There have been several studies conducted on the success rates of direct and indirect pulp capping using a range of different materials. One study of indirect pulp capping recorded success rates of 98.3% and 95% using bioactive tricalcium silicate [Ca3SiO5]-based dentin substitute and light-activated calcium hydroxide [CA(OH)2]-based liner ...
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.
Some caries excavation methods lead to leaving caries-affected dentin behind to serve as the bonding substrate, mostly in indirect pulp capping. It is reported that the immediate bond strengths to caries-affected dentin are 20-50% lower than to sound dentin, and even lower with caries-infected dentin. [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.
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. This material possesses great sealing ability, good antimicrobial activity, great biocompatibility, and enhances dentin biomineralization. [5]
Mineral trioxide aggregate (MTA) is an alkaline, cementitious dental repair material. MTA is used for creating apical plugs during apexification, repairing root perforations during root canal therapy, and treating internal root resorption. It can be used for root-end filling material and as pulp capping material.
In dentistry, a crown or a dental cap is a type of dental restoration that completely caps or encircles a tooth or dental implant. A crown may be needed when a large dental cavity threatens the health of a tooth.
Non-eugenol materials use long-chain aliphatic acids or aryl-substituted butyric acid to react with zinc oxide particles. [1] Eugenol itself is known to be incompatible with resin polymers, [ 23 ] as it is a radical scavenger (like other phenolic compounds ) and therefore inhibits polymerisation of resin materials.
