Enhancing mechanical properties of glass-ionomer cement with hemp fiber: a sustainable approach for dental restorations

Abstract Background: A novel approach to enhancing the mechanical properties of glass-ionomer cement (GIC) may incorporate natural fiber. This study aims to evaluate the effects of raw and pure hemp fiber additions on the flexural strength (FS) and surface roughness (SR) properties of glass-ionomer cement (GIC). Methods: Hemp fibers sourced from the local population were harvested, dried, and separated, then prepared in raw and pure forms to assess their impact on the FS and surface roughness of GIC. Synthesized GICs
