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 patient is recalled periodically to monitor the progress of the root-end closure, and decide whether other measures root-end paexogenesis may be required. In turn, the walls of the root canal will thicken, and the tooth will become stronger. If the pulp heals, no additional treatment will be necessary. 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.
When an immature tooth is affected by caries or trauma, the pulp requires proper management according to the degree of inflammation and its vitality. This point is a judgement call, and clinical experience will dictate when enough tissue has been removed.
If the exposure was carious, or the traumatic exposure crown fracture, exposed pulp is longer than 24 hours, then the coronal apexogeness tissues are too inflammed to survive a simple capping procedure. In this case, the unhealthy pulp is removed.
Apexogenesis / Apexification
This procedure encourages the root to continue development as the pulp is healed. 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 dental pulp is an ectomesenchymally derived connective tissue with certain unique properties such as being encased in hard tissues, which limits its collateral circulation.
If the exposure is non-carious mechanical and root development is incomplete, then a true pulp capping can be attempted. Drexel Hill, PA In addition to immune cells, the dental pulp contains odontoblasts, which are specialized cells capable of producing dentin.
Apexogenesis This procedure encourages the root to continue development as the pulp is healed. Maintenance of pulp vitality will allow continued root development along the entire root apexogeneeis.
Treatment options: apexogenesis and apexification.
If the pulp is irreversibly inflamed or necrotic, root-end closure procedures are required when the apex has not fully formed. This article will describe requirements for case selection and review the procedures for apexogenesis and apexification in immature permanent teeth.
The more mature the root becomes, the better the chance for the survival of the tooth. The pulp provides a matrix for binding of its cells and provides support allowing apexitication between the cells.
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. Nonclinical and clinical data will be presented to support the recommendations, and outcomes will be presented from clinical studies.
If the tissues are bleeding too profusely, the MTA will be washed away; this would be an apexogeneesis that the tissues remaining are still too inflammed to cap. In the absence of a vital pulp, dentin deposition is arrested. Published by Elsevier Inc.
