systemic
topical
What Mineral in Excess leads to Fluorisis
Fluoride
How does Vitamin D Affect Caries Susceptibility?
-disturbs calcium and phosphate metabolism
-enamel hypoplasia
How does Protein Malnutrition Affects Caries Susceptibility?
decreases in salivary flow
less enzymes
How can Pyruvate from Carbohydrates be Cariogenic ?
pyruvate into lactic acid, acetic acid, formic acid
lower pH
demineralisation
How can Fruit be Cariogenic?
extrinsic sugars and acidity
What is the Most Cariogenic Carbohydrate?
sucrose
Sucrose+ Glucan ? and by Which Enzyme?
Sucrose + Glucan ➤ Glucan + Fructose
by glucosyltransferase
Sucrose + Fructan
Fructan + Glucose
by fructosyltransferase
Glucan and Fructan are … Polymers
Plaque
pros and cons about sugar subs
mostly non-cariogenic
calorific, osmotic diarrhoea
Define Cariostatic
halts the development of dental caries
How is Milk (4), Cheese (3), Chocolate and Liquorice Cariostatic?
Milk
- calcium and phosphate - remineralisation
- non-casein protein - bind to enamel surface and protect against acid attack
- casein - bind and stables calcium phosphate
- inhibit S.mutans adhesion
Cheese
- calcium and phosphate - remineralisation
- increase pH
- increase salivary flow
Chocolate
- cocoa factor is anticariogenic
Liquorice
- glycyrrhizic acid is anticariogenic BUT causes electrolyte imbalance
Tannins, Black + Green Tea
How is Tea Cariostatic?
Tannins (Polyphenols) inhibit salivary amylase
- reduce cariogenic potential of starch
- tannic acid inhibit growth of S.mutans
black and green tea:
contain flavonoids - type of catechin (polyphenols)
- inhibit growth of bacteria
- prevent adherences and growth of plaque bacteria
Why is Frequent Eating Bad for teeth?
increased length of time exposed to acidic conditions
Why is being Dehydrated Bad for Teeth?
Reduced salivary flow rate
