Revascularização pulpar com plasma rico em plaquetas em dentes com rizogênese incompleta e necrose pulpar: revisão de literatura

Abstract

Pulp revascularization is considered a more conservative alternative for the treatment of permanent teeth with incomplete rhizogenesis and pulp necrosis, in which, through the induction of bleeding in the periapical region, the root canal is filled with a blood clot, in order to induce the formation of a new fabric. However, although the blood clot is a great support, it is poor in growth factors when compared to platelet-rich plasma (PRP), which presents a concentrated suspension of these factors, being considered a promising method in regenerative endodontics. This study aims to evaluate the use of PRP in the technique of pulp revascularization in teeth with incomplete rhizogenesis and pulp necrosis. For this, a literature review was carried out in the PUBMED, LILACS and SCIELO databases, including studies published in English and Portuguese, between the years 2011 and 2021, using the terms regenerative endodontics, platelet-rich plasma and endodontics. It is concluded that revascularization with PRP is a viable treatment, with quick and encouraging results, which promotes the resolution of signs and symptoms, increased thickness of dentinal walls and apical closure.
