Abordagem clínico-cirúrgica de paciente com raquitismo hipofosfatêmico familiar: relato de caso

Abstract

Familial hypophosphatemic rickets (RHF) is a condition generally transmitted as an X-linked dominant characteristic, resulting from the mutation of the phosphate regulator gene with homologies for endopeptidases on the X chromosome (PHEX), expressed predominantly in osteoblasts and odontoblasts, affecting bone remodeling. Oral manifestations, such as the formation of multiple dental abscesses, are common in these patients. The aim of this study was to report the treatment of a periapical cyst associated with dental element 11 with post-trauma root fracture in a 17-year-old male patient with RHF, who attended the Integrated Clinic of the Federal University of Ceará with complaint of tooth mobility. Paraendodontic surgery associated with the use of fibrin membrane rich in platelets and leukocytes (FRP-L) was performed to promote local bone repair. The present clinical case is followed up for 10 months.
