Abstract
Regenerative endodontics has become a revolutionizing tissue engineering concept in the treatment of immature permanent teeth for over two decades. It has been described as a ‘paradigm shift’ in the treatment of immature teeth, since it fosters continued root maturation. An immature necrotic permanent tooth is usually a result of trauma or infection due to which the tooth becomes non-vital before completing root development. In such cases, the root walls are left thin and weak with an open apex. Traditional apexification procedures may resolve pathology but have not been able to prove tooth survival due to absence of continued root development and risk of root fracture. A successful regenerative endodontic procedure (REP) results in resolution of signs and symptoms of pathology, radiographic signs of healing, proof of continued root development as well as presence of pulp vitality due to the regeneration of pulp tissue in the root canal. Various stem cells, growth factors, scaffolds and suitable environment form the tetrad of elements necessary to induce regeneration of dental pulp. While there has been some success in isolating dental pulp cells with in-vitroexperiments, it has been proven to be rather difficultto implement the same in a practical perspective ex vivo. Although there has been clinical success related to REP, histologically they seem to undergo guided endodontic repair rather than true regeneration of physiologic pulp tissue. This review provides an overview of components of tissue engineering, clinical protocol and predictable outcomes for REP and recent advances in regenerative dentistry.
