Chapter 35 Flashcards
Why is fluoride important?
Helps aid in sensitivity reduction. Plugs up tubules, helps strengthen enamel by demineralization
How is fluoride delivered?
Topically (trays, gel, rinse) orally (tablet)
What is the summary of fluoride action?
Inhibit demineralization, enhance remineralization, inhibit bacterial activity by inhibiting emulate an enzyme needed by bacteria to metabolize carbohydrates.
What is fluoridation?
Adjustment of the natural fluoride ion content of a domestic municipal water supply
What is defluoridation?
When fluoride is removed from a community water supply.
What does table 13-1 include?
1
What are risk factors for fluoride treatments?
1
Which foods contain fluoride?
1
2.0 % sodium fluoride?
Trays or foam (porcelain)
1.23% acidulated phosphate
Gel or foam apply a thin layer
5% sodium fluoride NaF neutral or or 7 pH
Varnish, apply a thin layer
Varnish technique?
1
Tray technique?
1
Take home tray technique?
1
Who are fluoride mouthrinses indicated for?
Self application for individuals at moderate or high caries risk, pt’smwitn areas of demineralization, root exposure.
Who are the trays indicated for?
I
Who are fluoride dentifrices indicated for?
Caries prevention
Fluoride safety?
Toxic overdose should be avoided
What are signs of fluoride overdose?
Nausea, vomiting, diarrhea, abdominal pain, increased salivation thirst.
What is chronic toxicity?
long-term ingestion of fluoride in amounts that exceed the approved therapeutic level
What is dental fluorosis?
Y
True or False
Epidemiological evidence shows maximum caries inhibiting affect when there is systemic exposure before tooth eruption, and frequent topical exposure throughout life.
True
True or False
Milk binds to fluoride
True
True or False
Fluoride is rapidly absorbed by passive diffusion in the stomach
True (most is absorbed within 60 minutes)
True or False
The fluoride ion (F) is stored as an integral part of the crystal lattice of teeth and bones. The amount varies with the amount of intake, exposure, age, stage of development of the individual.
True
Definition of abrasive system
substances with cleaning and polishing properties utilized in the formulation of a dentifrice; to be compatible with fluoride compounds and other ingredients and not alter the tooth structure unfavorably
Definition of acidogenic
producing acid or acidity
Definition of apatite
a group of minerals of the general formula wherein the X might include hydroxyl (OH), carbonate (CO), fluoride (F), or oxygen (O); crystalline mineral component of hard tissues (bones and teeth)
Definition of hydroxyapatite
the form of apatite that is the principal mineral component of teeth, bones, and calculus
Definition of fluorapatite
the form of hydroxyapatite in which fluoride ions have replaced some of the hydroxyl ions; with fluoride, the apatite is less soluble and therefore more resistant to the acids formed from carbohydrate intake
Definition of fluorhydroxyapatite
apatite formed when low concentrations of fluoride react with tooth mineral; at higher concentrates, calcium fluoride is formed
