摘要：

Three variables associated with adhesion testing were examined: (1) the test mode, shear and tension; (2) design of the tensile apparatus; and (3) tooth substrate, human and bovine. Findings revealed no significant differences in bond strength by one tensile test and a shear test. However, the shear test produced more true adhesive failures; thus it may be preferable to use a shear test for adhesion testing. Bond strengths with some adhesive systems differed significantly when tested by two different tensile apparatus. Design of the test apparatus appeared to affect values. Bond strength measurements obtained with human and bovine enamel were essentially comparable. Values with dentin varied. There appeared to be a trend for higher bond strength values with bovine than with human dentin.
