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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In exceptional circumstances, when a technical committee has collected data of a different kind from that which
is normally published as an International Standard (“state of the art”, for example), it may decide by a simple
majority vote of its participating members to publish a Technical Report. A Technical Report is entirely
informative in nature and does not have to be reviewed until the data it provides are considered to be no longer
valid or useful.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TR14569-1 was prepared by Technical Committee ISO/TC106, Dentistry, Subcommittee SC2,
Prosthodontic materials.
This first edition cancels and replaces ISO/TS 14569-1:1999, which has been technically revised.
ISO/TR 14569 consists of the following parts, under the general title Dental materials — Guidance on testing of

Introduction
It is well understood that the wear mechanisms in the mouth are very complex. In addition they may differ from
one individual to another. Therefore it appears impossible to reproduce these varying conditions in a single
wear test.
As a consequence, many wear tests have been proposed in dental science. Most of them consider mainly one
specific aspect of the different mechanisms, and some of them even claim to be able to characterize the wear
resistance of dental materials completely. However, these procedures are not really comparable because of the
different wear mechanisms considered, and the lack of a generally accepted test method.
It therefore makes sense to utilize laboratory tests, investigating the various wear aspects arising separately
under clinical conditions. They may determine wear, only for the clinical situation in which the same wear
mechanism dominates; but it might be possible to predict the complete clinical wear by a number of different test
methods.
In this part of ISO/TR 14569, wear by tooth brushing is considered. This is one aspect of the wear problem and
may only be important for materials exposed to tooth brushing, such as materials used on labial surfaces.
The intention of this part of ISO/TR 14569 is to define conditions for the various existing laboratory tests so that
they can deliver comparable results and can be used for at least a screening of different materials.

Dental materials — Guidance on testing of wear —
Part 1:
Wear by toothbrushing
1Scope
This part of ISO/TR 14569 provides guidelines for test methods for the assessment of resistance to wear by
tooth brushing for the following materials:
— materials used for the preparation of artificial teeth;
— veneering of crowns and bridges.
This part of ISO/TR 14569 does not cover phenomena such as the marginal degradation and loss of substance
by chemical processes, swelling, splintering of edges or wear from contact with the antagonist.
