Effects of solvent drying time on micro-shear bond strength and mechanical properties of two self-etching adhesive systems.
Dent Mater. 2007 Sep; 23(9): 1114-9 Sadr A, Shimada Y, Tagami J The all-in-one adhesives are simplified forms of two-step self-etching adhesive systems that must be air dried to remove solvent and water before curing. It was investigated whether those two systems perform equally well and if their performance is affected by air-drying of the … Continue reading »
