Revascularização pulpar : uma alternativa para o tratamento endodôntico em dentes permanentes imaturos.

Abstract

Traumatic injuries and carious lesions are etiologic factors, which may cause the necrotic pulp of a tooth with incomplete root. As a result, in immature teeth, the development process ceased and the endodontic treatment became necessary and difficult. In such cases, it is hold apexification with calcium hydroxide paste or MTA, to promote apical closure. However, these roots have remained weak and without complementation of the root development. In order to prevent these disadvantages, the pulp revascularization has been institute. The objective of this study was to evaluate, through a literature review, the pulp revascularization technique, to know the cell differentiation mechanism, the newly formed tissue characteristics, indications and advantages of the technique and the protocol for its realization. It can be concluded that pulp revascularization constitute a promising and advantageous alternative therapy for treatment of immature permanent teeth with pulp necrosis and apical periodontitis. Because, through cell proliferation and differentiation, the root walls are strengthening and the root end development occurs.
