In Palmer's Notation, UR5 corresponds to which tooth category?

• A. Upper Right Central Incisor
• B. Upper Right Second Premolar
• C. Upper Left Second Premolar
• D. Upper Right First Molar

Answer: (B)

Palmer notation uses a quadrant indicator with a number 1–8 in that quadrant to identify each tooth from the front to the back. UR means the upper right quadrant. The numbers follow the order: 1 central incisor, 2 lateral incisor, 3 canine, 4 first premolar, 5 second premolar, 6 first molar, 7 second molar, 8 third molar. So in the upper right quadrant, the number five points to the second premolar. Therefore the tooth category is premolar, specifically the upper right second premolar.
