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
complete listing of these bodies can be found at www .iso .org/ members .html.

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.

Dentistry — Fluoride varnishes
1 Scope
This document specifies requirements and test methods for total digestible fluoride content and a
minimum soluble fluoride release potential in dental varnishes containing fluoride, intended for use
in the oral cavity directly on the outer surfaces of teeth and fillings. It also specifies packaging and
labelling requirements, including the instructions for use. This document covers fluoride varnishes to
be applied by dental health care workers.
