FUNCTIONS QUESTIONS WITH
DETAILED VERIFIED ANSWERS
False; because its 1ppm Ans: T/F: the recommended level of fluoride in
drinking water is 2ppm
True Ans: T/F: enamel that is treated with fluoride replaces the hydroxl
ion to the fluorapatite crystal
True Ans: T/F: Fluoride is absorbed in small quantities from the stomach
and small intestine
False; kidneys Ans: T/F: Excess fluoride not absorbed is excreted
through the liver
True Ans: T/F: The uptake of fluoride is the highest just after the tooth
has erupted and tapers when the enamel matures
True Ans: T/F: Fluoride creates remineralization on decalcified areas
False, systematically & topically Ans: T/F: Fluoride is made available to
the teeth systematically only
False Ans: T/F: The presence of plaque prohibits the uptake of fluoride
False Ans: T/F: Fluoride increases the ability of plaque to produce acid
True Ans: T/F: Dryness of the teeth contributes to the effectiveness of
gel or foam fluoride.
true Ans: T/F Brown stains occur in areas of decalcification.
