Thermoplastic composition for root canal filling

Abstract

Thermoplastic compositions for cones for filling root canals include guttapercha in association with calcium hydroxide. This association provides the advantages of both guttapercha and calcium hydroxide in cones, simplifying endodontic treatment by preventing a need for dressing or apical tampons. The cones provide a continuous source of calcium hydroxide, regardless of the type of cement used with the cones. Low permeability of the cones ensures that release of calcium hydroxide is slow. Additional ingredients provide rigidity, radio-opacity and coloring. The additional ingredients include zinc oxide, aluminum oxide, barium sulfate, kaolin, and colorant. Methods for making the dental cones are also provided.
