18
Q

how much fluoride avg in water

A

1 ppmF

19
Q

what are the avg.’s of fluoride in toothpastes

A

1100-1500 ppmF

prescribed 2800-5000ppmF

20
Q

what are some rinses with fluoride

A

daily - 250 ppmF (0.05%)

weekly - 1000pmF (0.2%)

21
Q

how much fluoride in avg varnsh

A

22,600 ppmF (duraphat)

22
Q

what does the majority of water fluoridation results show

A

reduces inequalities in dental health

fluorosis prevalence and publics perception

23
Q

what is fluoride advice from birth to 3 years

A

twice daily brush
parent brush
us smear toothpaste not less than 1000 ppmF

24
Q

what si the flurde advice from 3-6 years

A

brush last night nd other
supervised
pea sized 1000-1500 ppmF
spit out no rinse

25
Q

what is imp about fluoride supplements

A

caries inhabiting potential
compliance needed
individual basis

26
Q

what si he fluoride like in teeth

A

few 1000 ppmF matrix formation and maturation

27
Q

what are the effects of fluoride

A

proton pump commensal flora
decreased solubility product
decreased fissure depth
raise pH

28
Q

what are fluoride containing filling materials

A 
glass ionomer cements 
fluoride releasing composites 
compomers
prolonged release
fluoride reservoir
29
Q

what is CPP-ACP

A

calcium amino acids attach to biofilm

collects bioavailable calcium nd phosphate

30
Q

what si the role of CPP-ACP

A

maintain local supersaturated environment with respect to claim and phosphate

31
Q

what is fissure sealant uses

A

caries prevention - placed in pits and fissures

non caveatted carious lesions

32
Q

resin vs Glass ionomer cement

A

resin based - first choice

GIC - interim

33
Q

what are caries vaccines

A

active immunisation
Ab in gingival crevicular fluid
successful animals

34
Q

what is secondary caries detection not reliably predicted by

A

ditching around amalgam fill

staining around restoration

35
Q

what is secondary caries predicted by

A

reliably detected by a caveatted lesion can’t be cleaned and bitewing radiograph
