Layonel Pereira da Silva, Priscilla Bispo de Carvalho Barbosa, Jéssica da Silva, Rita de Cássia de Souza

Root resorption is a condition characterized by demineralization of the dental tissue, which may be due to a physiological or pathological process. The physiological process is manifested by the natural exfoliation of primary teeth, however, the pathological is linked to the loss of mineralized structure in permanent teeth, in order to manifest itself as a result of several etiological factors, among them dental trauma and orthodontic movements. The aim of this study was to present, through a case report, the applicability and effectiveness of Bio-ceramic cements, in the face of the diagnosis of External Inflammatory Root Resorption (RRIE) with pulp necrosis. The dynamics of treatment associated the disinfection process of the root canal system using Sodium Hypochlorite (NaClO) at 2.5% as irrigant and Ca(OH)₂ as intracanal medication, with root canal filling with Bio-ceramic cement PBS HP CIMMO®. During clinical and radiographic follow-up and after completion of the case, regression of the fistula, absence of painful symptoms, and root neoformation were observed. It was concluded that the Bio-ceramic cements were effective in the treatment of the presented pathology, guaranteeing its safe use.
