A biocompatible decellularized pulp scaffold for regenerative endodontics. Chogle Pages 677-689 J.S. That is the hope offered by regenerative endodontics, an emerging field focused on replacing traumatized and diseased pulp with functional pulp tissue. However, there is no regenerative therapy for most endodontic diseases. A biocompatible decellularized pulp scaffold for regenerative endodontics M. Matoug-Elwerfelli1, M. S. Duggal2, H. Nazzal3, ... scanning electron microscope and DNA quantification assay. A study showed that regenerative endodontic procedures had better clinical outcomes as compared to apexification procedures, both with MTA and calcium hydroxide such as in aspects of absence of pain, swelling and sinus tracts. Regenerative Endodontics and Tissue Engineering: What the Future Holds? 1517-1525. A review of regenerative endodontics: current protocols and future directions. The idea that one can replace damaged structures and regain functionality (such as nociception and immune competency) in previously necrotic and infected root canal systems has been groundbreaking. Clinical success is resultant from the reestablishment of blood supply to the ischemic but uninfected dental pulp tissue. [44] This indicates that a space that was previously vacant (debrided root canal) may become populated with an innervated tissue supported by vascularity. The principles of regenerative medicine can be applied to end-odontic tissue engineering. Serving as a Director for the IADT would be an exciting opportunity to broaden my horizons and give back to the dental community through my service in the field of traumatology. The presence of dens evaginatus or dens invaginatus were the second most common etiology of pulp necrosis in immature teeth. It has been proven that the vitality of dental pulp in immature teeth is preserved and it is free of signs and symptoms of disease even though it has sustained traumatic injuries such as avulsion and intrusion. Therefore, the selection of irrigants as well as their sequence may play essential roles in conditioning dentin into a surface capable of supporting differentiation of a desired cell phenotype. Contemporary regenerative endodontic procedures involve at least 2 appointments. Besides, MTA is used as the coronal barrier on the blood clot due to its biocompatibility, and its ability to promote cell differentiation and hard tissue production without adverse tissue reactions. Goldberg M, Six N, Chausssain C, DenBesten P, Veis A, Poliard A. Dentin extracellular matrix molecules implanted into exposed pulps generate reparative dentin: a novel strategy in regenerative dentistry. Both vital and non vital pulp therapies should be taken into consideration to keep the natural teeth as long as possible. Hence, contemporary regenerative endodontics originates from the trauma literature and embarks into the field of tissue engineering. Journal of Endodontics, Volume 44, Issue 10, 2018, pp. Thus, the primary therapeutic goal of regenerative endodontic procedures is to promote the healing, survival and function of the tooth. We agreed that there has been little point in investing effort in growing yet every other encyclopaedic, in … Regenerative Endodontics; Additional Clinical Resources. select article Regenerative Endodontics and Tissue Engineering: What the Future Holds? Histology wise,[8][9] ingrowth of connective tissue into the canal space was observed. Conventional root canal therapy cleans and fills the pulp chamber with biologically inert material after destruction of the pulp due to dental caries, congenital deformity or trauma. Hence, the asymptomatic tooth is proceeded to the next step of regenerative endodontic treatment. Regenerative protocols and immature teeth. His analysis of dental remains has provided information about America’s early settlers and helped solve mysteries about America’s first serial killer. [47], However, pulpal necrosis in immature teeth often results in incomplete root development. Chand V. CU, Joseph SVG, George J, John MK, Anand S, NaiR MG that periapical healing could be stimulated with the help of a blood clot inside the root canal. Then, an absorbable collagen barrier is placed above the blood clot followed with MTA and glass ionomer cement. The expansion of the field of regenerative endodontics was also dependent on the contributions from important studies in dental trauma. Odontoblasts[10] were required to aid in pulpal healing but these cells were lacking in this pioneer study. Dr. Anibal Diogenes is the principal investigator of a clinical trial evaluating the clinical outcomes of stem-cell based root canal therapies in … The use of postnatal autologous stem cells, especially the mesenchymal stem cells is optimal in regenerative endodontic applications. During the first visit, after local anesthesia injection; isolation of the tooth is done with a rubber dam, and access is performed with a cutting instrument, which is a round bur to remove the dead pulp. [51] In order to promote pulp regeneration in infected root canals, greater efficiency of disinfection is required. These mesenchymal stem cells are found in dental pulp [20][21] (DPSCs), the apical papilla [22][23](SCAP) and even in the inflamed periapical tissue [24] (iPAPCs) collected during endodontic surgical procedures. J Istanb Univ Fac Dent 2017;51(3 Suppl 1):S41-S51. On the contrary, if the dentin cylinders are irrigated with 17% EDTA either alone, or following NaOCl treatment, a dentin surface that promotes cell differentiation into cells expressing an appropriate marker for a mineralizing phenotype, such as the dentin sialoprotein is produced. Volume 56, Issue 2 April 2012. Long term calcium hydroxide treatment[4] or placement of mineral trioxide aggregate (MTA)[3] apical plug was performed. Purchase Regenerative Endodontics, An Issue of Dental Clinics, Volume 56-3 - 1st Edition. Tetraclean 4. Regenerative endodontics 1. Therefore, complete cleaning and shaping as well as obturation of these teeth are difficult or sometimes impossible, due to high risk of fracture during the procedure [48], Regenerative endodontics has 3 critical steps: adequate disinfection of the root canal system, induction of bleeding through overinstrumentation to create a scaffold for stem cells, and coronal sealing of the blood clot with a biocompatible material, such as MTA, The procedure is applied in two visits as follows:[49]. Albuquerque MT, Valera MC, Nakashima M, Nör JE, Bottino MC (2014) Tissue-engineering-based strategies for regenerative endodontics. Learn More. Ongoing research has evaluated combinations of stem cells, growth factors, and scaffolds that result in histological regeneration of pulp tissues.
