“…This is in agreement with previous research that also observed poor bond strength values for MTA Fillapex (16,22,23). This is a paste-to-paste sealer that, whenever mixed, establishes 2 important chemical reactions that are responsible for the material's setting and physical-mechanical characteristics, the progressive hydration of the orthosilicate ions and the reaction between MTA and salicylate resin (26).…”

“…The use of endodontic sealers during root canal obturation yields the sealing between gutta-percha and dentinal walls, acting against bacterial leakage that may lead to endodontic failures (15,16). Every currently available root canal sealer presents limitations regarding the ideal properties of an endodontic sealer (17).…”

“…Results of our study also showed that MTA Fillapex had significantly lower bond strength than AH Plus and EndoSequence BC sealer. Similar results were obtained in a study by Sonmez et al [30] who compared the push-out bond strength of MTA Fillapex with ProRoot MTA and AH Plus. The results of this study are also in accordance with several recent studies which reported lower bond strength of MTA Fillapex in comparison to AH Plus.…”

Background: Sealers are universally used along with gutta-percha to obturate the root canals in three dimensions. Push-out bond strength is considered appropriate to measure the adhesion capacity of sealers. Aim: To compare the bond strength of recently introduced bioceramic sealer with commonly used sealers and to evaluate the effect of plunger: base orifice size ratio on push-out bond strength. Methods: One hundred mandibular premolars with single canals were decoronated and instrumented up to master apical file F3 Protaper. Specimens were randomly divided into four groups (n=25) based on the sealer used: Group 1-EndoSequence BC Sealer, Group 2-MTA FillApex sealer, Group3-Apexit Plus sealer & Group 4-AH Plus sealer and obturated using cold lateral compaction technique. After two weeks, 1±0.1mm thick slice of each radicular third of specimens was subjected to push-out testing with modified and standardised plunger: base orifice size ratio for each slice and bond strength calculated. Subsequently the slices were observed under stereomicroscope for failure mode analysis. Results: Results showed that AH Plus sealer had the highest overall bond strength followed by EndoSequence BC sealer and MTA FillApex while as Apexit Plus had lowest bond strength. Bond strength of all sealers reduced from coronal to apical direction except in EndoSequence BC sealer which showed better strength in critical apical third. Higher bond strength values were obtained due to modified relation of plunger with base orifice size. Conclusion: Bond strength of all sealers tested except EndoSequence BC reduces in apical direction and is impacted by plunger: base orifice size ratio.

“…This sealer is composed of salicylate resin, resin diluent, natural resin, bismuth oxide, silica nanoparticles, and MTA. Its physical properties (11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23) and biocompatibility (24,25) are already known. Nonetheless, to date, no studies have been conducted to analyze histologically the effect of MTA Fillapex in direct contact with bone tissue.…”
