Q

How is Milk (4), Cheese (3), Chocolate and Liquorice Cariostatic?

A

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

Q

Tannins, Black + Green Tea

How is Tea Cariostatic?

A

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
