Question 3 of 3

Yes, the TRUE statement is:

The fluoride varnish will set upon contact with saliva

The other statements are false because:

A thorough oral prophylaxis is NOT necessary prior to applying fluoride varnish to primary teeth - toothbrushing may be sufficient to clean the teeth before application

Application time is between 1 - 4 minutes, depending on the number of teeth that are to be covered with varnish

Fluoride varnishes should be applied at least every 2 - 3 months on the at-risk-for-caries child. Other application regimens include an intensive treatment protocol of 3 applications in 1 week every year (for 3 - 4 years).
