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).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on 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 the following URL:

This document was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 7, Oral

care products, in collaboration with the European Committee for Standardization (CEN) Technical

Committee CEN/TC 55, Dentistry, in accordance with the Agreement on technical cooperation between

ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 17730:2014), which has been technically

revised.
The main changes compared to the previous edition are as follows:

— Additional subclause to indicate three samples are tested for total fluoride. Two aliquots are

analysed for each sample.

— A requirement of minimum soluble fluoride release potential and a relevant test method have

been added.

Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction

Fluoride varnishes are used in dentistry primarily for caries prevention and reduction of dentine

hypersensitivity. Fluoride varnishes are applied in the oral cavity directly on the outer surfaces of teeth

and fillings, and are intended to remain at least for several hours.

Specific qualitative and quantitative test methods for demonstrating freedom from unacceptable

biological hazards are not included in this document, but it is recommended that, for the assessment

of possible biological or toxicological hazards, reference should be made to ISO 10993-1 and ISO 7405.
