1. Color
   • Translucent
   • Color varies from yellowish-white to greyish white
2. Thickness
   • Maximum thickness is seen on the cusps of molars and premolars
   • Thin at the neck region
3. Hardness – 350 KHN
4. Specific gravity – 2.8
5. Modulus of elasticity – higher at the surface
6. Density – decreases from surface to deeper regions
7. Conductivity
   • Insulator at room temperature
8. Resistance
   • Temperature resistance – 5-13 Hz
   • Electrical resistance – 10 15 to 10 5 ohm
9. Permeability
   • It acts as a semipermeable membrane

Enamel Chemical properties:

• The enamel consists of approximately 96% mineral and 5% organic material and water
• The inorganic content of enamel is a crystalline calcium phosphate-hydroxyapatite
• Various ions – strontium, magnesium, lead, and fluoride are incorporated into it
• The susceptibility of these crystals to dissolution by acid provides the chemical basis for dental caries
  • The organic material consists of proteins – 2 main groups are seen Amelogenin
  • Nonamelogenin
