On which tooth number is the star located in the first example?

• A. 11
• B. 9
• C. 24
• D. 14

Answer: (A)

The star sits on the tooth located in the upper front on the left side, specifically the canine. In the universal tooth numbering system used for these exams, the upper arch is numbered from the rightmost third molar to the leftmost third molar, and the tooth at that position corresponds to number 11. So the star marks the maxillary left canine, tooth number 11. The other possible placements (like a central incisor or a molar) don’t align with the star’s shown position in the image.
