Study Notes
Dentine Composition and Structure
- Dentine is primarily composed of inorganic minerals (approximately 70%) and organic material (approximately 20%).
- The inorganic component is primarily calcium hydroxyapatite, with crystals smaller than those found in enamel.
- The organic component is largely a collagenous matrix (about 18%).
- A smaller portion of the organic material consists of non-collagenous proteins and lipids.
