Farrugia C, et al. - Authors characterized new light-curable tricalcium silicate–based pulp capping materials and compared their surface and antimicrobial properties with clinically available Theracal (Bisco, Schaumburg, IL) and Biodentine (Septodont, Saint-Maur-des-Fossés, France). Findings suggested that the antimicrobial properties of a material are affected by its surface characteristics. Comparable antimicrobial properties with other light-curable pulp capping agents were exhibited by the experimental resin-modified materials.
