Two different types of pulp cap are distinguished. In direct pulp capping, the protective dressing is placed directly over an exposed pulp; and in indirect pulp capping, a thin layer of softened dentin, that if removed would expose the pulp, is left in place and the protective dressing is placed on top.

It can be used for root-end filling material and as pulp capping material. It has better pulpotomy outcomes than calcium hydroxide or formocresol, and may be the best known material, as of 2018 data. [1] For pulp capping, it has a success rate higher than calcium hydroxide, and indistinguishable from Biodentin. [2]
Due to its physical properties and biocompatibility, MTA has been used in numerous clinical situations other than as a root-end filling. It is widely used to repair perforations, to close open apices in apexification, as a direct pulp capping material for deep carious tooth, and to cover pulp stumps for apexogenesis.
Direct pulp capping (DPC) is a treatment performed when a pin-point or small pulp exposure of 1mm or less occurs after removal of carious tooth material (dentin) excavation. The pulp is covered with a medicament.
They are commonly used as pulp capping agents and lining materials for silicate and resin-based filling materials. [3] Calcium-silicate liner used as a pulp capping material. It is usually supplied as two pastes, a glycol salicylate and another paste containing zinc oxide with calcium hydroxide. On mixing, a chelate compound is formed.
Conventional root canal therapy cleans and fills the pulp chamber with biologically inert material after destruction of the pulp due to dental caries, congenital deformity or trauma. Regenerative endodontics instead seeks to replace live tissue in the pulp chamber. The ultimate goal of regenerative endodontic procedures is to regenerate the ...

Indirect restorations are contraindicated in patients under 16 as the pulp chamber is still large and wide dentinal tubules increase the stress on the pulp. When preparing a cavity to retain an indirect restoration there is a risk of damage to the nerve supply of a vital tooth.
