Abstract
Introduction: The combination of sol-gel derived calcium silicate particles and glycerol salicylate resins may enhance the pyhisico-chemical properties contribute to the understanding of the interaction between these materials. This study aims to evaluate the physical-chemical properties of resin-based bioactive endodontic cements with glycerol salicylate resins and calcium silicate particles. Materials and methods: Calcium silicate was produced by the sol-gel route, while the resin was produced by mixing 60wt% glycerol salicylate, 30wt% methyl salicylate and 10wt% distilled water. Calcium silicate was added in three different concentrations, 50, 40 and 25% by weight. The cement was tested for setting time, flow, radiopacity and pH. Results: The 50:50 group shows the time of 15min8s while the 75:25 shows the time of 256min13s (p

The combination of sol-gel derived calcium silicate particles and glycerol salicylate resins may enhance the pyhisico-chemical properties contribute to the understanding of the interaction between these materials
Bioactive calcium silicate particles were used in a composite material with a glycerol salicylate resin
The adjustment of flow and radiopacity should be considered for its clinical application
Summary
The combination of sol-gel derived calcium silicate particles and glycerol salicylate resins may enhance the pyhisico-chemical properties contribute to the understanding of the interaction between these materials. The combination of 50wt% calcium silicate particles to 50wt% glycerol salicylate resin showed adequate setting time and promoted an increase in water pH. The water-based calcium silicate materials are the most used bioactive endodontic cements due to their ability to promote biological sealing of damaged dentin and to stimulate cells to proliferate[5] and differentiate[6] resulting in the formation of regenerative tissue in dentin and pulp. The aim of this study is to evaluatethe physical-chemical properties of resin-bases bioactive endodontic cements formulated with glycerol salicylate resins and calcium silicate particles
