Which supervision level requires the dentist to be physically present during the procedure?

• A. Direct Supervision
• B. Indirect Supervision
• C. General Supervision
• D. None of the above

Answer: (A)

Direct supervision is the level where the dentist must be physically present in the treatment area during the procedure. This on-site presence allows the dentist to directly observe what the hygienist is doing, provide immediate guidance, and personally approve the work before the patient leaves. That immediate, in-room oversight is what distinguishes it from the other levels of supervision.

Under indirect supervision, the dentist is available to supervise but does not have to be in the operatory; they may be in the office and reachable for consultation. General supervision means the dentist has authorized the procedure but does not need to be present at the time of the procedure at all. Therefore, only the direct supervision level requires the dentist to be physically present during the procedure.
