Fusion of two tooth germs results in:

  1. One less tooth in the dental count
  2. One extra tooth in the dental count
  3. Two crowns sharing one pulp
  4. A tooth with an abnormal bend in its root
Show answer and explanation

Correct answer: A. One less tooth in the dental count

  • A. Correct. In fusion, two separate tooth germs unite to form a single tooth structure, resulting in one fewer tooth in the dental count (unlike gemination).
  • B. One extra tooth describes gemination where the count remains the same, not fusion.
  • C. Two crowns sharing one pulp describes gemination, not fusion.
  • D. An abnormal root bend describes dilaceration.
