Correct answer: A — 16 years (when approximately two-thirds of roots are formed)
Elective extraction of asymptomatic impacted third molars is generally recommended when approximately two-thirds of the root is formed (typically age 16-18 years), as: (1) root formation is sufficient for surgical planning; (2) the bone surrounding the tooth is still relatively resilient (faster healing); (3) the roots have not yet fully formed (reducing IAN proximity risk); and (4) the roots are not yet curved or hypercementosed. Delayed extraction in older adults is associated with increased surgical difficulty, slower healing, and higher complication rates.
