Biodentine: um substituto ao MTA? / Biodentine: an alternative to MTA?

Objetivo: o objetivo desse estudo é realizar uma revisão de literatura em relação às propriedades físico- -químicas e biológicas do Biodentine, seu emprego na Endodontia e discutir, com base nas evidências científicas encontradas na literatura, se esse material poderá ser um substituto ao MTA. Métodos: foi realizada uma busca na literatura na base de dados PubMed, usando os termos em inglês: Biodentine, calcium silicate, MTA, properties, setting time, radiopacity, solubility, physicochemical properties, porosity, hydration, biocompatibility, bioactivity, microhardness, compressive strength, bond strength, irrigants, furcal perforation, retrograde filling material, revitalization, revascularization, endodontics, apexification. Cinquenta artigos foram incluídos. Resultados: os artigos revisados sugerem que o Biodentine tem características favoráveis e que tem alcançado resultados promissores em relação ao MTA. Conclusão: o Biodentine pode ser considerado um eventual substituto ao MTA (AU).

Introduction: This study aim to review the literature about the physicochemical and biological characteristics of Biodentine, a cement used in endodontics, and discussed whether this material might be an alternative to MTA according to the scientific evidence found in the literature. Methods: A literature search was performed on PubMed using the following terms: Biodentine, calcium silicate, MTA, properties, setting time, radiopacity, solubility, physicochemical properties, porosity, hydration, biocompatibility, bioactivity, microhardness, compressive strength, bond strength, irrigants, furcal perforation, retrograde filling, revitalization, revascularization, endodontics, apexification. Fifty studies met inclusion criteria. Results: Biodentine seems to have favorable characteristics, and the results of its use are promising when compared with those of MTA. Conclusion: Biodentine may be a possible alternative to MTA (AU).

Effect of previous irrigation with chlorhexidine on the push-out bond strength of a calcium silicate-based material.

This study evaluated the effect of previous irrigation with chlorhexidine (CHX) on the bond strength of a calcium silicate-based material, Biodentine, when used for furcal repair. Furcal perforations were produced in 30 extracted mandibular molars. Teeth were divided into 3 groups according to the irrigant used: distilled water (DW), CHX followed by DW (CHX), and CHX followed by ethylenediaminetetraacetic acid (EDTA) and DW (CHX/EDTA). Biodentine was used to repair the perforations. A push-out bond strength test was performed after 7 days, and data were statistically analyzed using Kruskal-Wallis and Dunn tests (P < 0.05). The CHX/EDTA group showed significantly lower values than the DW and CHX groups (P < 0.05). The failure mode of the DW group was mainly mixed, while that of the CHX group was cohesive. The CHX/EDTA group exhibited adhesive and mixed failures. Irrigation with CHX prior to furcation repair did not result in a statistically significant difference, compared to the use of DW, in the push-out bond strength of Biodentine.
