Study Notes
Parts of the Tooth
- Crown: Visible part in the oral cavity, covered by enamel.
- Root: Hidden portion below the gum line, covered by cementum.
- Apex: Rounded tip of the root.
- Periapex: Surrounding area of the root apex.
- Foramen: Opening at the apex for blood vessels and nerves.
- Furcation: Section of multi-rooted teeth where roots branch.
Tooth Layers
- Crown Composition: Contains pulp, dentine, and enamel.
- Root Composition: Comprises pulp, dentine, and cementum.
- Enamel: Hardest tissue (96% mineralized), protects the dentine in the crown.
- Dentine: Main body of the tooth (70% mineralized), surrounds the pulp beneath enamel and cementum.
- Pulp: Innermost layer, non-calcified, contains blood vessels, nerves, and lymphatics.
- Cementum: Bone-like tissue covering the root's dentine (50% mineralized).
Oral and Dental Anatomy
- Oral anatomy is fundamental for dental sciences and practices.
- Oral structures reflect both local and overall systemic health.
- Understanding anatomy aids in evaluating tooth relationships within both arches.
- Oral tissues serve as indicators of a person's oral and general health status.
- Variations in color and morphology of oral structures can occur due to genetics and aging factors.
