The dental pulp develops embryologically from which structure?
Show answer and explanation
Correct answer: A. Dental papilla
✓ A) Dental papilla is correct.
The dental papilla (ectomesenchyme-derived) forms the pulp and dentin (odontoblasts differentiate from the outer cells of the dental papilla). The dental follicle/sac gives rise to the periodontium (PDL, cementum, alveolar bone). The enamel organ (epithelial, from dental lamina) forms enamel (ameloblasts). The dental lamina initiates tooth development. Classic board mnemonic: Dental Papilla → Pulp + Dentin; Dental Follicle → PDL + Cementum + Alveolar bone; Enamel Organ → Enamel.
