Current Aspects of Regenerative Endodontics: A Systematic Review

Abstract

   Relevance. The modern concept of endodontic treatment in most clinical cases involves extirpation of the pulp with the loss of its plastic, trophic, sensory, and protective functions. In this regard, the search for ways to recreate lost cells and the main substance of the pulp and periodontium to replace the intraradicular space with “vital” tissue. Regenerative endodontics based on the principles of tissue engineering and offers techniques for restoring damaged tissues of the pulp-dentin complex based on the use of stem cells, growth factors, and an organic matrix.   Aim. Systematize information presented in scientific articles about research conducted, opportunities and development prospects in the field of regenerative endodontics.   Materials and methods. A search of literature sources was carried out in the PubMed, dissercat.com, elibrary database.ru, cyberleninka.ru, by keywords, “regenerative endodontics”, “stem cells”, “growth factors”, “pulp-dentin complex” with a choice of article types “Clinical Trial”, “Meta-Analysis”, “Review”, "Systematic Review".   Results. After analyzing the literature review, an idea was obtained about the current stage of development of regenerative endodontics, preclinical and clinical studies on the restoration of the pulp-dentin complex. Clinical cases based on the triad of regenerative endodontics are presented, as well as an algorithm for performing these therapeutic procedures.   Conclusions. Regenerative endodontics is a rapidly developing discipline whose clinical advances are primarily related to the treatment of immature tooth roots, which results in continued root development. Subsequent scientific research is aimed at obtaining significant results in the treatment of a fully formed permanent tooth, which will ensure a unique restoration of the immunological, sensory and protective properties of the pulp-dentine complex.
