In the Universal Numbering System, what tooth number represents the Maxillary right central incisor?

• A. 7
• B. 8
• C. 9
• D. 1

Answer: (B)

In the Universal Numbering System, the Maxillary right central incisor is assigned the number 8. This system starts with the upper right third molar as tooth number 1 and moves sequentially to the left across the upper arch to the upper left third molar, which is tooth number 16. The central incisors are then designated as number 7 for the Maxillary left central incisor (tooth to the left of the midline) and number 8 for the Maxillary right central incisor (tooth to the right of the midline). This numbering system is widely used in dentistry for its simplicity and clarity, allowing for easy identification of teeth during diagnosis and treatment.
