Which tooth has the LEAST chance of erupting ectopically?
Show answer and explanation
Correct answer: C. Mandibular lateral incisor
- A. Incorrect – mandibular second molars not uncommonly tip/impact mesially and erupt ectopically.
- B. Incorrect – the maxillary first molar is the classic ectopically-erupting tooth, often resorbing the distal of the second primary molar.
- C. Correct – mandibular lateral incisors rarely erupt ectopically. Ectopic eruption overwhelmingly involves the maxillary first molars and maxillary canines (and mandibular second molars to a lesser extent).
- D. Incorrect – the maxillary canine is one of the most commonly impacted/ectopic teeth (long eruption path).
