| Outline of Final Research Achievements |
Microtensile bond strength to the enamel surface irradiated with Er:YAG laser was significantly lower in the two-step self-etch adhesive than in the non-irradiated one, but was significantly higher than that in the one-step self-etch adhesive when irradiated. Although the bond strength to the dentin surface irradiated with Er:YAG laser was almost the same as that of the non-irradiated surface, the two-step self-etch adhesive was significantly higher than the one-step self-etch adhesive. It was not effective to the phosphoric acid pretreatment before applying the one-step self-etch adhesive.
