that is applied over the
occlusal pits and grooves
of the teeth
What is the process by
which fluoride prevents
decay?
Slowing demineralization
and enhancing
remineralization of tooth
surfaces
What are the two routes
or means by which the
body receives fluoride?

Topical fluoride is applied in
direct contact with the teeth
What is the name of the
dental condition that
results from too much
fluoride?
fluorosis
What precautions are
necessary for children
who use fluoridated
toothpaste?
Adult supervision of young children during toothbrushing is necessary, and the child should be instructed not to swallow the toothpaste.
What is the key dietary
factor that relates to
dental caries?
Dental caries cannot
occur without dietary
sugars
