Fusion of two adjacent teeth typically results in which finding on tooth count?

  1. One fewer tooth than normal in the arch
  2. One extra tooth
  3. No change in count
  4. Two fewer teeth
Show answer and explanation

Correct answer: A. One fewer tooth than normal in the arch

Fusion joins two tooth germs into a single larger tooth, so the arch has one fewer tooth than expected. Gemination, by contrast, is one tooth germ splitting and counts as a normal number.Other options: Fusion does not add teeth or leave the count unchanged; it reduces the count by one.Key exam takeaway: Fusion = one fewer tooth (count is short by one); gemination = normal count.
