In resorption of roots of the primary teeth, the dental pulp_____________?
Correct answer: D. Plays a passive role
- A. Aids in formation of secondary dentin slowing down resorption
- B. Becomes a fibrotic non-vital mass
- C. Initiates resorption from the inner surface of roots
- D. Plays a passive role
Explanation
Physiological resorption of primary roots is carried out mainly by odontoclasts on the external root surface, while the dental pulp generally remains a passive participant. It does not initiate resorption from the inner surface, and pulp fibrosis or secondary dentin formation is not the usual mechanism.
