“…iRoot SP has a composition similar to that of white mineral trioxide aggregate composed of calcium silicate, calcium phosphate, calcium hydroxide, and zirconium oxide, and has superior physical, antibacterial, and biocompatibility properties. [9][10][11][12][13][14] Another new tricalcium silicate-based sealer (MTA Fillapex; Angelus, Londrina, Brazil) composed of radiopaque bismuth, nanoparticulated silica, MTA, and pigments has been introduced recently as an endodontic filling material. According to the manufacturer, MTA Fillapex has excellent radiopacity, easy handling, excellent working time, and low solubility, enhancing sealing through expansion during setting.…”

Fracture resistance of roots obturated with a novel calcium silicate-based endodontic sealer (ABSTRACT The aim of this ex vivo study was to evaluate the vertical-fracture resistance of roots obturated with a newly developed tricalcium silicate cement (BioRoot RCS; Septodont, Saint Maur Des Fosses, France) using cold lateral compaction technique (LC) or matchedtaper single-cone gutta-percha technique (SC). Decoronated 82 single-rooted mandibular premolars were chemo-mechanically prepared and then randomly divided into 6 experimental groups (n = 12) and 2 control groups (n = 5): Group 1 iRoot SP-LC; Group 2 iRoot SP-SC; Group 3 MTA Fillapex-LC; Group 4 MTA Fillapex-SC; Group 5 BioRoot RCS-LC and Group 6 BioRoot RCS-SC. In the positive-control group, roots were instrumented but not filled, and in the negativecontrol group, roots were neither instrumented nor filled. All samples were incubated for two weeks and then subjected to vertical loading force (1 mm/min) until fracture. The force required to fracture each specimen were determined, and the data were statistically analyzed. The highest significant fracture resistance was recorded for the iRoot SP-LC, iRoot SP-SC, BioRoot RCS-LC, and BioRoot RCS-SC groups, with no significant difference among them (p > 0.05) when compared with the positive-control group (p < 0.05), whereas the lowest significant values were observed in the MTA Fillapex-LC and MTA Fillapex-SC groups (p < 0.05). The vertical fracture resistance of roots obturated with BioRoot RCS and iRoot SP sealers using either LC or SC technique was found to be similar to that of intact teeth. BioRoot RCS, newly developed tricalcium silicate cement, might have the potential to reinforce the instrumented teeth against vertical root fracture.

“…These results may possibly be explained by the reinforcement provided by the sealer used, in this case AH Plus (Ulusoy et al . ), and the resistance provided by the filling material, in this case Gutta‐percha (Ulusoy et al . , Kazandag et al .…”

“…Ulusoy et al [29] compared the effects of these two root canal sealers on fracture resistance of simulated immature teeth and observed that both iRoot SP and Hybrid Root SEAL reinforced the simulated immature roots against fracture when used with either Gutta-percha or resilon equally. Both the sealers though based on different setting mechanisms have shown promising clinical results as endodontic sealers, as confirmed by various studies.…”

Objective:The objective was to compare the sealing ability of two root canal sealers viz.: Hybrid Root SEAL (Sun Medical, Tokyo, Japan) and iRoot SP (Innovative BioCeramix Inc., Vancouver, Canada). Materials and Methods: A sample of 60 permanent single rooted, human maxillary central incisors of similar sizes was selected for the study. The teeth were decoronated and randomly divided into two groups viz.: Group A and Group B, comprising of thirty teeth each. In Group A, Hybrid Root SEAL and Group B, iRoot SP were used as root canal sealers along with Gutta-percha cones using lateral condensation technique to obturate the canals. After obturation roots were covered with nail paint except 2.0 mm of root and stored in 0.5% methylene blue dye for 1 week. The teeth were immersed in 10 ml of 65% nitric acid for complete dissolution and subsequently subjected to UV spectrophotometer to quantify the concentration of the dye in each sample. The data were analyzed using the unpaired t-test. Results: The mean dye leakage value in Group B (0.368) was less as compared to Group A (0.408). However, statistically the difference was nonsignifi cant (P = 0.053). Conclusion: There was no statistically signifi cant difference among the two groups.
