Q

how does fluoride work

A

decreases demineralisation of enamel
increases remineralisation of enamel
incorporated in developing enamel
interferes with metabolism of some plaque bacteria

Q

why does the lesion appear chalky

A

due to the fact that light is refracted differently of those enamel porous crystals leaving a chalky appearance

Q

will demineralised enamel take fluoride up

A

yes

30
Q

where can we get calcium and phosphate from

A

saliva
dairy food
CPP-ACP mousse

31
Q

what is tooth mousse

A

made from casein
it is milk product to paste on teeth
very common

32
Q

what does CPP-ACP stand for

A

Casein phosphopeptide–amorphous calcium phosphate

33

what is the conc of fluoride varnish used in clinic

A

22600 ppm

35
Q

what do we apply at the surface enamel

A

high fluoride varnish

36
Q

what do we apply at the whole enamel lesion

A

water or simple toothpaste will remineralise the whole area

37
Q

what can high conc fluorides form

A

calcium fluoride

38
Q

what does fluoride do to bacteria

A

changes the bacterial pH- more acidic

also interferes with the glycolytic pathway

39
Q

how is fluoride incorporated in enamel

A

are fluoridated hydroxyapatite or as fluorapatite

40
Q

is this enough fluoride if it is only incorporated with crystals
