Revascularização pulpar em dente anterior traumatizado imaturo

Abstract

Pulp revascularization is an approach to the treatment of teeth with incomplete rhizogenesis and pulp necrosis that allows the continuation of development root canal and resolution of signs and symptoms of pulp necrosis. This report describes the regenerative endodontic approach and 1 year and 9 months follow-up of a maxillary lateral incisor on the left side (tooth 22) of a female patient, 9 years old, treated at a public service for patient care with dentoalveolar trauma. The procedure took place in two sessions: in the first, the root canal was disinfected through in abundant irrigation with sodium hypochlorite (NaOCl) 2.5% followed by intracanal medication based on calcium hydroxide (UltraCal). In the second session, the medication was removed, irrigated with 2.5% NaOCl and ethylene diamine tetraacetic acid (EDTA) 17% with 6 activation cycles with Easy Clean and bleeding was induced to form a blood clot with a K#40 file. Finally, a plug was made with MTA repair followed by a definitive restoration with composite resin. Periapical radiography and computed tomography performed after 1 year and 9 months showed an increase in root length and thickness, in addition to detecting apical closure. There was also an appearance of normality in the periapical region. It was possible to conclude that the reported revascularization protocol is safe and can be successfully used in the public health service in cases of immature permanent teeth traumatized with pulp necrosis, allowing the continuation of root development, with an increase in the length and thickness of the canal wall.
