Fiber post: Physics, chemistry, adhesive properties, and its implications on root canal retreatment

Abstract

This chapter covers a comprehensive knowledge about the variety of fiber-reinforced post systems and its implication on the root canal retreatment. When successful outcomes of endodontic treatment are considered, the selection of restorative material becomes a necessity. The objectives of this chapter are to deliver an understanding of chemistry, physics, and adhesive properties of fiber-reinforced posts, including carbon/glass/quartz and prefabricated fiber posts. Although the implications of fiber post on root canal retreatment possess some difficulties, such as post removal, etc.; it is still recommended over other post systems because of their physical and chemical characteristics which include the ideal modulus of elasticity, flexure strength similar to that of dentine; and their ever-evolving adhesive properties. Therefore, it qualifies as a “worthy choice” in endodontic practice when the procedure of retreatment is performed with clinical expertise. Furthermore, advancements in fiber posts system may help prevent the current and the remaining shortcomings.
