Pulp capping is a technique used in dental restorations to protect the dental pulp, after it has been exposed, or nearly exposed during a cavity preparation, from a traumatic injury, or by a deep cavity that reaches the center of the tooth, causing the pulp to die. [1]
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.
Pulp capping is a method to protect the pulp chamber if the clinician suspects it may have been exposed by caries or cavity preparation. Indirect pulp caps are indicated for suspected micro-exposures whereas direct pulp caps are place on a visibly exposed pulp.
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]
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.
Perform direct or indirect pulp capping [1] in cases with pulpal extension, [2] to try increase the rate of reparative dentin formation (but may result in obliteration of the canal) Seal exposed dentin with microhybrid acid-etched flowable light-cured resin [ 7 ]
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 ...
Preparing a tooth to accept a full coverage crown is relatively destructive. The procedure can damage the pulp irreversibly, through mechanical, thermal and chemical trauma and making the pulp more susceptible to bacterial invasion. [25] Therefore, preparations must be as conservative as possible, whilst producing a strong retentive restoration.
