Abstract
Therapeutic agent delivery devices and methods for using them in treatment of dental disease are disclosed. In the treatment of periodontal disease, a therapeutic agent such as tetracycline mixed in a polymeric matrix such as ethylene vinyl acetate copolymer is packed into the area to be treated and kept in place for a suitable time, during which the therapeutic agent diffuses out of the polymeric matrix, providing continuous therapy for the treatment site.
