Abstract
A polymeric controlled delivery system is provided for use in treating periodontal disease. The delivery system in a variety of forms is placed directly in the infected gingival tissue where the chemotherapeutic agent is slowly released into the tissue and into the infected periodontal pocket by means of the gingival crevicular fluid originating in the gingival tissue.
