Introduction:

theraCal is a new light-curing resin-modified calcium silicate cavity liner and base material designed to act as a barrier and protect the dentin-pulp complex. The precise placement of TheraCal allows it to be used in deep cavities.

Objective:

to describe the usefulness of TheraCal as a protector of the dentin-pulp complex in direct and indirect pulp capping.

Methods:

48 articles on the subject were consulted, obtained from PubMed/MedLine, Google Schoolar, Elsevier, SciELO, information from several repositories of the Autonomous University of Baja California was included and 21 were used as bibliographies, predominantly articles published during the last five years and others due to their relevance.

Development:

the release of the components of TheraCal, especially tricalcium silicate, stimulates the formation of a secondary dentin bridge. It is indicated for use as a direct pulp capping agent by placing directly on pulp exposures once hemostasis has been achieved and as an indirect pulp capping agent in deep preparations, as a protective liner in extensive preparations, and as a base or sealer for use. It is used in resin, amalgam and cement restorations, in addition to being a desensitizer.

Conclusions:

to be successful as a dentin-pulp protector, a hermetic and permanent sealing of the cavity must be achieved, which prevents the entry of microorganisms and reinfection, since the diffusion of toxins through the walls of the restoration to the pulp causes pulp damage and not the material itself.
