Nutrition and Balanced Diet Flashcards
Nutritional Effects are … pre-eruption and … post-eruption
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
