In which stage of tooth development is a geminated tooth formed?
Show answer and explanation
Correct answer: D. Proliferation (bud stage)
- A. Incorrect – initiation disturbances cause anomalies of NUMBER (anodontia, supernumerary teeth), not a divided single bud.
- B. Incorrect. Gemination arises from an attempt of a single tooth germ to divide during the proliferative (bud) stage of development, well before apposition/maturation of hard tissues.
- C. Incorrect – histodifferentiation disturbances affect tissue type/structure (e.g., amelogenesis/dentinogenesis imperfecta), not tooth number/twinning.
- D. Correct – gemination is an abortive attempt of a SINGLE tooth bud to divide, a proliferation-stage disturbance (the final crown shape is then expressed through morphodifferentiation).
