Abstract: A composition for treating periodontal disease by means of a therapeutic agent delivery device placed within the periodontal pocket so that release of the therapeutic agents occurs in the immediate vicinity of the disease process, without that a release adjusting agent or adhesive agent is present so that biocompatibility or allergic problems cannot arise. The composition comprises a therapeutic agent in a biocompatible polymeric material. The therapeutic agent is soluble both in water and in alcohol and the biocompatible polymeric material is a liquid methacrylate copolymer such as EUDRAGIT® RL, EUDRAGIT® RS or a mixture thereof. The polymers are provided as a liquid in an alcoholic solution, (preferably about 96%), or hydro-alcoholic solution (preferably 20:80 w/w). When the polymer is spread on a surface, the alcohol evaporates and the polymer forms a polymeric film on that surface. When water present in the mouth tissues permeates through the material, the therapeutic agent is released.

Abstract: A dental composition for the treatment of dentinal hypersensitivity and in particular for the desensitization of exposed dentin, the desensitizing treatment of deep cavities, the desensitizing treatment when replacing dental layers, the stumps desensitizing treatment before placing dental prosthesis. The composition can be used as a solution or as a gel. In the first case two distinct liquid solutions for use successively on the exposed dentin are provided for. In the second case two distinct gel compounds spread successively on the exposed dentin are provided for. The first solution or the first gel compound comprises preferably three soluble potassium salts, whereas the second solution or the second gel compound comprises a calcium salt and a soluble strontium salt.
