Abstract

The purpose of the present invention is to provide a sole component that can exhibit a function as an oral composition, such as the prevention of dentinal caries, the prevention or amelioration of dentin hypersensitivity, the inhibition of the formation of stains, the removal of stains or the like, or a combination of two or more of such components. The present invention provides an oral composition containing a component (A) which is a compound having at least one lactam skeleton selected from the group consisting of a gamma-lactam skeleton, a delta-lactam skeleton and an epsilon-lactam skeleton and also having an acidic group and/or a salt of the compound.

Description

technical field [0001] The present invention relates to a composition for oral cavity. Background technique [0002] The gums in the oral cavity tend to shrink due to periodontal disease or aging of the body. If the gums recede, the roots (roots) of the teeth that were not exposed become exposed. The root of the tooth exists in the state where the dentin is not covered by the enamel. Because dentin has numerous small tubule structures, it also contains more organic matter layers mainly composed of collagen, so its mineral density is low, about 50%, which is about 97% of that of enamel. In comparison, it is physically and chemically fragile. Therefore, if the root of the tooth is exposed in the oral cavity due to receding gums, caries (dentine caries) is prone to occur. Such dentin caries of the tooth root starting from exposure of the tooth root is called root surface caries. [0003] The pathogenesis of dentin caries (root caries) is as follows: First, plaque is attach...
