A 5-year-old child already has an erupted permanent first molar, an erupted lower permanent lateral incisor, and an erupted upper permanent central incisor. How would you describe this child's dental development?

Correct answer: D. Advanced (accelerated) eruption

• A. Normal 5-year-olds are still in the primary dentition with no permanent teeth erupted yet.
• B. The child clearly has permanent teeth present, so 'primary dentition only' is incorrect.
• C. Delayed would mean permanent teeth erupting LATER than expected — the opposite of this child.
• D. Correct. Permanent first molars and mandibular central incisors normally erupt around age 6-7, and lateral incisors around 7-8. Seeing these erupted at age 5 is AHEAD of schedule — advanced/accelerated dental development.
