Regenerativna endodoncija - mogućnosti i ograničenja

Regenerative endodontics is defined as a “biologically based procedure designed to replace damaged tooth structures, including dentin, root structures, and cells of the pulp-dentine complex”. It is indicated in the treatment of young permanent teeth with pulp necrosis and apical periodontitis, provided that the patient is not allergic to antibiotics used in the therapy and if there is a possibility of restoration of hard dental tissue without the use of posts or intracanal core build-up. The clinical procedure could be divided into two or three sessions and involves thorough rinsing of the root canals, use of antibiotics in the root canal, provoked bleeding from the periapex and covering the blood clot with biological material. The therapy shows a high success rate manifested by the withdrawal of clinical signs of inflammation, healing of the periapical lesion and increased root wall thickness and/or root length. Unlike apexification, the duration of therapy is shorter, the possibility of a root fracture is reduced, and the root canal is filled with the host’s vital tissue.
