1. A method for treating decay of a tooth by promoting regeneration of vascularized dental pulp in a root canal in the tooth, the method comprising:
positioning a fiber in the root canal of the tooth;
filling at least a portion of the root canal with an unset hydrogel composition, such that the unset hydrogel composition contacts at least a portion of the fiber;
setting the hydrogel composition, thereby forming a set hydrogel; and
removing the fiber from the set hydrogel, thereby leaving a channel in the set hydrogel, the channel being sized to form a vascular-like conduit.
