“…[24][25][26] Several endodontic filling materials are used to increase the fracture resistance of instrumented root canals. [4,11] Most root canal filling methods recommend a root canal sealer as a complementary part of the obturation technique. An ideal root canal sealer should fill not only the gaps between gutta-percha cones and root canal walls, but also the voids between individual gutta-percha cones applied during obturation of the root canal system.…”

“…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.

“…8 In order to avoid such situations, various endodontic filling materials can be used to reinforce the endodontically treated tooth and improve its fracture resistance. 9,10 In the present study, the effectiveness of Endoseal MTA sealer on fracture resistance was compared with that of AH Plus sealer. The results showed that the fracture resistance of AH Plus and Endoseal MTA sealer reinforced teeth was superior when compared to the fracture resistance of unreinforced teeth (control group).…”

Aim: To evaluate and compare the effect of epoxy resin-based sealer and a pozzolan-based mineral trioxide aggregate (MTA) sealer on the fracture resistance of endodontically treated teeth. Materials and methods:Thirty single-rooted mandibular premolars were decoronated to a standardized root length of 15 mm. ProTaper rotary files up to a master apical file size of F3 were used for cleaning and shaping the root canals followed by 2.5% sodium hypochlorite irrigation. The teeth were randomly divided into three groups (n = 10 each), and the obturation was completed using gutta-percha with Endoseal MTA (group I) and AH Plus (group II) as root canal sealers. Group III served as control (instrumented and unfilled). Each specimen was then subjected to fracture testing by using a universal testing machine at a crosshead speed of 1.0 mm/minute until fracture. The force required to fracture each specimen was recorded and the data were subjected to statistical analysis using one-way analysis of variance (ANOVA), followed by pairwise comparison using post hoc Games-Howell test (p < 0.05). Results:The fracture resistance of groups I and II were significantly higher than those of group III. No significant difference in the fracture resistance was observed between group I (Endoseal MTA) and group II (AH Plus) groups. Conclusion:It can be concluded that the new root canal sealer, Endoseal MTA, is able to reinforce the tooth against fracture as good as AH Plus.Clinical significance: Endoseal MTA is a sealer for the reinforcement of endodontically treated teeth.

“…For fracture strength measurement, in many studies, loading force was applied in a vertical direction because a vertical force applied parallel to the long axis of a tooth produces a more uniform stress distribution. 11,12 Therefore, in the current study, a single load to fracture was applied in the vertical direction with a cross-head speed of 1 mm minute -1 using a universal testing machine.…”

Aim:The purpose of the study was to compare the fracture resistance of roots filled with one of the following five root canal sealers: AH Plus, EndoRez, RealSeal, MTA Fillapex, and AcroSeal. The null hypothesis was that the type of root canal sealer would not influence the fracture resistance of root-filled teeth.Methods: Sixty-five maxillary central incisors were sectioned 1 mm below the cementoenamel junction (CEJ) to obtain roots 14 mm in length. Roots were subjected to chemomechanical preparation using the rotary instruments of the Profile system. The obturation of root canals was performed with the following filling materials (n = 12): group I: AH Plus and gutta-percha (GP), group II: EndoRez and GP, group III: RealSeal and GP, group IV: MTA Fillapex and GP, group V: AcroSeal and GP, group VI: roots were instrumented but not filled (control; n = 5). After the appropriate setting time, each root was embedded in acrylic resin. The specimens were then subjected to fracture resistance testing using an Instron testing machine at 1 mm/min. Conclusion:All of the root canal sealers used in this study increased the fracture resistance of instrumented root canals.
