 # Application of fluoride varnish after luting a crown has which of the following beneficial action?
A. Removes fluorides from enamel
B. Reduces the peripheral seal
C. Provides desensitizing action
D. Allows dissolution of marginal cement


The correct answer is C. Provides desensitizing action.

Fluoride applied after crown cementation has the benefit of reducing the decalcification in the area and helps to seal the tubules which may be open at the cervical tooth margin. This provides for additional desensitizing action.
