Uses of TheraCal: An Applied Study

Abstract

EL TheraCal is a new base and lining material filled with light-curing resin-modified calcium silicate, thus achieving control of hardening time, designed as direct and indirect pulp capping, with approximately 45% by weight of mineral material, 10% of radiopaque component, 5% hydrophilic thickening substance and approximately 45% resin.The release of these components, especially that of tricalcium silicate, stimulates the formation of a secondary dentin bridge, hydroxyapatite. Furthermore, when released, they are in the concentration range for the possible stimulating activity of the dental pulp and odontoblasts. They are used in resin, amalgam and cement restorations, as well as being a sensitizer. It addresses certain advantages such as allowing a seal and a strong adherence, apart from the fact that its use considerably reduces pulpal death.Pulp capping attempts to maintain the vitality of the pulp, which can be based mainly on applying medication directly to the exposed pulp, calling this procedure direct pulp capping, or choosing to apply a sealer or choosing to apply used under restorative materials, cements. or other residual base materials being called indirect pulp capping.Comparative studies have been conducted between SCMR and other materials used in pulp capping, where it has been determined that TheraCal has the ability to release more calcium ions. Another characteristic attributed to TheraCal is that it forms an alkaline pH of 10-11, but returns to neutral pH within a short period of 3 days. This type of indirect pulp capping has a specific clinical behavior for the procedure of acute and strong caries wounds, mainly in adolescent patients, with symptoms that correspond to a pulp with a potentially reversible state, without visibly exposing the pulp.
