Regeneração pulpar como alternativa para tratamento endodôntico em dentes permanentes imaturos: revisão de literatura

Abstract

Pulp revascularization can be defined as a differentiation of progenitor cells from the apical portion of young teeth that results in deposition of mineralized tissue in the dentinal walls. Regenerative endodontics uses the concept od tissue engineering to restore the root canals to a healthy state, allowing for continued development of the root and surrounding tissue. It id a promising treatment alternative that promotes both apical closure and root development, and is indicated in teeth with incomplete root formation, as an alternative to apexification a method to induce a calcified barrier in a root with an open apex or the continued apical development of an incompletely formed root in teeth with necrotic pulps. However, the presence of medication for prolonged periods of time can lead to a fragility of the root walls. As a consequence there is a constant search for new alternatives of endodontic treatments that allow full root development. Regeneration has emerged as a new alternatives of endodontic treatment option for young immature teeth with pulp necrosis. To date, there are several reports in the literature of a variety of treatment protocols for revascularization, always seeking to anchive the best way to treatment success. In view of this variety, it is important to study the literature on pulp regeneration, cell differentiation and characteristics of the new tissue formed.
