Question 8

hydroxyapatite is what we want to _____

Answer 8

remineralize

Question 9

has a hexagonal, lattice striation and hydration shell

Answer 9

hydroxyapatite

Question 10

enamel is __% hydroxyapatite and __% water

Answer 10

97%, 3%

Question 11

enamel prisms/rods ____ um and interprismatic area ___um

Answer 11

4-8um, .1um

Question 12

Surface demineralization AKA ___

Answer 12

surface softening

Question 13

first 10um of demineralization

caused by acids in food/bev. - citric acid and hydroc from our stomach

Answer 13

surface demineralization/ surface softening

Question 14

sub surface demineralization AKA __

Answer 14

caries lesion

Question 15

20um surface lesion, 20-1000um lesion body
biofilm induced
pH 4.5-6.5

Answer 15

sub surface demineralization/caries lesion

Question 16

10-20 sec of a strong acid

clean/roughen tooth surface

Answer 16

etch enamel demineralization

Question 17

etch demineralization is a stronger or weaker demin than surface demin

Answer 17

stronger

Question 18

true or false: dentin can have extensive dentin demineralization without a lot of enamel demin present

Answer 18

TRUE in fissure demineralization. This is why fluoride and remineralization treatments are more effective for smooth surface lesions

Question 19

our goal for remineralization: remineralize ____ first

Answer 19

body of lesion first, THEN surface area

Question 20

ion deposition via saliva, biofilm, tooth into voids (any intercrystal or interrod spaces caused by dissolution) to produce a net mineral gain

Answer 20

definition of remineralization

Question 21

remineralization NEEDS

- bioavailable calcium and phosphate (mainly from saliva)

Answer 21

thats all

Question 22

remin NOT possible if

Answer 22

lesions has become cavitated

Question 23

fluoride increases the deposition rate by a factor of

Answer 23

2-3

Question 24

fluoride actually becomes incorporated into the mineral as

Answer 24

flurohyroxyapatite

Question 25

what results in: reduced acid solubility of remineralized enamel and development of fluoride gradients

Answer 25

fluoride incorporating into the mineral

Question 26

theraputic remin by fluoride: up mineral saturation
CPP-ACP: helps to maintain ionic phos/calcium supersaturation
-electroneutral : can remin from bottom up

Answer 26

hehe

Question 27

helps to maintain ionic phos/calcium supersaturation

Answer 27

CPP-ACP
