Pulp capping

Pulp capping is a technique used in dental medicine to prevent the dental pulp from dying, after being exposed, or nearly exposed during a cavity preparation. When dental caries is removed from a tooth, all or most of the infected and softened enamel and dentin are removed. This can lead to the pulp of the tooth either being exposed or nearly exposed which causes pulpitis (inflammation). Pulpitis, in turn, can become irreversible, leading to pain and pulp necrosis, and necessitating either root canal treatment or extraction of the tooth. The ultimate goal of pulp capping or pulp therapy is to maintain the vitality of the pulp.

Types of Pulp Capping

There are two types of pulp capping - the direct pulp capping and the indirect pulp capping.

Direct Pulp Capping

In direct pulp capping, a material is placed directly over the exposed pulp to promote the formation of reparative dentin and maintain pulp vitality. It is used only when the pulp exposure is small and the pulp is not inflamed.

Indirect Pulp Capping

In indirect pulp capping, a layer of biocompatible material is placed over a thin layer of affected dentin that is not removed in order to avoid pulp exposure. The goal is to allow the remaining affected dentin to remineralize and prevent pulp exposure.

Materials Used in Pulp Capping

Various materials can be used for pulp capping, including calcium hydroxide, mineral trioxide aggregate, and Biodentine. These materials have different properties and are chosen based on the specific needs of the patient and the clinical situation.

Prognosis

The prognosis for pulp capping is generally favorable, but it depends on several factors, including the size and location of the pulp exposure, the material used for pulp capping, and the patient's overall health.
