How one product released a decade ago continues to help group practices reduce postoperative sensitivity

For dentists like Mark L. Cannon, DDS, MS, providing dental services isn’t just a job – it’s a calling. “Dental health professionals care deeply about their patients and do their best to prevent oral and systemic disease,” he said. 

Yet for years, the ability to protect the pulp while reducing sensitivity post-op was a one-two combination that alluded providers. That is until 2011, when BISCO introduced TheraCal LC to the market. 

TheraCal LC is a light-cured, resin-modified calcium silicate filled liner designed for use in direct and indirect pulp capping and as a protective liner under composites, amalgams, cements, and other base materials. It can be used as an alternative to calcium hydroxide, glass ionomer, RMGI, IRM/ZOE and other restorative materials. TheraCal LC performs as a barrier and protectant of the dental pulpal complex.

“What better way to practice dentistry than to routinely use a calcium releasing, alkaline, light cured base that will help protect the pulp and reduce sensitivity?” said Dr. Cannon. 

Since its introduction, TheraCal LC has won numerous industry awards, including several top awards from The Dental Advisor, as well as being a recommended product by The Dental Shopper.

Going deep

Jack D. Griffin Jr., DMD, MAGD, AAACD, ABAD, said his office has found that TheraCal LC works well in particularly tough spots. “In our office we have found that by using TheraCal LC in very deep preparations we have seen a substantial reduction in sensitivity over merely bonding and placing composite in a deep preparation because of its insulating capacity.”

Indeed, TheraCal LC’s precise placement allows its use in all deep cavity preparations. The light-cured set permits immediate placement and condensation of the restorative material. Its proprietary formulation allows for a command set with a light curing unit while maintaining ease of placement due to thixotropic properties. The
proprietary hydrophilic resin formulation creates a stable and durable liner.

Said Cannon: “TheraCal LC is that product and it is easily and precisely placed then light cured. Designed for modern day 21st century dentistry as the base or liner for adhesive resin-based dentistry, TheraCal LC is the first and best in its class!”
