Calcium silicate cements have been used as dental materials for more than twenty years; however, their use in restorative dentistry is more recent. Better mechanical properties and shorter curing times make them suitable for a variety of applications in which they are used as a substitute of dentin, including direct/indirect pulp capping and as cavity base/liner. These materials may also be used to restore enamel temporarily. This article seeks to review the available scientific evidence with a focus on their applications in restorative dentistry. The information was gathered by reviewing original scientific research articles and literature reviews published in journals available in databases such as Medline/Pubmed and Scielo, along with technical information provided by the manufacturers of these cements. This article describes the composition, instructions for use, and curing reaction of calcium silicate cements, as well as the scientific evidence on their applications in restorative dentistry.Corral-Núñez C, Fernández-Godoy E, Martin-Casielles J, Estay J, Bersezio-Miranda C, Cisternas-Pinto P et al.

RESUMEN.Los cementos de silicato de calcio se han aplicado como materiales dentales desde hace más de veinte años; sin embargo, su uso en el área de la odontología restauradora es más reciente. Mejores propiedades mecánicas y menores tiempos de endurecimiento le permiten ser indicados para una variedad de aplicaciones en las que este material se utiliza como sustituto dentinario, entre ellas el recubrimiento pulpar directo/indirecto y como base/liner cavitario. A su vez, también se podría utilizar como material para restaurar esmalte de manera temporal. El presente artículo busca revisar la evidencia científica disponible, enfocándola a sus aplicaciones en odontología restauradora. La información se obtuvo a partir de artículos originales de investigación científica y revisiones de literatura, publicados en revistas disponibles en bases de datos como Medline/Pubmed y Scielo, junto a la información técnica otorgada por los fabricantes de estos cementos. El presente trabajo describe la composición, el modo de empleo, la reacción de fraguado y la evidencia científica sobre las aplicaciones de los cementos de silicato de calcio en odontología restauradora.Palabras clave: cementos de silicato, cementos dentales, materiales dentales, recubrimiento de la pulpa dental.Corral-Núñez C, Fernández-Godoy E, Martin-Casielles J, Estay J, Bersezio-Miranda C, Cisternas-Pinto P et al Revisión del estado actual de cementos de silicato de calcio en odontología restauradora.

Objective: The aim of this study was to evaluate the effectiveness of cleansing protocols to remove sealer residues using different cleaning strategies and the effect of bond strength of two universal adhesives to dentin impregnated with epoxy resinbased sealer.Materials and Methods: Fifty bovine dentin specimens were impregnated with epoxy resin-based sealer containing calcium hydroxide (Sealer Plus) and submitted to cleansing protocols (n = 10): negative control (NC), positive control (PC), 95% ethanol (ET), xylol (XI), and amyl acetate (AA). Specimens were evaluated by scanning electron microscope (SEM). Other 100 specimens were submitted to the same protocols (n = 20). Each protocol was divided into subgroups (n = 10) according to the universal adhesive system used: Scotchbond Universal (SU); Ambar Universal (AU). Bond strength was evaluated by micro-shear bond test (μSBT). Persistence of residues data were assessed with Kruskal-Wallis and Dunn's tests. μSBT data were analyzed with two-way ANOVA (α = 5%).Results: ET presented higher persistence of residues compared to AA and XI (p < 0.05). AA and XI were similar from each other (p > 0.05). AU and SU presented similar μSBT values, regardless of the cleansing solution (p > 0.05). SU-NC presented the highest μSBT among all conditions (p < 0.05). Conclusion:The bond strength of universal adhesives was not affected by different amounts of sealer residues after different cleaning protocols.Clinical Significance: Non-polar substances such as amyl acetate and xylol are effective for removing residues from epoxy resin-based endodontic sealers.
