Adhesive Cementation of Glass-Fiber Posts: A Narrative Review of Materials and Techniques

This review aims to synthesize current evidence-based protocols to guide clinicians toward predictable and durable adhesive cementation of glass-fiber posts in intraradicular dentin. Endodontically treated teeth (ETTs) frequently exhibit significant structural loss, requiring additional retention strategies, such as glass-fiber posts bonded with resin cements. Clinical outcomes depend on multiple factors, including adequate dentin substrate preparation, appropriate adhesive strategies, and precise cementation techniques. The presence of smear layer debris may compromise adhesion; therefore, effective cleaning protocols are essential to ensure a contaminant-free substrate. Surface treatments of glass-fiber posts may enhance chemical bonding by exposing glass fibers and improving silane coupling. The selection of resin cement systems must consider limitations related to light transmission, polymerization depth, and the adhesive strategy employed. Moisture control and proper solvent volatilization are critical to optimizing bond strength, as is the prevention of contamination during cement application. Techniques that minimize porosity improve cement homogeneity and reduce interfacial defects that may act as failure initiation sites. Furthermore, the choice of core build-up material plays an important role in restoration durability. Collectively, these considerations demonstrate the importance of material selection and clinical technique in achieving reliable adhesive cementation of glass-fiber posts.
