Which supervision level requires the dentist to be present in the treatment room to oversee intraoral or chairside services?

• A. Personal supervision
• B. Direct supervision
• C. General supervision
• D. Indirect supervision

Answer: (A)

The level being tested is the one where the dentist must be physically present in the treatment room during intraoral or chairside procedures. This arrangement allows the dentist to directly observe, guide, and intervene in real time, ensuring safety, accuracy, and immediate professional oversight as the procedure is performed. Other supervision levels differ in where the dentist must be located—whether in the same building, in the operatory but not necessarily in the room, or not required to be on-site—so they do not guarantee the in-room presence that characterizes this level.
