TheraCal LC is a resin-modified calcium tri-silicate that has enhanced physical properties when compared to MTA material. Essentially, the primary chemical used in both materials are similar (Portland cement) but TheraCal LC contains a patent pending hydrophilic resin, which allows for immediate light curing and facilitates calcium release. Similar to MTA material, TheraCal LC promotes healing due to the alkaline pH1,2, and the calcium release assists in the formation of dentin bridge1,3.
