A Comparative Evaluation of Sealing Ability of Endosequence Bc Sealer and Proroot Mta as Root Canal Sealer: An Ex Vivo Study

Abstract

BACKGROUNDThe most common method of obturation uses semisolid material such as gutta-percha in combination with a root canal sealer. The sealers must preferably stimulate the process of apical and periapical repair along with providing a hermetic seal. MATERIALS AND METHODSA total of 38 single rooted freshly extracted mandibular teeth were selected and divided into two groups with 15 samples each; Group A (obturated with EndoSequence BC sealer) and Group B (obturated with ProRoot MTA ) and 4 samples each were used for positive control and negative control groups. Sealing ability of the two sealers was evaluated using Microbial Leakage test. RESULTSThe results of the study showed that 5 samples leaked in Group A (33.33%) and 6 samples leaked in Group B (40%). The results of this study suggest that the percentage of specimens without leakage was higher for Group A when compared with Group B. Moreover, early leakage was observed in samples with ProRoot MTA than with EndoSequence BC sealer. However, on applying Mann-Whitney test, the difference was found to be statistically insignificant. Hence, it can be inferred that 'EndoSequence BC Sealer' has comparable sealing ability as compared to 'ProRoot MTA'. CONCLUSIONIt may be concluded that 'EndoSequence BC Sealer' being antibacterial, hydrophilic, bioactive, biocompatible, aluminium-free nanoparticulate bioceramic sealer having superior handling characteristics may be recommended for clinical use. However, before any definite conclusion can be drawn, meticulous studies, a larger number of samples and clinical evaluation for longer duration should be encouraged to evaluate the efficacy of these sealers and potential for achieving the hermetic seal. BACKGROUNDEndodontic sealers are necessary to seal the space between the dentinal walls and the obturating core interface. Moreover, sealers fill the voids and irregularities in the root canal, lateral and accessory canals, and spaces between core materials.Recently, challenges in handling properties of sealers have now been met with the new 'EndoSequence bioceramic sealer' composed of zirconium oxide, calcium silicates, calcium phosphate monobasic and calcium hydroxide along with filler and thickening agents. Since the literature is deficient as regard the sealing ability of EndoSequence bioceramic sealer, the purpose of this study is to evaluate and compare the sealing ability of 'EndoSequence BC sealer (Brassler, Savannah, GA)' in comparison with white 'Pro-Root MTA (Dentsply, Tulsa Dental, Johnson City, USA)' when used as a root canal sealer in an ex vivo study.

Comparative Analysis of Microleakage Associated with Various Endodontic Sealers: An in-vitro Study

“…Also, Remy et al [3] compared AH Plus, Endofill, and MTA Fillapex sealers for their marginal adaptation and sealing ability and observed that AH Plus has better marginal adaptation compared to other sealers used. Jasrotia et al [4] compared the apical sealing ability of three dissimilar endodontic sealers using the dye penetration method under the stereomicroscope and found that dye penetration was least for Ceraseal and Epiphany sealer and highest for AH Plus suggesting that better sealing were observed with Ceraseal bioceramic sealer and epiphany.…”

Comparative Assessment of Root Canal Sealer’s Apical Sealing Ability

“…Root canal sealer should precisely seal the root canal laterally and apically; achieving good adaptation to radicular dentin and fill the voids and irregularities (4) .Hence, root canal sealer contributes to the formation of a strong single cohesive bonding (5) between the dentinal tubules of root canal wall and gutta-percha by achieving monoblock bonding (6) .These properties are desirable requirement that strengthen and prolong the clinical longevity of the root filled tooth as a result of providing a fluid impervious seal (7) Monoblock bonding is beneficial outcome that increases the sealing ability due to avoidance of undesirable gaps formation (6) ; and prevent residual bacteria from recontamination of the root canal system (1) Otherwise, gaps favor leakage resulting in recontamination and failure of the endodontic treatment (8) Epoxy resin sealers are widely used and AH Plus has been considered the gold standard root canal sealer. But, it still has limitations, including mutagenicity, inflammatory reaction and hydrophobicity in addition to advantages of calcium silicate sealers including stability, biocompatibility and hydrophilicity (9) .…”
