Abstract
Abstract Pharmaceutical compositions for use in densensitizing hypersensitive dentin or eliminating odontalgia comprise N-methacryloyl aminosalicylic acid as an active ingredient and a pharmaceutically acceptable carrier or diluent. The compositions may further include a pharmaceutically acceptable unsaturated compound capable of being copolymerised with the N-methacryloyl aminosalicylic acid and a polymerization initiator.
