It is a light-cured, resin-based, and highly radiopaque liner designed to release calcium to promote hard-tissue formation, and is indicated for use under direct restorative materials as a replacement to calcium hydroxide and other calcium silicate-based materials, glass ionomers, eugenol-based sedative materials, and pulp capping restoratives. TheraCal LC exhibits several properties to help maintain ideal hard-tissue health and to reduce the incidence of postoperative sensitivity. This article is aimed to review the composition, method of application, setting reaction, properties and uses of TheraCal LC. Conclusion: TheraCal LC is interesting and promising product, which have the potential of creating major contributions to maintaining pulp vitality.

Introduction Primary objective of restorative dentistry is to preserve pulpal health of vital teeth. 1 For the modern approach in restorative dentistry, the major challenge is to induce the remineralization of hypomineralized carious dentine, and thus, protecting and preserving the vital pulp. 2 Traditionally, management of deep caries often resulted in pulp exposure and subsequent root canal treatment. But nowadays, management strategies for the treatment of the cariously exposed pulp are shifting with avoidance of pulpectomy, claiming the superiority of vital pulp treatment (VPT) techniques such as pulp capping, partial and complete pulpotomy. 2 Various bioactive materials introduced into the dentistry in last few decades which showed promising results in pulp capping. * Corresponding author. E-mail address: kalyaniumale@gmail.com (K. G. Umale). Calcium silicate-based materials like MTA, Biodentin and MTA derived materials are proved to be bioactive and shows several properties like: 1. Antibacterial activity 2. Property of reparative dentine formation. 3. Maintain pulp vitality. 4. Establishing a tight bacterial seal. 5. Resist forces during restoration placement and function. 6. Adhere to dentine as well as the restoration. 7. Radiopacity 8. Prevent post-operative sensitivity by sealing the dentinal tubules. 3 Recently various Calcium silicate-based materials are introduced in dentistry which are bioactive materials as they are capable of forming apatite by using calcium silicates or calcium aluminates. 1 In the last decade, calcium silicate based hydraulic cement, known as Mineral https://doi.org/10.18231/j.adr.2021.019 2277-3401/© 2021 Innovative Publication, All rights reserved. 112
