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 pulp provides a matrix for binding of its cells and provides support allowing communication between the cells.
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. 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. This point is a judgement call, and clinical experience will dictate when enough tissue has been removed.
Treatment options: apexogenesis and apexification.
The dental pulp is an ectomesenchymally derived connective tissue with certain unique properties such as being encased amd hard tissues, which limits its collateral circulation.
This article will describe requirements for case selection and review the procedures for apexogenesis and apexification in immature permanent teeth.
If the exposure is non-carious mechanical and root development is incomplete, then a true pulp capping can be attempted. In turn, the walls of the root canal will thicken, and the tooth will become stronger. 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.
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 more mature the root becomes, the better the chance for the survival of the tooth. Maintenance of pulp vitality will allow continued root development along the entire root length. In the absence of a vital pulp, dentin deposition is arrested.
Apexogenesis / Apexification
Drexel Hill, PA In addition to immune cells, the dental pulp contains odontoblasts, which are specialized cells capable of producing dentin. Nonclinical and clinical data will be presented to support the recommendations, and outcomes will be presented from clinical studies.
The patient apexogenessi recalled periodically to monitor the progress of the root-end closure, and decide whether other measures root-end surgery may be required. In this case, the unhealthy pulp is removed.
If the pulp heals, no additional treatment will be necessary. 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. Published by Elsevier Inc. This procedure encourages the root to continue development as the pulp is healed.
The coronal paexification 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. 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.
