Abstract
A phosphorescent endodontic post includes a fiber-reinforced composite material including a polymeric matrix and reinforcing fibers; and phosphorescent particles dispersed within the polymer matrix. The phosphorescent particles are configured to emit visible light for about 5 minutes to about 10 minutes following activation by a standard dental curing lamp operating in the 400 nm-500 nm spectrum. In an embodiment, the phosphorescent particles can include europium-doped strontium aluminate. In an embodiment, phosphorescent particles are uniformly dispersed throughout the polymer matrix.
