History of Flouride Varnish

Fluoride varnish was first introduced in Germany in 1964 under the trade name Duraphat. A similar product (Duraflor) was introduced to United States in 1991. Recently, a third product (CavityShield) has been made available that is packaged in unit-dosages (.25 cc for primary dentition and .40 cc for mixed dentition). Studies done over the past 30 years have exhibited a 25-45 percent reduction in dental caries

In the United States, the FDA has approved fluoride varnish as a "cavity liner" and a desensitizing agent. Its use as a dental caries preventive agent is considered "off label". It is particularly useful for young children with early childhood caries because fluoride ingestion is lower than with gels.
