fluorides: types mechanisms clinical guidelines applications doxes and toxicity Flashcards
where do we have more dental decay
occurs in the north of England and Scotland
low socio economic areas
in ethnic minorities
what are some approaches to improve dental health
maintaining good dental care in those without decay
targeting resources to those that still develop decay
what are some groups in which we need to prevent dental caries
caries prone children
handicapped-medical and physical
low socioeconomic
immigrant groups
what does prevention include
Tooth brushing Diet control Fluoride Fissure sealants Regular dental check ups
what is the action of fluoride pre eruptive during tooth formation
decrease solubility of enamel
affects crown morphology making pits and fissures
what is the action of fluoride post eruptive
□ Inhibition of plaque bacterial enzyme system
□ Inhibits demineralisation when in solution
Enhances remineralisation by forming fluorapatite
where does apatite demineralise
pH of 5
when does apatite remineralise
pH of 7
when does fluroapaptite demineralise
3.5
what are examples of topical fluoride
Rinses Supplements Varnishes Toothpaste Gels Water, salt, milk
what are examples of systemic fluoride
water fluoridagtion
what is the optimum fluoridation Level
1ppm
describe fluoride tablets and drops
we do not file them in the UK
due to increased risk of fluorosis and toxicity
also pt compliance is low and they are not prescribed
how much percentage is the caries reduction by fluoride tablets and drops
20-80%
what are the children folumations of toothpaste
200-500ppm
