| Outline of Final Research Achievements |
The aim of this study was to determine the bond durability of self-etch adhesives using shear fatigue strength (SFS) testing that focuses on repeated sub critical loading. Results of the first year study, 3 s or more of phosphoric acid pre-etching prior to application of self-etch adhesive enhances enamel bonding effectiveness not only for the initial bond but also enamel bond durability. The aim of the second year study was to determine the effect of double-layer application of universal adhesives on the bond quality and compare to other adhesive systems. The double application mode is effective in enhancing enamel and dentin bond durability of universal adhesives, but not conventional two-step self-etch adhesives. These results suggest that although the double application mode may enhance the bonding quality of a universal adhesive, it may be counter-productive for two-step self-etch adhesives in clinical use.
