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

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

Answer: (C)

The main idea is in-room, hands-on oversight. Personal supervision requires the dentist to be physically present in the treatment room while the assistant or hygienist performs intraoral or chairside services. This direct presence lets the dentist directly guide technique, intervene immediately if something appears off, and ensure all procedures stay within the allowed scope for that patient and setting. Other supervision levels involve the dentist being in the building or otherwise available without being in the room, so they don’t provide that same immediate, in-room oversight.
