Correct answer: B. Exforliation of teeth occur
- A. Ankylosis may occur
- B. Exforliation of teeth occur
- C. Delayed eruption
- D. No change occurs
Explanation
Without cementum, periodontal ligament fibres cannot attach properly to the root surface, so the tooth may eventually loosen and exfoliate. Ankylosis is fusion of cementum or dentin to alveolar bone, not the expected result of absent cementum.
