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.

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.
The setting time of biodentine is shorter as compared with that of MTA, In conclusion, this material is clinically indicated for permanent dentin substitute, direct and indirect pulp capping, pulpotomy, repair of furcation and root perforations, retrograde root-end filling, and apexification. [7]
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.
Inlays and Onlays are similar as they are a type of indirect restoration. However, the difference is that Inlays are indirect restorations which do not have cuspal coverage and are within the body of the tooth.(1) Onlays are indirect restorations that cover both body and cusps of teeth. [7] Inlay Indications: [7] Extensively restored or ...
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. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown.
Dental pulp, which is a richly vascularized and innervated tissue, is enclosed by tissues, such as dentin, which are incapable of expanding. It has terminal blood flow and possesses only small-gauge circulatory access at the apical foramen. All of these characteristics severely constrain the defensive capacity of the pulp tissue when faced with ...
