1

what do teeth consist of?

calcium phosphatase crystals held together by a protein matrix

2

what is the mineral component in teeth known as?

hydroxyapatite

3

what is tooth erosion?

the direct effect of acid in the diet on our teeth

4

how to do chelating agents aid tooth decay?

they bind to calcium ions preventing remineralsation

5

in which way does fluoride reduce caries?

it stimulates remineralisation, reduces enamel solubility at low pH, inhibits baterial metabolism of carbohydrates

6

when fluoride combines with hydroxyapatite it forms a complex known as?

fluoroapatite

7

why is fluoroapatite more effective than hydroxyappatite?

fluoride ion is smaller than the hyroxyide ion so it fits better into the crystal, rendering it less soluble in acid
