FIELD: chemistry.

SUBSTANCE: group of inventions relates to compositions of materials, containing basic aminoacid arginine, and their application for coating devices intended for application in the oral cavity, or for manufacturing such devices. One of composition versions contains basic amino acid arginine, in free form or in form of salt, placed in biodegradable polymer, selected from polyacrylates, polymethacrylates or their copolymers. The other composition version contains matrix with pores from 10 to 70 mcm and basic amino acid arginine, located inside said pores, with matrix representing plastic, selected from polyethylene, polymethylmethacrylate, polyurethane, polyethylene terephthalate, polypropylene, polystyrene, polyamides, bioplastic. Also claimed is application of said compositions of material in production of device for application in the oral cavity, as well as device for application in the oral cavity (for instance, toothbrush, tongue scraper, mouthguard, orthodontic correcting device), which has a surface coated with any of said compositions, and methods of delivery of basic amino acid arginine by means of such device into the oral cavity of a subject, requiring it.

EFFECT: application of such devices, manufactured with application of said compositions, ensures release of arginine into the oral cavity within a long period of time.
