Regenerative endodontics are biologically based procedures designed to replace damaged tooth structures, including dentine and root structures, as well as cells of the pulp-dentine complex. Regenerative endodontic therapy is aimed to regenerate the pulp-dentine complex damaged by infection, trauma or developmental anomaly of immature permanent teeth with necrotic pulp. Potential technologies for Regenerative Endodontic therapy include root canal revascularization, postnatal stem cell therapy, pulp implant, scaffold implant, three dimensional cell printing, injectable scaffold and gene therapy.

The fiber reinforced composite has become an effective material of choice within restorative dentistry. The rationale behind the usage of fiber reinforcement is partly to internally strengthen the structurally compromised tooth and partly to prevent the occurrence of fractures. The efficacy of fiber reinforcement is dependent on several factors, including the resins used, the length of the fibers, the orientation of fibers, the position of the fibers, the adhesion of the fibers to the polymer matrix, and the impregnation of the fibers into the resin. The reinforcing effect of the fiber...
