Quizlet Qs Flashcards
Caries
bacterial infection of mineralised tooth tissues
Gingivitis
inflammation of gingival tissues at neck of the tooth
what does food debris and bacteria form ?
Plaque
stagnation areas are?
plaque sticks where it is not easy to dislodge - gingival margins
what does plaque allow?
bacteria in plaque turns sugar into weak acids that’s dissolve enamel
main microorganism for caries ?
streptococcus mutans
carcinogenic food?
carbohydrates- turn into acid
NMESs?
artificially added to food
worst NMESs ?
sucrose and glucose (dextrose)
intrinsic sugars?
natural - in fruit (fructose)
milk extrinsic sugars?
lactose/sucrose/glucose
how long are acid attacks?
up to 20mins
PH of saliva
PH7
what ph does weak organic acid attack
PH5.5
What is the healing phase called
remineralisation
1st stage of caries
white spot lesion
2nd stage of caries
frequent acid attacks, follows prism structure of enamel and eats exposed cementum
3rd stage of caries
demineralisation
4th stage of caries
deep in enamel, reaches ameleodenralinate junction
What is the Ameleodenralinate Junction?
caries hits where enamel and dentine meet
what forms dentine
ondontoblast cells
Accute inflammation?
heat/swelling/redness/pain/loss of function

partial anadontia?
less teeth than normal
what do low inorganic ions do to saliva ?
watery saliva, little protection but still stops plaque build up
