Abstract
A bactericidal insert for introduction into a canal in a tooth during a root canal procedure is provided, along with a method of producing the insert and a method of using the insert in a root canal procedure. The insert is in the form of a carrier having a plurality of pores or interstices. The carrier had been impregnated with a liquid photosensitive dye so that the dye entered the pores or interstices and then the carrier with the liquid photosensitive dye forms a dye-impregnated carrier. The dye-impregnated carrier is configured and adapted for insertion within the canal of the tooth. The carrier, if dried, is adapted to receive a wetting agent to dissolve the dye therein to produce a liquefied dye, which is activatable to produce singlet oxygen within the canal when it is irradiated by light from outside of the tooth.
