New development of adhesion theory

Abstract

In this study, on conventional dentine adhesive tests, first the morphology of test sample was classified, secondly fracture strength and failure mode were defined, and third the effect of adhesive strength was clarified. As a result, a new micro test was proposed. In using cylindrical sample or micro shear test sample, the value obtained was not shear strength, and also an apparent one. Thus, in this study, the new micro shear test proposed first by the authors gives a real adhesive shear strength.
