Study Notes
Inorganic Content of Enamel
- Enamel comprises approximately 95% inorganic material, primarily hydroxyapatite crystals, which provide hardness and durability.
- The remaining 5% consists of organic matrix and water, contributing to enamel structure and integrity.
Origin of Enamel
- Enamel originates from ameloblasts, specialized epithelial cells responsible for enamel formation.
- It develops during the tooth development process, specifically in the enamel organ.
Non-Sensitivity of Enamel
- Enamel does not have nerve endings or blood vessels, making it non-sensitive.
- Its primary function is to protect the underlying dentin and pulp, which contain the sensory nerves.
Fate of Ameloblasts After Tooth Eruption
- Ameloblasts undergo apoptosis (programmed cell death) once tooth eruption is complete.
- This termination prevents further enamel formation, as enamel is a non-renewable tissue.
Phase of Amelogenesis with Complete Mineralization
- The maturation phase of amelogenesis is where complete mineralization of the enamel matrix occurs.
- This stage involves the transition of enamel from a less mineralized state to a fully hard and mineralized state, essential for enamel strength.
