What is the minimum ASA number where a written or oral medical consultation is required before tx?

• A. ASA 1
• B. ASA 2
• C. ASA 3
• D. ASA 4

Answer: (C)

The ASA status system ranks patient health from healthy to life-threatening disease. A healthy patient is ASA I, a patient with mild systemic disease is ASA II, a patient with severe systemic disease that limits activity is ASA III, and a patient with severe systemic disease that constantly threatens life is ASA IV. When sedation or dental treatment is planned, the risk rises as systemic disease becomes more significant. Because severe systemic disease that limits daily activity can alter how a patient responds to sedation and stress, a medical input is advised to ensure safety. Therefore, the minimum level at which a written or oral medical consultation is warranted before treatment is ASA III. This allows the clinician to confirm optimization and tailor the plan with physician input. ASA I and II typically don’t require formal medical consultation for routine cases, while ASA IV or higher would necessitate even more comprehensive medical coordination.
