Direct Pulp Capping in Primary Teeth | Pediatric Dentistry.
Hello Guys, Here You can Understanding dentistry in an easier and simpler way. Today we are going to see about Direct Pulp Capping in Primary Teeth.
What is Direct Pulp Capping?
While doing Indirect Pulp Capping, we all know enamel and dentin are thinner in primary teeth. And the Pulp horns in the primary teeth are bigger in size and located close to the occlusal surface compared to the permanent teeth. So, there is a high chance of exposing or damaging the pulp while doing tooth preparations. In this scenario, the pulp is exposed by the means of mechanical exposure. Also, there is a chance for pulp is exposed due to trauma. If the pulpal exposure is less than 1mm it is indicated for Direct Pulp Capping. Here direct pulp capping, the pulp is only exposed only by either mechanical or traumatic way, not by caries and the pulp is still vital. The main objective of direct pulp capping is to restore the pulp vitality and enhance the formation of dentin in the exposed area.
Where we can do direct pulp capping (Indications)?
It is indicated, where there is pinpoint exposure of the pulp up to 1mm. Due to exposure, there is the presence of bleeding, if the bleeding is controlled it is indicated for direct pulp capping otherwise it is contraindicated. Within 24hrs of the traumatic exposure of the pulp.
Where we don't do direct pulp capping (Contraindication)?
If the pain exists in the nighttime. Presence of tooth mobility in the exposed tooth. Presence of uncontrolled bleeding in the exposed site. Usually, direct pulp capping is contraindicated in primary teeth because of internal resorption. Because calcium hydroxide causes necrosis of the superficial pulp and it further causes resorption.
What is the material used for the direct pulp capping?
The material we used is calcium hydroxide Ca(OH)2. It is directly applied over the exposed pulp. It has the property to form a calcified bridge/ barrier over the pulp. It took 1 month to form the bridge and the thickness of this bridge increases over the 1 year. And it protects the pulp behind the bridge and makes it vital. This is how calcium hydroxide makes the pulp vital.
Procedures in Direct Pulp Capping
Isolation of the exposed tooth is done by a rubber dam. Then the exposed cavity is irrigated with the saline and bleeding is stopped by placing the cotton pellet. Place the capping material over the exposed pulpal surface. Then place the temporary restoration over the capping material. A permanent restoration is done after determining the success of pulp capping by determining the pulpal health, bridge formation, and inflammatory response.
