Physical properties of clinical utility of the new endodontics sealant cements based on silicates. Bibliographic review

Resumen

Introduction: The obturation of the duct system plays a key role in the success of endodontic treatment. In an attempt to improve the properties of sealants cements, silicate-based sealants have recently been introduced to the market. Therefore, when carrying out the sealing of the duct system, it is useful to know the physical properties that the cement sealants present. Objective: The objective of this work was to review the literature of the useful clinical physical properties that the new silicatebased cements present, and to compare them with the physical properties of the conventional epoxy resin-based cements. Material and method: After establishing the adapted research question, a literature review was carried out in two databases (Medline via Pubmed and Wiley Library via Chrocane Library) combining MeSH terms (Medical Subject Headings) and free terms. In addition, a manual electronic search was carried out. The useful clinical physical properties selected were discoloration, sealing capacity, radiodensity, setting time and solubility. Results: 224 potential studies were obtained. Finally, applying the inclusion and exclusion criteria, 22 studies were included in the review. The different studies compared the different physical properties of silicate-based cements, comparing them with resin-based cements. Conclusions: Between silicate-based cements and resin cements, no differences in tooth discoloration were observed. Nor differences were observed in sealing in most of the studies consulted. All the cements analysed presented radiodensity values within the recommended standards. Both the setting time and the solution depended on the type of cement evaluated. Some of the silicate-based cements showed higher solubility compared to resin-based cements.
