Same patient. What is the correct treatment sequence?

Correct answer: A. Prophylaxis → Extractions → Orthodontics → Prosthetics

• A. Correct. Standard treatment sequencing begins with disease control/hygiene (prophylaxis), followed by any necessary extractions, then definitive orthodontic tooth movement, and finally prosthetic restoration once teeth are positioned.
• B. Performing extractions before basic prophylaxis/disease control is out of standard sequence.
• C. Performing orthodontics before necessary extractions (when extractions are part of the plan) is generally out of sequence, since space management typically requires extractions to be completed first.

Note: All options included extractions. Standard sequence: emergency/hygiene control first, then definitive treatment.
