Fluoride Varnish
A concentrated topical fluoride preparation applied directly to tooth surfaces to prevent caries and reduce dentinal hypersensitivity.
Full Definition
Fluoride varnish is a sticky, resin-based or colophony-based fluoride preparation—typically containing 5% sodium fluoride (22,600 ppm F)—that is painted onto tooth surfaces by a dental professional and allowed to remain in contact with enamel for several hours. It acts as a sustained-release vehicle, delivering fluoride ions that promote remineralisation and inhibit demineralisation of tooth enamel. In the United States, fluoride varnish is also applied by pediatric physicians under preventive health programs. Editors should note that 'fluoride varnish' is always two words and should not be confused with other topical fluoride delivery methods such as fluoride gel or fluoride foam.
Usage
Usage note: Always write as two words: 'fluoride varnish'. Distinguish from fluoride gel (D1206) and fluoride varnish (D1206 or D1208 depending on age) by checking the applicable CDT code in billing documents.
