“…The results obtained with the epoxy-resinbased sealer may be associated with its low shrinkage during the setting phase, as well as its long-term dimensional stability. 28,29 While it is evident that the bond strength values obtained herein are too low in terms of root reinforcement, endodontic materials with low bond strength to dentin should still be considered good if they are effective in preventing microleakage. 30 Thus, provided that the sealing efficiency of a calcium silicate-based sealer without a main core is shown to be superior to those of the current sealer + core root filling systems, the concept of using a calcium silicate-based sealer in bulk can be more easily advocated in clinical practice.…”

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.

“…Therefore, when evaluating a new sealer, its sealing ability must be examined under different conditions. The smear layer modifies the sealing properties of root canal sealers (22). The composition of the iRoot SP and MTA Fillapex sealers is similar to that of MTA (6).…”

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)

“…This fact, allied to the cohesion among sealer molecules, increases the resistance to removal and/or displacement from dentin, which can be translated as greater adhesion (24)(25)(26) . These results were in agreement with previous study comparing bond strength of a calcium silicate-based sealer tested in bulk or with different main core materials,and showed that IRoot SP and AH plus showing a high dislodgement resistance in push-out test than of MTA Fillapex (27) .…”

Dentin Bond Strength Evaluation of Three Root Canal Sealers with Cold Gutta-Percha Lateral Obturation Technique: Push-Out Test Study

2017

Aim: This study was designed to evaluate dentin bond strength by push-out test of three root canal sealers (IRoot SP, AH Plus, and MTA Fillapex endodontic sealers) with cold gutta-percha lateral obturation technique using push-out test. Methods: A total of 57 human freshly extracted mandibular premolar teeth for orthodontic reason were used in this study. All samples were decoronated 16±1mm from the apex and prepared using step-back technique up to master apical file # 40. The specimens were divided randomly into three groups (19 teeth each) according to the type of sealers used; Group 1(IRoot SP), Group 2(AH Plus sealer), and Group 3 (MTA Fillapex sealer). Each group was obturated with cold gutta-percha lateral obturation technique. The specimens were incubated for 7 days at 37 o C with 100% humidity. Three sections of 2 mm thickness were obtained at 3, 7 and 11mm from the apex to represent apical, middle and coronal third respectively. The push-out bond strength was determined for each root slice. Values were recorded, tabulated for each group and statistically analyzed. Results: IRoot SP showed the highest mean value of push-out bond strength (7.3±0.2), followed by AH Plus (6.8±0.1) while MTA Fillapex showed the lowest mean value of push-out bond strength (2.9±0.3). Conclusions: IRoot SP and AH plus sealers had greater resistance to push-out than MTA Fillapex sealer.
