Abstract

In dentistry, fiber-reinforced materials present various applications, especially in the restoration of endodontically treated teeth. Among these, short fiber-reinforced composites (SFRC) and polyethylene fibers (PF) are used as substitutes for dentin structure to improve the physical properties of dentin. Objective: to evaluate the efficacy of polyethylene fiber versus short fiber-reinforced composites as dentin replacement materials in endodontically treated teeth (EET). Methodology: A narrative review was performed by searching for articles related to polyethylene fibers and short fiber-reinforced resin composites published between 2013 and 2024. The databases consulted were PubMed-MEDLINE, Google Scholar and Scopus. A total of 34 relevant studies were selected that aligned with the aim of the present article, including in vitro studies, systematic reviews, and narrative literature reviews. Conclusion: The studies reviewed indicate that glass fiber-reinforced resins offer greater fracture resistance, integrity, and clinical longevity than polyethylene fibers. This makes them an effective alternative as a dentin replacement material for endodontic teeth.
