Fluoride

Question 1

Systemic Fluoride

Answer 1

PRE ERUPTION, ingested. water @ .7ppm, rX, vegetables, canned foods, formula

Question 2

Fluoride Absorption

Answer 2

distributed by plasma, 50% deposited in teeth/bones, 50% excreted via kidneys

Question 3

Systemic Fluoride and Tooth Development

Answer 3

happens during mineralization (DEJ) and maturation (surface) > caries resistance

Question 4

Fluorosis

Answer 4

occurs during mineralization phase - small white spots (hypocalcification) or brown staining/pitting (hypoplasia)

Question 5

Daily Recommended Systemic Fluoride Dose

Answer 5

1ppm = 1/2 mg

Question 6

Fluorapetite Crystal

Answer 6

Carbonated hydroxyapetite crystal + fluoride

Question 7

Benefits of Topical Fluoride

Answer 7

inhibits demineralization, enhances remineralization, inhibits caries process

Question 8

Cariogenic Biofilm

Answer 8

Strep mutans, lactobacilli

Question 9

Professionally applied fluoride: Gel

Answer 9

2.0% NaF 9,050ppm; 1-4 min application; no food/drink 30 min

Professionally applied fluoride: Varnish

Answer 11

5% 22,600ppm; do not brush for 4-6 hours, no hard foods/ hot liquids - *“ROSIN” TREE NUT, PINE NUT OR TREE ALLERGIES

Question 12

Prevident: Dry Mouth

Answer 12

1.1% NaF, 1x day

Question 13

Prevident: Booster

Answer 13

1.1% NaF, high caries risk or ortho, 1x/day

Question 14

Prevident: Sensitive

Answer 14

1.1% NaF, 5% Potassium Nitrate, 2x/day

Question 15

Chlorhexidine

Answer 15

.12% Chlorhexidine Gluconate rinse for high caries risk, high bacteria- kills s.mutans *doesnt work in conjunction w other fluoride denitrifies

Question 16

Xylitol

Answer 16

inhibits s.mutans, stimulates salivary flow, looks/tastes like sucrose, reduces biofilm formation

Question 17

Sodium Bicarbonate

Answer 17

baking soda, neutralizes acid, antibacterial. use for: low salivary flow, acid reflux, bulimia, morning sickness

Question 18

Remineralization Elements

Answer 18

fluoride, calcium, phosphate

Question 19

Role of Saliva

Answer 19

remineralization, neutralizes acids, discourages bacteria growth, protects surfaces, aids chewing/swallowing, clears food

Question 20

Salivary Stimulants

Answer 20

xylitol, foods that require mastication (apple, carrot, celery), citric acid

Question 21

Salivary Substitutes

Answer 21

water, glycerine, gels
