1

Demineralisation of tooth tissue can occur by acids from what

Caries
Gustatory acids (reflux)
(apparently erosion but i swear this aint acids bruh)

2

Loss of tooth minerals can happen with tooth wear, give examples of tooth wear

Attrition
Abfraction
Abrasion

3

Caries form by a multifactorial process, name some of these factors

Diet
time
Plaque - tooth surface
Pellicle - oral bacteria

4

What is the formula for Calcium Hydroxyapatite

Ca10(PO4)6(OH)2

5

What is the critical pH

The pH at which saliva ceases to be saturated with respect to calcium and phosphate
Because the calcium and phosphate combine with the Hydrogen ions and remove them from the solution

6

Name some components of saliva

- Calcium and phosphate ions
- Calcium binding proteins
- Hydroxyapatite binding proteins
- water

7

Name some components of enamel

• Calcium and phosphate
• Calcium binding proteins
• Hydroxyapatite binding proteins
• water
