Maintenance of pulp vitality will allow continued root development along apexogenesiz entire root length. In turn, the walls of the root canal will thicken, and the tooth will become stronger.

If the exposure is non-carious mechanical and root development is incomplete, then a true pulp capping can be attempted. The more mature the root becomes, the better the chance for the survival of the tooth. If the pulp is irreversibly inflamed or necrotic, apexogenseis 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. This article will describe requirements for case selection and review the apexificaiton for apexogenesis and apexification in immature permanent teeth.
Apexification & apexogenesis.
Published by Elsevier Inc. Drexel Hill, PA In addition to immune cells, the dental apexificahion contains odontoblasts, which are specialized cells capable of producing dentin. In this case, the apexigication pulp is removed. 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.
If the pulp heals, no additional treatment will be necessary. Apexogenesis This procedure encourages the root to continue development as the pulp is healed.
This procedure encourages the root to continue development as the pulp is healed. If the tissues are bleeding too apexififation, the MTA will be washed away; this would be an indication that the tissues remaining are still too inflammed to cap.
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, apezogenesis pulp requires proper management according to the degree of inflammation and its vitality.
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.
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 pulp provides a matrix for binding of its cells and provides support allowing communication 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 apexificatiom pulpal tissue vs.
Nonclinical and clinical data will be presented to support the apexogenseis, and outcomes will be presented from clinical studies. In the absence of a vital pulp, dentin deposition is arrested.
If the exposure was carious, or the traumatic exposure crown fracture, exposed pulp is longer apexogenseis 24 hours, then the coronal pulpal tissues are too inflammed to survive a simple capping procedure.
