Dentistry - Testing of adhesion to tooth structure
1 Scope
This document specifies two bond strength measurements tests (tensile and shear), test for measurement of marginal gaps around fillings, a microleakage test, and some specific test methods for bond strength measurements.
This document gives guidance on substrate selection, storage, and handling as well as different test methods for quality testing of the adhesive bond between dental restorative materials and tooth structure, i.e. enamel and dentin.
This document does not include requirements for adhesive materials and their performance.

For the purposes of this document, the terms and definitions given in GB/T 9937 and the following apply.
3.1
adhere
to be in a state of adherence

adhesion
state in which two surfaces are held together by chemical or physical forces, or both, with the aid of an adhesive (3.5)
3.5
adhesive
substance capable of holding materials together
