Calcium Silicate-Based Experimental Sealers: Physicochemical Properties Evaluation

Calcium Silicate-Based Experimental Sealers: Physicochemical Properties Evaluation

Abstract The aim of this study was to evaluate physicochemical properties of calcium silicate-based experimental (CS) endodontic sealers, developed using two different vehicles: polyethylene glycol (PG) (CS-PG) or polyethylene glycol associated to chitosan hydrogel (CS-PGCH). TotalFill BC Sealer (TF) and AH Plus (AHP) were evaluated for comparison. Setting time, flow, radiopacity, pH, solubility and volumetric change were analyzed. Data were submitted to ANOVA and Tukey tests with 5% significance level. The CS-PGCH had significantly greater setting time. CS-PG flow was similar to AHP. CS-PG had higher radiopacity than CS-PGCH. Calcium silicate-based sealers presented alkaline pH in all periods. CS-PGCH presented higher solubility in comparison with CS-PG. The volumetric change of CS-PG was similar to TF after 7 days, and to AHP after 30 days. CS-PG presented proper setting time, radiopacity, flow and pH, besides low volumetric change, showing better results than CS-PGCH, and potential for clinical application.
