TheraCal LC by Bisco

TheraCal LC® is used for direct and indirect pulp capping and as a protective liner under composites, amalgams, cements, and other base materials. The light-cured, resin-modified calcium silicate filled material is an alternative to calcium hydroxide, glass ionomer, RMGI, IRM/ZOE, and other restorative materials.

TheraCal LC exhibits several properties to help maintain ideal hard-tissue health and to reduce the incidence of postoperative sensitivity. Its calcium release stimulates hydroxyapatite and secondary dentin bridge formation^1-3 while creating a seal that protects⁴ and insulates the pulp⁵. Additionally, TheraCal LC has an alkaline pH to encourage healing.^1,2,4

TheraCal LC is opaque white to help mask stained dentin and radiopaque for easy follow-up monitoring. TheraCal LC’s proprietary formulation allows for a command set with a light-curing unit while maintaining ease of placement because of thixotropic properties. The light-cured set permits immediate placement of the restorative material. A creamy, spreadable consistency facilitates placement, making TheraCal LC easy to manipulate without running or slumping when undisturbed.
