What is the order of permanent tooth eruption for the maxillary arch?

• A. 1M, CI, LI, C, 1PM, 2PM, 2M, 3M
• B. CI, LI, 1M, C, 1PM, 2M
• C. 3M, 2M, 1PM, 1M, CI, LI
• D. LI, CI, C, 2M, 3M, 1PM

Answer: (A)

The order of permanent tooth eruption for the maxillary arch is accurately represented by the sequence: first molar (1M), central incisor (CI), lateral incisor (LI), canine (C), first premolar (1PM), second premolar (2PM), second molar (2M), and third molar (3M).

This order is consistent with the general pattern of eruption that occurs around ages 6 to 13 for the maxillary permanent teeth. The first molar typically erupts first around the age of 6, followed by the central incisors and lateral incisors, which emerge between ages 7 and 8. The canine usually comes in around the age of 11, and the premolars follow suit shortly thereafter, with the second molar erupting around age 12 and the third molar generally last, often erupting in late adolescence or early adulthood.

This sequence provides a clear timeline for dental professionals to understand the development and eruption pattern of the maxillary teeth, aiding in assessment and treatment planning for young patients as well as in monitoring dental growth and development.
