• Calcium release stimulates hydroxyapatite and secondary dentin bridge formation
• Alkaline pH promotes healing and apatite formation
• Significant calcium release leads to a protective seal
• Protects and insulates the pulp
• Moisture tolerant and radiopaque – can be placed under restorative materials and cement.

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, cement, 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.

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.

Clinical Significance:

• The proprietary formulation of TheraCal LC consists of tri-calcium silicate particles in a hydrophilic monomer that provides significant calcium release making it a uniquely stable and durable material as a liner or base.

Storage:

• Store at room temperature (20°C/68°F - 25°C/77°F)

1. Pulp Exposures (Direct Pulp Capping)

• Under rubber dam isolation, complete cavity preparation.
• Control bleeding by placing a sterile cotton pellet dampened with sterile saline. Blot
  preparation with cotton pellet. Leave visibly moist.
• Apply TheraCal LC directly to the exposed pulp in incremental layers. The layer is not to exceed 1 mm in depth. Cover all the exposed areas and extend TheraCal LC at least 1 mm onto sound dentin surrounding the exposure. Light cure between layers.
• Light cure each increment for 20 seconds. Place desired adhesive, base, and/or restoration following manufacturer’s directions. Continue restoring the tooth.

2. Deep Preparations (Indirect Pulp Capping), Large Preparations (Liner), Base or Sealer

• Isolate the tooth and perform conventional cavity preparation. Remove all infected carious tooth structures. Leave preparation visibly moist.
• Apply TheraCal LC directly to the cavity floor of the preparation in incremental layers. The layer is not to exceed 1 mm in depth. Manipulate into a smooth surface covering all deep dentin areas. Light cure between layers.
• Light cure each increment for 20 seconds. Place desired adhesive, base, and/or restoration following manufacturer’s directions. Continue restoring the tooth.

Question) What are the differences and similarities between TheraCal LC and Mineral Trioxide Aggregate (MTA) material?

Answer: 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 is 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 pH, and the calcium release assists in the formation of dentin bridge.
