PROBLEM TO BE SOLVED: To provide a dental adhesive composition capable of simultaneously solving the following requirements (1) to (3). (1) Adhesion to healthy and colored / discolored tooth, (2) Shielding property against colored or discolored tooth color (color hiding), and (3) inactivation by photocatalytic action on bacteria that may be present in the colored part. A) Anatase type titanium dioxide having an average primary particle size in the range of 1 to 500 nm, (B) a polymerizable monomer having an acidic group in the molecule, and the anatase type dioxide. Dental adhesive composition having photocatalytic action, containing titanium (A) in an amount of 0.1 to 80% by weight based on the sum of the components (A) and (B) [Selection] None |
