This high-yield revision note on Enamel vs Dentin vs Cementum: Histology Comparison Chart for INBDE covers everything examiners typically test under Oral Anatomy & Histology — structured as quick-reference tables, clinical correlations, mnemonics and previous-year-style high-yield points. It's built for last-mile revision before NEET MDS, INI-CET MDS and INBDE, so you can scan it in minutes instead of re-reading a whole textbook chapter.
| Feature | Enamel | Dentin | Cementum |
|---|---|---|---|
| Origin | Ectoderm (ameloblasts) | Ectomesenchyme (odontoblasts) | Ectomesenchyme (cementoblasts) |
| Mineral content | 96% (hardest tissue in body) | 70% | 45-50% (similar to bone) |
| Regeneration | None (acellular after eruption, cannot regenerate) | Yes (secondary/tertiary dentin by odontoblasts) | Yes (cementoblasts persist on surface) |
| Structural unit | Enamel rods/prisms, hydroxyapatite crystals | Dentinal tubules with odontoblastic process (Tomes' fiber) | Sharpey's fibers embedded (PDL attachment) |
| Vascularity/Innervation | Avascular, no nerve supply | Sensitive (hydrodynamic theory - fluid movement in tubules stimulates pulpal nerves) | Avascular, no nerve endings (mostly) |
| Sensitivity mechanism | N/A | Hydrodynamic theory (Brannstrom) - most accepted | N/A |
