Abstract:
Aim and Objective:
This review focuses on describing the various dentin bridge forming direct pulp capping agent .
Background:
Pulp capping agents are used in dental restorations to prevent the dental pulp from dying, after being exposed, or nearly exposed due to a mechanical exposure. Some commonly used pulp capping agents include Calcium Hydroxide,
Zinc Oxide Eugenol (ZOE) Cement,Corticosteroids and Antibiotics,Collagen,Polycarboxylate cement,Calcium phosphate etc.
Reason:
The success of the pulp capping procedure greatly depends upon the circumstances under which it is performed and the prognosis depends upon the age, type, site and size of pulp exposure. In addition to this the pulp capping material should have the following ideal properties like
* Stimulate reparative dentin formation
* Maintain pulpal vitality
* Release fluoride to prevent secondary caries
* Bactericidal or bacteriostatic
* Adhere to dentin
This review helps to know the various pulp capping agents which can form dentin bridge .
Keywords: dentin bridge, dental caries, pulp capping , pulpitis
INTRODUCTION:
Historically, the first pulp capping procedure was performed in 1756, by the Phillip pfaff, who packed a small piece of gold over an exposed vital pulp to promote healing. However, the success of the pulp capping procedure greatly depends upon the circumstances under which it is performed and the prognosis depends upon the age, type, site and size of pulp exposure.[1]
The consequences of pulp exposure from caries, trauma or tooth preparation misadventure can be severe, with pain and infection the result. The morbidity associated with treating pulp exposures is consequential, often requiring either extraction or root canal therapy.[2]Both the loss of the tooth and its replacement, or endodontic treatment and tooth restoration, involve multiple appointments and considerable expense. An alternative procedure to extraction or endodontic therapy is pulp capping, in which a medicament is placed directly over the exposed pulp (direct pulp cap), or a cavity liner or sealer is placed over residual caries (indirect pulp cap) in an attempt to maintain pulp vitality and avoid the more extensive treatment dictated by extraction or endodontic therapy.[3]
DIRECT PULP CAPPING:
The pulp of a tooth can be exposed due to several causes: caries, trauma or mechanical reasons, the latter typically due to a misadventure during tooth preparation. [4]The direct pulp cap,...
