Which star-marked tooth number is the second largest?

Which star-marked tooth number is the second largest?

• A. 31
• B. 28
• C. 18
• D. 10

Answer: (B)

In permanent dentition, crown size follows a clear order: molars are the largest, with the first molar usually the widest, then the second molar, and finally the premolars and incisors being smaller. So when you’re asked which star-marked tooth is the second largest, you’re looking for the star-marked tooth that is a second molar in the view provided. The star-marked tooth with the number 28 corresponds to that second molar position in the diagram, making it the second largest among the marked teeth. The other numbers represent teeth that are typically smaller in crown width (incisors and premolars), so they wouldn’t be the second largest.
