At approximately what age do maxillary permanent central incisors typically erupt according to the data?

• A. 6 years
• B. 7 years
• C. 9 years
• D. 17 years

Answer: (B)

Maxillary permanent central incisors typically erupt during the early mixed dentition, around seven years of age. This timing aligns with the period when the primary maxillary central incisors are finishing shedding and the resorption of their roots opens a path for the permanent successors. Eruption charts commonly show an average near seven years, with a typical range from about six to eight years. So, seven years best represents the standard data. Ages like six or nine are outside the central tendency for these teeth, and seventeen is far beyond the eruption window for permanent dentition.
