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.

In addition to immune cells, the dental pulp contains odontoblasts, which are specialized cells capable of producing dentin. 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.
Apexogenesis / Apexification
When an immature tooth is affected by caries or trauma, the pulp requires proper management according to the degree of inflammation and its vitality. The pulp provides a matrix for binding of its cells and provides support allowing communication between the cells.
If the exposure is non-carious mechanical and root development is incomplete, then a true pulp capping can be attempted. 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.
This procedure encourages the root to continue development as the pulp is healed.
Treatment options: apexogenesis and apexification.
This article will describe requirements for case selection and review the procedures for apexogenesis and apexification in immature permanent teeth. This point is a judgement call, and clinical experience will dictate when enough tissue has been removed. In turn, the walls of the root canal apexufication thicken, and the tooth will become stronger. 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.
In this case, the unhealthy pulp is removed.
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. The coronal portion of the canal space is then acid-etched, and a bonded composite or galss ionomer is condensed amd the canal to re-enforce the root and provide more sturctural integrity.
Drexel Hill, PA In the absence of a vital pulp, apexohenesis deposition is arrested.
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. 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. Apexogenesis This procedure encourages the root to continue development as the pulp is healed. If the pulp heals, no additional treatment will be necessary.
Nonclinical and clinical data will be presented to support the recommendations, and outcomes will be presented from clinical studies.
APEXOGENESIS / APEXIFICATION – Drexel Hill, PA Endodontist
Maintenance of pulp vitality will allow continued root development along the entire root length. If the pulp is irreversibly inflamed or necrotic, root-end closure procedures are required when ajd apex has not fully formed.
The more mature the root becomes, the better the chance for the survival of the tooth.
