The revitalisation (revascularisation) of necrotic pulp
Aparadigm shift has taken place in the last few years concerning the treatment of teeth whose root-canal system is still growing, particularly in the case of dead or dying pulp and periapical periodontitis (an acute or chronic inflammatory lesion around the apex of a tooth root which is caused by bacterial invasion of the pulp of the tooth).
Classical treatment was aimed at the so-called apexification, which required the creation of a barrier around an opening into the root-canal system, which allowed it to be filled in a controlled manner. However, growing teeth are subject to a higher risk of fracture, due to their fragility.
Completely new biological thinking and technology underlies regenerative endodontics. Its aim is to allow new tissue to be created inside the root-canal system by bringing together multi-potent postnatal stem cells from the dental papilla, growth factors from dentin, and platelet-enriched plasma into a matrix.
Crucially this process enables the root to further develop, retaining its structural integrity as it does so. The tooth continues to grow longer and thicker, and this increases chances of long term vitality.
