BORGIA BOTTO, Ernesto; BARON, Rosario  and  BORGIA, José L. Cast posts: a forty-four year retrospective clinical study in a specialized private practice. Odontoestomatología [online]. 2015, vol.17, n.25, pp.11-22. ISSN 0797-0374.

Abstract Aim. The aim of this study was to examine the longitudinal clinical result of the use of cast posts and cores and crown restorations in endodontically treated teeth over a 44-year period. Materials and methods. Out of 130 randomly selected patients, 95 had had 297 teeth rehabilitated with cast posts and cores and crown restorations. The endodontic rehabilitation was considered successful when the tooth remained functional with no clinical or radiographic pathology. Results. The success rate was 90% (268) and the failure rate 10% (29). Cohen’s Kappa index ranged between 0.78 and 1. Conclusions. In this 44-year retrospective study, the clinical success rate was 90%. The mean survival time of the studied teeth was 19 years. The failure rate was 10%; tooth fractures were the most prevalent failures (5% of all restored teeth).
