Self-etching dentin bonding systems are attractive in that removal of the smear layer and smear plug is not required. It was suggested that less aggressive versions of self-etching primers failed to etch through clinically relevant thick smear layers, resulting in decrease in tensile bond strength. On the other hand, self-etching dentin bonding systems are claimed to be able to etch and prime s...

STATEMENT OF PROBLEM The optimal luting material for fiber-reinforced posts to ensure the longevity of foundation restorations remains undetermined. PURPOSE The purpose of this study was to evaluate the suitability of 3 dual-polymerizing resin cements and 2 dual-polymerizing foundation composite resins for luting fiber-reinforced posts by assessing their Knoop hardness number. MATERIAL AND ...

In dynamic force spectroscopy, a (bio-)molecular complex is subjected to a steadily increasing force until the chemical bond breaks. Repeating the same experiment many times results in a broad distribution of rupture forces, whose quantitative interpretation represents a formidable theoretical challenge. In this study we address the situation that more than a single molecular bond is involved i...
