Outline of Final Research Achievements	Experimental primers containing different chlorophyll derivatives were prepared; bond strength tests and surface observations of tooth were carried out. As a result, a primer containing sodium iron chlorophyllin and 2-hydroxyethyl methacrylate (HEMA) improves adhesion between phosphoric acid-etched dentin and an adhesive resin (4-META/MMA-TBB resin). It was revealed that the optimal concentration of sodium iron chlorophyllin was about 10 times higher than that of sodium copper chlorophyllin and that the effect of improving bond strength was higher for sodium copper chlorophyllin.
