Study Notes
- Enamel is the hardest biologic tissue and covers the anatomical crowns of teeth.
- Enamel needs dentin for support and provides the shape and contour of teeth.
- Enamel is non-vital tissue and does not undergo repair from carious lesions or trauma.
- Enamel is permeable to a certain extent and has a specific gravity of 2.8.
- Enamel is composed of inorganic material (96-98%) and organic substance (2-4%).
- Enamel rods are the basic structural unit of enamel and originate at the DEJ.
- Enamel rods have a highly organized pattern of tightly packed hydroxyapatite crystal orientation.
- Gnarled enamel rods offer the greatest resistance to the cusps and incisal areas.
- Enamel rod sheaths contain more enamel protein and recrystallized hydroxyapatite crystals for acid resistance.
- Interrod enamel is the substance that cements the rods together.
