Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 1, Filling and
restorative materials.
This second edition cancels and replaces the first edition (ISO 29022:2013), which has been technically
revised.
The main changes are as follows:
— Types of human extracted teeth for test;
— Concentration range of chloramine-T trihydrate for prepared tooth storage;
— Specification of grit size of final abrasive paper for surface preparation;
— Coefficient of variation in result analysis.

Introduction
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that
compliance with this document may involve the use of a patent concerning testing shear bond strength.
ISO takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has ensured ISO that he/she is willing to negotiate licenses under reasonable
and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the
statement of the holder of this patent right is registered with ISO. Information may be obtained from:
Neil T. Jessop, Ultradent Products, Inc., 505 West 10200 South, South Jordan, Utah 84095-3942, USA.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights other than those identified above. ISO shall not be held responsible for identifying any or all such
patent rights.
The purpose of this International Standard is to establish a simple and easy to use method for documenting a
claim that a material adheres to tooth substance. While the method described in this International Standard
has been used for comparing dental adhesive materials, users of this International Standard should evaluate
usefulness of this method for their particular application(s). There is a variety of other dental adhesion test
methods that may also be suitable or preferable, depending on the objective (e.g. academic research).

Dentistry — Adhesion — Notched-edge shear bond strength
test
1 Scope
This International Standard specifies a shear test method used to determine the adhesive bond strength
between direct dental restorative materials and tooth structure, e.g. dentine or enamel. The method as
described is principally intended for dental adhesives. The method includes substrate selection, storage and
handling of tooth structure, as well as the procedure for testing.
NOTE 1 Testing adhesion to tooth structure is technique sensitive and experience with the test method is required.
NOTE 2 With modification, it may be possible to use this method for adhesive restorative materials (e.g. glass-
ionomer materials).
