Very simply, TheraCal LC is 2014 technology and, in my practice, has completely replaced what I think are antiquated systems for pulp capping and lining. There are many reasons why TheraCal LC is a better option than other calcium hydroxide products, MTA, and glass ionomer for deep cavity preps.

All the Benefits?

We know that the gold standard for pulp capping has been calcium hydroxide because of its regenerative and antibacterial properties. TheraCal LC is a resinmodifi ed calcium silicate fi lled material (specifi cally tri-calcium silicate particles in a hydrophilic monomer) that, like other calcium-based materials, releases calcium to stimulate hydroxyapatite and secondary dentin bridge formation. The calcium release leads to a protective seal. Additionally, its alkaline pH promotes healing.

...Without the Negatives

TheraCal LC (Bisco) was developed to address many of the challenges and limitations of other pulp capping/liner materials:

  • Handling?TheraCal LC is supplied in a ready-to-use syringe. It requires no mixing. I describe its use as identical to that of a fl owable composite?except that it stays where you place it.
  • Placement?TheraCal LC is applied directly from the syringe. It?s easily ?painted? across cavity walls by dragging the tip of the syringe through the material. TheraCal LC?s precise placement simplifi es its use in all deep cavity preparations. It?s light-cured, enabling immediate placement of restorative materials.
  • Bonding/sealing?MTA is diffi cult to place, has poor solubility, and does not bond well. TheraCal LC?s proprietary hydrophilic resin formulation creates a stable and durable lining with mechanical adhesive properties to deep, moist dentin.
  • Cost-effective?With an average price point around $30 for a 1-g syringe, TheraCal LC is less expensive than other calcium-releasing liners. When I use it sparingly, I have found I can do a number of pulp cap procedures at a very good value.

Touching a Nerve

I have found TheraCal LC particularly effective in deep cavities with near or complete exposure of the nerve. Although glass ionomers are generally effective base materials because of their fl uoride release, they are not good candidates for these deep near-exposure cases?their acid pH is cytotoxic to the pulp. TheraCal LC is ideal and safe, because its alkaline pH promotes healing.

Additional Benefits

TheraCal LC is highly radiopaque, so I can see it clearly with radiopaque cements and restorative materials on follow-up radiographs. It has great physical properties for longevity, forming a durable protective/insulating barrier over the pulp.

Bottom line, TheraCal LC delivers all the regenerative features and benefi ts of calcium hydroxide and MTA to the nerve?faster and more easily. It?s used like a flowable composite: no mixing, direct and precise application, and command setting with a curing light. TheraCal LC is indispensable in my practice for pulp capping and as a liner and base in deep cavity preps. It saves me time and money while providing a great service to my patients.
