varnish (vär´nish),

n (cavity liner, cavity varnish), a clear solution of resinous material or natural gum, such as copal or rosin dissolved in acetone, ether, or chloroform, which is capable of hardening without losing its transparency. Varnish is used in cavity preparations to seal out dentinal tubules, reduce microleakage, and insulate the pulp against shock from thermal changes.

varnish, fluoride,

n a sticky yellowish protective coating of 5% sodium fluoride in a resin base that is painted over the teeth to prevent dental caries in children and adults. It hardens on contact with saliva. It is also used to reduce root sensitivity. Its effects on enamel fluoride appear to provide a lower risk of accidental fluoride ingestion than most other topical fluoride treatments.
