Описание (английский):

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.

Overview

ISO 17730:2020 - Dentistry - Fluoride varnishes specifies requirements and test methods for fluoride-containing dental varnishes intended for topical application to the outer surfaces of teeth and fillings by dental health care workers. The standard defines how to measure total digestible fluoride content, sets a minimum soluble fluoride release potential, and establishes packaging, labelling and instructions for use. It is intended to support consistent product quality, lab testing and regulatory compliance for fluoride varnish manufacturers and testing laboratories.

Key topics and technical requirements

Total fluoride content

Measured using extraction and analysis by a fluoride ion-selective electrode (F-ISE) in accordance with ISO 19448 methods.
The declared fluoride content on the package shall not deviate by more than ±20% when tested per the standard.
Sampling: tests are performed on retail-packaged material from the same batch; three samples are prepared and each sample yields two aliquots (six analyses total).

Fluoride release potential

A minimum soluble fluoride release potential is required: ≥ 14.2 ng F/mm, determined by the test method given in Annex A (or by an equivalent validated method of similar sensitivity and accuracy).

Test conditions and procedures

Standard test temperature: 23 °C ± 2 °C.
Key reagents and apparatus referenced: TISAB buffer (and 50% diluted TISAB), chloroform extraction, KOH treatment if fluorosilane is present, F-ISE/reference electrode, calibrated pipettes and balances.
Detailed sample preparation, extraction, calibration and calculation steps are prescribed to derive fluoride concentration expressed as mg/g and mass percent.

Packaging and labelling

Requires clear instructions for use and appropriate outermost packaging for products intended for application by dental professionals.

Applications and who uses this standard

Manufacturers of fluoride varnish for product development, quality control and labelling compliance.

Analytical laboratories performing routine testing or batch release testing for total fluoride and release potential.

Regulatory affairs teams and notified bodies evaluating product claims and safety/performance documentation.

Dental professional organizations and procurement specialists assessing product specifications.

Indirectly useful for researchers studying fluoride delivery systems, though the standard notes that quantitative release testing does not directly link to clinical outcomes.
