Cambios dimensionales en cementos a base de resina epoxica y biocerámico, en paciente con tratamientos de conductos primarios del posgrado de endodoncia de la Universidad Católica Santiago de Guayaquil durante el 2023- 2024 : estudio comparativo, longitudinal y retrospectivo.

Abstract

Problem: In recent years, endodontic sealers have incorporated new developments, introducing materials designed to improve biocompatibility and adhesion, such as bioceramic cements and epoxy resin-based sealers. Objective: To evaluate, through a retrospective approach using radiographic images, the dimensional changes of endodontic sealers over a one-year period, in order to determine whether these changes alter the quality of root canal sealing and the longterm periapical condition. Methodology: This study followed a quantitative, observational, longitudinal, and retrospective design. The sample consisted of 80 treated teeth, of which 40 were obturated with epoxy resin-based sealer (Ah Plus) and the remaining 40 with bioceramic sealer (Neosealer Flo). Results: Radiographic assessment indicated the presence of sealers in 91.3% of cases, while 8.8% showed absence, suggesting very low dimensional changes. Apical healing was also observed radiographically after one year, with reduction in lesions according to the PAI. These findings describe sealer stability over one year, with no conclusive superiority between the evaluated materials.
