Fibers can be used as restorative materials during post-endodontic treatment to avoid tooth fractures. Fibers can modify the stress by initiating a Monoblock effect that aids to dispel the stress along the tooth's long axis. Fibers can also prevent the formation of cracks due to the dispersal of stress to the fibers from the polymer matrix. Glass fiber-reinforced composite is one of the materials that can be used in dentistry for restoration. It is known that enclosing glass fibers into a resin matrix produces glass fiber-reinforced composites. The objective of this study was to evaluate the efficacy of glass fiber-reinforced composite restoration. This study utilized a systematic review that involved searching the literature and selecting articles for review based on the set criteria for exclusion and inclusion. The study established that glass fiberreinforced composite restoration recorded favorable outcomes compared to other non-fiber-reinforced composite materials and other composite materials. Glass fiber-reinforced composite materials are appropriate to be used for restoration based on their clinical efficacy.
