Cobalt Calcium Silicate Based Resin Modified Liner is a urethane acrylate resin-reinforced tricalcium silicate material specifically designed for use as a pulp-protective liner. The high filler content minimizes polymerization shrinkage, resulting in optimal viscosity and handling properties. Its hydrophilic formulation facilitates the formation of a stable and protective layer over the dentin, enhancing its clinical efficacy in preserving pulp vitality.
