Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a dental adhesive composition simultaneously solving (1) adhesion to healthy dentin and discolored dentin, (2) discolored dentin color-masking tendency(color hiding) and (3) deactivating effect by photocatalytic activity on bacteria possibly present in discolored dentin sites. SOLUTION: The dental adhesive composition having photocatalytic activity comprises (A) an anatase-type titanium dioxide with a primary particle mean size of 1-500 nm and (B) a polymerizable monomer having intramolecular acidic group. This composition contains 0.1-80 wt.% of the component A based on a total of the components A and B. COPYRIGHT: (C)2006,JPO&NCIPI
