2. *F is wide spread in nature in : sea water , fish
,
vegetable , milk ,tea & organic compound.
*It deposited in bone & excreted by kidneys
*Used in caries reduction when it is
maintained consistently in oral environment.
*most effective in proximal & smooth surfaces.
3. 1/topically promote remineralization & reduce
demineralization in presence of calcium &
phosphate in solution.
2/prevention of caries need lifelong exposure.
3/increase fluorapatite & decrease carbonated
apatite make enamel >resistant to caries than
original enamel (concentration wanted is
<,1ppm).
4/
4. 4/affect glycolytic pathway of oral microorgs
reduce acid production & interfering with
enzymatic regulation of carbohydrate
metabolism which reduce the accumulation of
intracellular & extracellular polysaccharide.
5/
5. * It is the general increase in availability of
fluoride from foods , beverages , toothpaste ,
and topical agents which is in low fluoridated
communities which can benefit from the wide
spread distribution of these product from
fluoridated communities where they have been
manufactured.
7. *CONTROLLED addition of fluoride in public
water supply (conc. b/w 0.8 & 1ppm)
*Advantage:
Effective , efficient , low cost & extended to
many people.
*Caries reduction : 20-40%
8. *Sodium fluoride tabs used as water
supplement (1 mg F) dissolve in 1L of water.
*school water fluoridation :
Using high level of F e.g:5ppm
9. *Factors to be considered before fluoride
application:
-caries risk
-cariogenicity of diet
-pt. age & compliance
-use of systemic & topical F modalities
-community water F
-existing medical conditions
11. •
Children below 5 yrs conc. 400-500ppm
•
*6 or more 1000ppm
•
*young child under 6 yrs presents with
caries , toothpaste of at least 1000ppm is
indicated
•
*teenage , adult at higher caries risk F conc.
1500 ppm or more
12. *The most common F compound used is
sodium fluoride .
*0,05 % SF (225 ppm F) for daily use
*0,2% (900-910ppm) weekly.
13. *Indications:
1/pt with ortho appliance.
2/pt with post-irradiation hyposalivation.
3/pt unable to perform adequate tooth brushing.
4/pt with high risk of caries.
*CONTRAINDICATION:
CHILDREN < 6YRS
14. *INDICATIONS:
1/ORTHODONTIC PTS.
2/PT with decreased salivary flow.
3/children whose permanent molars cannot be
sealed.
-apply the gel on tray and held it for 4
minutes(professional use).
(home use):lesser concentration of F , applied by
tray or brush.-
15. -PROVIDE PROLONG CONTACTTIMES B/W
FLUORIDE & ENAMELTO RAISE FORMATION OF
FLUOROAETITE.
-EFFECTIVE FOR 1RY & 2RY DENTITION.
*INDICATIONS:
1/hypersensitive area.
2/newly erupted teeth.
3/local remineralization of which spot lesion.
4/high risk pt.
16. -duraphat(5%22600ppm)remain up to 12-
48hrs.
-fluor protector(ivoclar vivadent).
*how to apply:
-remove plaque and stain thoroughly.
-plaque is recycling reservoir for F.
-dry teeth to facilitate adhesion.
23. -ESTIMATE F digested amount.
-minimize further absorption.
-remove F from body fluid.
-support vital signs.
*If vomiting has not occurred spontaneously :
-give milk.
-give 5% ca gluconate lactate or milk of magnesia.
-hospital advice.
