- - Composition for desensitizer comprising nitrogen doped titania or nitrogen doped titania and antimicrobial

摘要

The present invention relates to a composition for perceptual irritation treatment containing nitrogen-doped titanium dioxide or nitrogen-doped titanium dioxide and an antimicrobial agent and a process for preparing the same, wherein the photocatalytic activity of the nitrogen-doped titanium dioxide by visible light irradiation is determined by It is possible to develop fusion technology in a new area of dental materials by overcoming the existing limitation that the nitrogen-doped titanium dioxide nanoparticles are only active in ultraviolet rays because they promote the antibacterial effect of antibacterial agents such as chlorhexidine and do not show cytotoxicity. And reduce the pain of the patient, as well as prevent secondary diseases caused by dental caries.
