcium silicate-based sealer + gutta-percha; (3) a calcium silicate-based sealer + Resilon; (4) a methacrylate resin-based sealer (RealSeal SE) + Resilon; (5) an epoxy resin-based sealer (AH Plus) + gutta-percha, and (6) a mineral trioxide aggregate-based endodontic sealer (MTA Fillapex) + gutta-percha. Four 1-mm-thick sections were obtained from the coronal aspect of each root (n = 40 slices/group). Push-out bond strength testing was performed at a cross-head speed of 1 mm/min, and the bond strength data were analyzed statistically by one-way analysis of variance and Tukey tests (p < 0.05). The highest and lowest debonding values were obtained for the calcium silicate-based sealer bulk-fill and mineral trioxide aggregate-based endodontic sealer + gutta-percha groups, respectively (p < 0.05). It was concluded that the calcium silicate-based sealer showed higher resistance to dislocation in the bulk-filled form than in conjunction with the tested core filling materials. When the calcium silicate-based sealer was placed in bulk, its dislocation resistance was similar to that of commonly used sealer + core root filling systems. Thus, the concept of using a calcium silicatebased sealer in bulk can be more easily advocated in clinical practice.

“…25 The adhesive strength of endodontics cements has been frequently examined by the push-out method. 10,21 However, the tendency of the gutta-percha to deform when a compressive load is applied during testing is a problem of the push-out test. 26 Another problem is the risk of contact of the gutta-percha with the dentinal wall.…”

Aim: This study investigated the flowability, setting time, pH, calcium release and bond strength of a MTA-based cement (MTA Fillapex ® ) compared to AH Plus and Sealapex. Materials and methods:For the flowability test, the ISO 6876:2001 specification was utilized and for the setting time test, the ASTM C266-03 specification was utilized. For the pH and calcium release measurements, 10 samples were prepared for each group and analyzed for several different periods. For the push-out test, dentin disks were distributed into three groups, according to the cement utilized and into three subgroups, according to the root third (n = 10). After obturation, the specimens underwent push-out testing. The data were compared statistically using a significance level of 5%. Results:The flowability of all materials was found to be similar (p > 0.05). The setting times were different among the groups tested (MTA Fillapex < Sealapex < AH Plus) (p < 0.05). At days 7 and 28, the MTA Fillapex presented the higher pH values (p < 0.05). At 24 hours and at 14 days, the calcium release of the MTA Fillapex was similar to that of Sealapex (p > 0.05). AH Plus presented the lowest pH and calcium release values (p < 0.05). In all root thirds, the adhesion to the dentin of the MTA Fillapex and Sealapex were significantly lower than that of AH Plus (p < 0.05). Conclusion:MTA Fillapex and Sealapex presented several similar properties and both were found to be different than AH Plus.Clinical significance: This study evaluated the physicochemical and mechanical properties of new MTA-based root canal cement, in order to use this scaler in root canal fillings. MTA Fillapex showed satisfactory properties for clinical use.

“…iRoot SP hardens in the presence of water and does not shrink during setting (6). The manufacturer claims that iRoot SP has both hydrophilicity and adhesiveness and chemically bonds to root canal walls (8). Thus, microleakage might be less for iRoot SP than for MTA Fillapex.…”

“…iRoot SP (Innovative BioCeramix, Vancouver, Canada) is a premixed, readyto-use, injectable white cement paste that is described by its manufacturer as an insoluble, radiopaque, aluminumfree material composed of calcium, calcium phosphate, calcium hydroxide, and zirconium oxide similar to that of white mineral trioxide aggregate (MTA). iRoot SP exhibits cytocompatibility and antibacterial activity (6,7), with satisfactory sealing ability (6) root canal dentin (8).…”

We compared the apical seals of two new calcium silicate-based sealers (iRoot SP and MTA Fillapex) in the presence and absence of a smear layer. Eighty-two human premolars were prepared and randomly divided into four groups. In groups 1 and 3, the smear layer was retained. In groups 2 and 4, the root canals were irrigated with EDTA to remove the smear layer. Canals were filled using gutta-percha/iRoot SP (in groups 1 and 2) or obturated with gutta-percha/MTA Fillapex (in groups 3 and 4). Fluid filtration was used to evaluate apical microleakage. The presence of the smear layer had no significant effect on the sealing properties of the filling materials, except for iRoot SP at 2 weeks (P = 0.007). There was significantly less microleakage with iRoot SP than with MTA Fillapex (P = 0.025 at 2 weeks; P < 0.001 at 3 months). Leakage decreased significantly over time in all specimens, except in group 2 (P = 0.473). In conclusion, removal of the smear layer had no adverse effect on the sealing properties of calcium silicate-based sealers. In addition, the sealing ability of iRoot SP was superior to that of MTA Fillapex. (J Oral Sci 56, 215-219, 2014)
