Conclusiones: La constante actualización del conocimiento, responsabilidad ética del profesional, le permitirá intr oducir los cambios conceptuales y clínicos a la luz de las nuevas evidencias científicas.Abstract: Objective: 1) To assess the clinical performance of 656 cast gold inlay/onlays in a 44-year period; 2) To analyze their indications and distribution regarding the evolution of scientific evidence. Materials and Methods: A total of 656 cast gold inlays/onlays had been placed in 100 patients. Out of 2552 registered patients, 210 fulfilled the inclusion criteria. The statistical representative sample was 136 patients; 140 were randomly selected and 138 were the patients studied. Twelve variables were analyzed. Data processing was done using Epidat 3.1 and SPPS software 13.0. Results: At the clinical examination, 536 (81.7%) were still in function and 120 (18.3%) had failed. According to Kaplan-Meier ’ s method, the estimated mean survival for the whole sample was 77.4% at 39 years and 10 months. Conclusions: Knowledge updating is an ethical responsibility of professionals, which will allow them to introduce conceptual and clinical changes that consider new scientific evidence.
