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. Published by Elsevier Inc. In addition to immune cells, the dental pulp contains odontoblasts, which are specialized cells capable aoexogenesis producing dentin.
In turn, the walls of the root canal will thicken, and the tooth will become stronger.
APEXOGENESIS / APEXIFICATION – Drexel Hill, PA Endodontist
If the pulp heals, no additional treatment will be necessary. If the pulp is irreversibly inflamed or necrotic, root-end closure procedures are required when the apex has not fully formed.
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. Drexel Hill, PA The MTA is sealed with a leak-proof restoration glass ionomer, for example and the zpexification is recalled at appropriate intervals to re-evaluate healing and continued root development.
In the absence of a vital pulp, dentin deposition is arrested. The more mature the root becomes, the better the chance for the survival of the tooth. 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. 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.
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. When an immature tooth is affected by caries or trauma, the pulp requires proper management according to the degree of inflammation and its vitality. Nonclinical and apecogenesis data will be presented to support the recommendations, and outcomes will be presented from clinical studies.
Apexification & apexogenesis.
In this case, the unhealthy 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.
The pulp provides a matrix for binding of its cells and provides support allowing communication between the cells. The coronal portion of the canal space is then acid-etched, and a bonded apexificarion or galss ionomer is condensed into the canal to re-enforce the root and provide more sturctural integrity.
Maintenance of pulp vitality will allow continued root development along the entire root length. 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. If the exposure is non-carious mechanical and root development is incomplete, then a true pulp capping can be attempted.
