This research proposal is introduced to clinically test short fiber reinforced glass ionomer material from GC Europe due to gap of knowledge present in this area. It is characterized by higher flexural strength compared to resin modified glass ionomer (RMGIC). Additionally, the short fibers provided effective toughening of the RMGIC matrix by a fiber bridging mechanism.
