Abstract
The present invention provides a dentinal tubule occlusion material excellent in terms of initial degree of dentinal tubule occlusion, resistance of dentinal tubule occlusion to acids, handling properties, and storage stability. The present invention relates to an one-pack type dentinal tubule occlusion material comprising fluorapatite particles (A) having an average particle diameter of 0.6 to 10 μm, inorganic particles (B) having an average particle diameter of 0.6 to 10 μm and reactive with water to form apatite, and a non-aqueous dispersant (C).
