Apexogenesis. This procedure encourages the root to continue development as the pulp is healed. The exposed pulpal tissue is covered with a medicament. What is apexogenesis & apexification? Patients with developing teeth may require endodontic intervention to help close the opening at the tip. Multiple techniques and materials have been described for apexogenesis and apexification in immature permanent teeth. Two cases in which.

The more mature the root becomes, the better the chance for the survival of the tooth.

Drexel Hill, PA Nonclinical and clinical data will be presented to support the recommendations, and outcomes will be presented from clinical studies. This point is a judgement call, and clinical experience will dictate when enough tissue has been removed.
A small preparation is made into the dentin overlying the exposure site, using a sterile diamond round bur less potential to tear the pulpal tissue vs. In turn, the walls of the root canal will thicken, and the tooth will become stronger. The coronal portion of the canal space is then acid-etched, and a bonded composite or galss ionomer is condensed into the canal to re-enforce the root and provide more sturctural integrity.
The MTA is sealed with a leak-proof restoration glass ionomer, for example and the patient is recalled at appropriate intervals to re-evaluate healing and continued root development.
If the exposure is non-carious mechanical and root development is incomplete, then a true pulp capping can be attempted. If the pulp heals, no additional treatment will be necessary. In this case, the unhealthy pulp apexificayion removed.
This article will describe requirements for case selection and review the procedures for apexogenesis and apexification in immature permanent teeth. Maintenance of pulp vitality will allow continued root development along the entire root length.
In addition to immune cells, the dental pulp contains odontoblasts, which are specialized cells capable of producing dentin. The pulp provides a matrix for binding of its cells and provides support apexifocation communication between the cells.
The patient is recalled periodically to monitor the progress of the root-end closure, and decide whether other measures root-end surgery may be required.
When an immature tooth is affected by caries or trauma, the pulp requires proper management according to the degree of inflammation and its vitality. Apexogenesis This procedure encourages the root to continue development as the pulp is healed.
If the pulp is irreversibly inflamed or necrotic, root-end closure procedures are required when the apex has not fully formed. Published by Elsevier Inc.
If the exposure was carious, or the traumatic exposure crown fracture, exposed pulp is longer than 24 hours, then the coronal pulpal tissues are too inflammed to survive a simple capping procedure. In the absence of a vital pulp, dentin deposition is arrested.
The dental pulp is an ectomesenchymally derived connective tissue with certain unique properties such as being encased in hard tissues, which limits its collateral circulation. This procedure encourages the root to continue development as the pulp is healed.
If the tissues are bleeding too profusely, the MTA will be washed away; this would be an indication that the tissues remaining are still too inflammed to cap.
