Abstract

Purpose: To analyze the survival rates and influential factors of in situ root posts from 2007 to 2017, identifying key parameters affecting their longevity. Methods: The study included all restorations treated at the Department of Prosthodontics, Center for Dentistry and Oral Medicine (Carolinum), Goethe-University, from 2007 to 2017, involving 1120 fibre-reinforced root posts with an 8.0% dropout rate and a significance level of alpha <5%. Results: Patients had a mean age of 61.1±14.37 years. The study found a survival rate of 60.71±14.70 years versus a loss at 64.58±10.45 years (p<0.05). The periodontal condition was the most significant factor affecting survival. Cytec Blanco and DT light post showed similar ten-year survival rates of 79.17% and 79.34%, respectively,
without significant differences. Periodontal health was the most critical factor for root post loss. Conclusion: Root post loss is more influenced by patient’s periodontal health and the indication for root canal treatment than by the structural characteristics of the fibre posts. Clinical relevance: This retrospective cohort study addresses the lack of longterm (>10 years) clinical research on fibre-reinforced root posts, focusing on various factors influencing their success or failure.
