The ability to incorporate iodoform, tetracycline and a combination of iodoform/tetracycline into root canal gutta percha points is described. The iodoform, tetracycline and iodoform/tetracycline combination are bound within the gutta percha points. They act as a reservoir of antimicrobial that is capable of diffusing onto the surface of the gutta percha thereby inhibiting the colonization of bacteria on the gutta percha points and within the root canal system. Tetracycline is capable of coalescing within the dentinal tubules to inhibit long term microbial growth. These medicated gutta percha points are site specific, surface acting antimicrobial gutta percha points.A method of the usage and delivery of amorphous form iodoform gutta percha, iodoform/tetracycline gutta percha, or tetracycline gutta percha within a heated compule with a pressure plunger by delivering the thermo-softened heat labile amorphous form via a pressure extrusion system through a cannula into the prepared root canal system.

The present invention relates to inorganic sterilizing chemicals. The aqueous solution of atomic iodine consists of iodine in 0.5-30 wt%, cosolvent cyclodextrin derivative and water. It is compoundedthrough preparation of ethanol alcohol solution of iodine and saturated water solution of cyclodextrin derivative at 35-70 deg.c, mixing, and diluting with water to the said iodine content.
