To obtain a translucent tooth-coating composition for preventing or delaying polluted coloring of teeth by forming coat on the surfaces of teeth and smoothing teeth surfaces while developing whiteness similar to that of diffused reflection of light in a translucent tooth-coating composition for finishing applied after bleaching treatment of natural teeth in dental field.
This translucent tooth-coating composition for teeth for finishing thereof after their bleaching consists mainly of 8-80 wt.% multifunctional acrylate monomer, 16-80 wt.% low boiling point solvent, 0.3-5 wt.% visible light polymerization initiator and 1-20 wt.% titanium dioxide and has 60-95% light transmittance of a cured film. A composition comprising tri or more poly- functional acrylate monomer, a low boiling point solvent which is an acrylate monomer having ≤120°C boiling point, a camphor quinone as visible light polymerization initiator and titanium dioxide having 1 μm size can especially be utilized as the coating composition. Phosphate-based adhesive monomer is preferably further added to the composition.
