Abstract
Objective: This randomized controlled trial compared the 15-year clinical success and survival rate of endodontically treated teeth restored with glass-fiber or metal posts.
Methods: 131 patients in need of 182 post and single-crown restorations were included. Teeth were randomly assigned to the control group (metal post, Parapost XT, Coltène) or test group (glass-fiber post). Teeth in the test group were further divided based on the size and shape of the root canal (RC). Teeth with a small RC were restored with prefabricated glass-fiber posts (Parapost Fiberlux, Coltène) and teeth with a wide oval canal with custom-made glass-fiber posts (Everstick, StickTech). Patients had follow-up appointments at 3, 5 and 15 years. Success (original post present) and survival (present after intervention) probability lifetime curves, corrected for clustering, were calculated (Kaplan-Meier).
Results: The mean follow-up time was 179.6±7 months, and the recall rate was 91.6%. Success rate was 48.0% for metal posts, 59.2% for prefabricated glass-fiber posts and 49.5% for custom glass-fiber posts. Survival rate was 53.6% for metal posts, 68.5% for prefab glass-fiber posts and 55.3% for custom glass-fiber posts. No statistically significant effect of post material was observed. There was, however, a trend towards better success/survival for teeth with prefabricated glass-fiber posts. Teeth with metal posts failed more frequently due to root fracture than teeth with glass-fiber posts.
Conclusions: There was a trend towards better clinical success and survival rate for teeth restored with glass-fiber posts, even though post material had no statistically significant effect on the clinical outcome.
Clinical significance: After 15-years, teeth restored with glass-fiber posts tended towards better clinical success and survival than teeth restored with gold-alloy posts. The difference in clinical outcome was, however, not statistically significant, probably due to a low effect size of the post material on success and survival.
期刊介绍：
The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis.
Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research.
The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
