Role of Community Based Fluoride Delivery in Caries Prevention Flashcards
how does fluoride prevent caries
promotes remineralisation
fluoroapatite less susceptible to demineralisation
topical effect greater than systemic
most effective on early lesions
what are the 2 types of oral reservoir for fluoride
mineral deposits in saliva
calcium fluoride
what are the community fluoride therapy
water
school based brushing
varnish
what are the in office fluoride methods
varnish
gels and foams
slow release
what are the home fluoride methods
toothpaste
mouthrinse
tablets
what is the effect of fluoride mouthrinses
reduction in caries of around 30%
what is an acidulated mouthrinse
low pH which makes demineralisation so presence of fluoride in mouthwash can promote remineralisation
more effective than non acidulated
what is a fluoride booster
CPP-ACP
what is the fluoride concentration of duraphat fluoride varnish
22600ppmF
what are the factors determining the anticaries activity of fluoride toothpaste
fluoride concentration
frequency of application
rinsing behaviours
when brushing takes place
what is the effect of fluoride concentration
6-7% reduction in caries for every 500ppmF increase
what are the optimal brushing habits
twice daily
no rinsing
1500ppmF paste
how much fluoride is needed to risk fluorosis
0.1mg/kg body weight
what is the efficacy of fluoride dependent on
concentration
how do you maximise caries benefit but reduce fluorosis risk in young children
keep toothpaste out of reach of young children
brush frequently
supervise brushing by young children
use small amount of paste
discourage swallowing
encourage spitting out
