In the Universal Numbering System, which number represents the maxillary right lateral incisor?

  1. 6

  2. 7

  3. 8

  4. 9

The correct answer is: 7

In the Universal Numbering System, each permanent tooth is assigned a specific number, starting from the maxillary right third molar and moving sequentially around the arch to the maxillary left third molar, then continuing to the mandibular left third molar and back to the mandibular right third molar. The maxillary right lateral incisor is positioned to the left of the maxillary right central incisor. In this system, the maxillary right central incisor is numbered 7, and directly to its right, the maxillary right lateral incisor is assigned the number 8. Hence, in this context, the number that represents the maxillary right lateral incisor is accurately identified as 8. This numbering convention helps dental professionals communicate clearly about specific teeth during diagnosis, treatment planning, and documentation. Understanding this system is critical for efficient dental practice and coordination of patient care.
