Measurement methods for adhesion to dentine: the current status in Japan.
Adhesive test in vitro is performed to evaluate bonding materials. This paper describes methods of measuring adhesion to dentine currently used in Japan, and considers advantages and disadvantages. Various tests are used in Japan. Many factors-dentine substrate, storage conditions, bond strength test method-affect bonding to dentine. Bond strength test methods employed are divided into: tensile bond test and shear bond test. The test method used for the best prediction of clinical performance in bond strength evaluation is discussed. There has also been interest in bonding stability. At present, it may be difficult to propose an optimal standardized measuring method. Standardized experimental conditions in vitro which can simulate conditions in vivo are still under investigation.
