In which dental anomaly does the pulp of two teeth appear to be shared?
Show answer and explanation
Correct answer: D. Gemination
- A. Incorrect. Dens in dente (dens invaginatus) is an infolding of enamel into the pulp space — a single tooth anomaly.
- B. Incorrect. Concrescence is union of two teeth by cementum only; pulp chambers remain separate.
- C. Incorrect. In fusion, two separate tooth buds join — they may have joined or separate pulp chambers, and tooth COUNT is reduced by one.
- D. Correct. Gemination = a single tooth bud attempts to divide. Results in a large bifid crown with a SHARED pulp chamber. Tooth COUNT is normal.
