Lec 5 - Chart Entries and Diet/Dental Caries Flashcards
cell surface molecules of S. mutans
adhesin
polysaccharide part of S. mutans
glucans
s mutans have a high blank tolerance
acid
pH below blank starts demineralizing
5.5
cariogenic foods
bread, crackers, cereal, candy, cakes, sweets
noncariogenic foods
milk, cheese, fruits, vegetables, xylitol
favorite food of s mutans
monosaccharide carbs (glucose, fructose, galactose, ribose
sucrose, lactose, maltose are blank
disaccharides
disaccharides and monosaccharides are blank
soluble
carb with 3-10 monosaccharides
oligosaccharides
carbs that are long chains of monosaccharides like starch and cellulose
polysaccharides
rice, potatoes, and bread that are cooked are blank cariogenic
low
uncooked starch is blank cariogenic
low
finely ground or heat treated starch are blank cariogenic
more
all common mono, di, poly can be blank by oral bacteria
fermented
most cariogenic sugar of all
sucrose
sucrose is not only a substrate for acids but is also a substrate to produce blank
biofilm
fluoride binds to enamel crystal surface and transforms hydroxyapatite to more stable blank crystals
fluorapatite
fluroide causes blank of porous lesion and creates blank
remineralization, fluorapatite crystals
fluoride affects blank because it inhibits bacterial metabolism of sugar
plaque
this is a sugar alcohol that is used as a sweetener but cannot be fermented by cariogenic bacteria
sorbitol
another sugar alcohol that is non cariogenic but also degrades s mutans
xylitol
least acidogenic or cariogenic sugar
lactose
the blank in milk also helps in remineralizaiton
calcium
another part of dairy products that is anticariogenic
casein
