Abstract
A device for the treatment of periodontal disease includes a handle that has a configuration familiar to dental professionals, and a cartridge, that is locked into the handle when use, typically delivery of a composition to a periodontal pocket is desired. The cartridge provides for effective delivery of compositions, such as agents, as its tip is deformable, typically from a circular to an oval shape so as to flatten. The deformation may be made, either manually, by the dental professional, or upon contact with teeth or other tissues, whereby this flattened tip can penetrate deeply into periodontal pockets for quick and direct application of the composition, for example, therapeutic agents.
