摘要

@@Early-generation dentin adhesives are relative hydrophobic and usually cannot penetrate through the demineralized dentin layer. The development of the wet bonding technique [1] has led to higher bond strength by preventing the collapse of demineralized dentin and enhancing the infiltration of adhesive into collagen networks. This requires the adhesives to be hydrophilic enough to wet the dentin and to be more moisture resistant. These adhesives usually use the total-etch technique which involves separate acid etching and rinsing steps. The contemporary selfetching adhesives/primers were designed to combine both the etching function and the resin-forming function, thus eliminating rinsing steps. Compared to total-etch adhesives, self-etching adhesives are generally more user-friendly, less technique sensitive and easer in achieving a hermetic seal. For both type adhesives, water play an very important role in their bonding processes. Water can prevent hydrophobic components in adhesive to penetrate into wet demineralized dentin, water can cause phase separation when the adhesive with hydrophobic components are applied on the dentin, water also has obvious effect on the double bond degree conversion of the adhesives in the visible light polymerization process.
