Revascularização do tecido pulpar: uma revisão de literatura.

Abstract

Teeth with incomplete rhizogenesis and necrotic pulp present adversities to endodontic treatment, mainly due to fragile root walls and open dental apex. The standard treatment in these cases is apicification, but this technique does not allow the increase of wall thickness nor root maturation, and due to successive changes of intracanal medication are more subject to fracture. With this, pulp regeneration appears as a promising alternative. This technique proposes root canal disinfection with minimal instrumentation and abundant irrigation, followed by periapical region bleed stimulation. The formation of the clot, which fills the interior of the root canal, stimulates the development of a new tissue inside, thus promoting the end of root development. The aim of this study was to perform a literature review on pulp revascularization as an alternative to conventional treatment in teeth with incomplete rhizogenesis and necrotic pulp. A literature review was conducted with research on the following databases: Latin American and Caribbean Health Sciences Literature (LILACS), ScientificElectronic Library Online Electronic Library (SciELO), PubMed, VHL - Virtual Health Library and books, published in English and Portuguese, for the period 2001-2019. Exclusion criteria were articles that did not address the issue in question and did not have within the established restriction period. In the present study, the effectiveness of the pulp revascularization technique was observed, but there were divergences in the protocols used, especially regarding the irrigating solution and intracanal medication. Thus, it is concluded that this treatment is feasible in cases of incomplete rhizogenesis, but further studies are needed to standardize a protocol for the analysis of satisfactory long-term clinical results.
