What are the three ways fluoride prevents caries?
inhibits bacteria, inhibits demineralization, enhances remineralization by creating a surface that is caries resistant (fluoroapatite)
True or False, fluoride varnish is only to be used within a dental office, not at home
True.

In the blood, what does fluoride combine with?
calcium
When fluoride combines with calcium in the blood, what condition results?
hypocalcemia (muscle spasms)
True or False, fluoride in the nervous system can cause paresthesais
True (this is loss of sensation and numbness)
What is the range, in mg/kg of body weight, where fluoride is lethal in an acute dose?
32 to 64 mg of fluoride per kg of weight

certain lethal dose
the certain lethal dose (CLD) of fluoride for an adult is ??g and a child is ??g
5-10g, .5-10g

milk and lime water (CaOH2)
Dental fluorosis is (hypo, hyper)mineralization of enamel resulting from excess fluoride
hypomineralization
True or False, fluorosis results from excess topical fluoride
False, excess ingested fluoride!
True or False, diet drinks are ok because they don't have acid
false, they DO have acid!
Which acid in soda adds a sharper flavor and is linked to decreased levels of bone density?
phosphoric acid

What are the 3 types of fluoride?
Acidulated phosphate Fluoride (APF), Neutral sodium fluoride (NaF), Stannous Fluoride (SnF2)
What is te benefit of using acidulated fluoride?
It etches the enamel a bit so the fluoride is taken up easily
Between acidulated fluoride and sodium fluoride, which is taken up more rapidly?
acidulated (APF)
What is the main downside to acidulated fluoride with someone who has restorations?
It can damage the restorations
True or False, Sodium fluoride shows no adverse effects to intraoral restorations
True.
True or False, sodium fluoride is best option for patients with restorations
True.

SnF2
True or False, NaF poses no stain risk
True. (SnF2 however, can stain)
