Cirurgia parendodôntica com retro-obturação utilizando cimento biocerâmico PBS HP Cimmo®: análise por tomografia computadorizada de feixe cônico de um caso clínico

Abstract

Paraendodontic surgery is classified as the last therapeutic resource aimed at solving the problems created or unresolved by endodontic treatment. With regard to retro-filling materials used in this surgical modality, silver amalgam has been replaced by intermediate restorative material (IRM®), Super EBA® cement (reinforced zinc oxide and eugenol cement) and Mineral Trioxide Aggregate (MTA), the latter of which has a high success rate. The aim of this study was to evaluate tomographically in a clinical case, the effect of a bioceramic cement recently launched on the dental market, PBS HP Cimmo® - Pozzolana Biológico Silva Hight Plasticity (MJS Indústria e Comércio de Materials para Saúde Ltda., Pouso Alegre, MG. Brazil) and its influence on the remission of periapical lesions after endodontic surgeries. A 45-year-old male patient, J.M.M., came to the Maxillofacial Surgery clinic at the School of Dentistry of the Federal University of Juiz de Fora and a radiographic examination revealed an extensive and refractory periapical lesion that made endodontic treatment and retreatment impossible for the teeth involved. Surgery was carried out on the patient using an incision, detachment, curettage, apicoectomy, retropreparation and retrofilling with the cement described. Follow-up analysis was performed using cone beam computed tomography (CBCT) and showed a considerable reduction in the lesion and a change in bone density. It is concluded that bone tissue was formed in the region during the clinical periods studied, with clinical improvement and regression of the periapical lesion.
