Which of the following correctly defines direct supervision?

Direct supervision is defined as the necessity for the dentist to be physically present in the treatment facility while the dental hygienist or dental assistant performs specific procedures. This level of supervision emphasizes that the dentist must not only authorize the procedure but also oversee it in real-time. The presence of the dentist allows for immediate interaction, guidance, and intervention if necessary, ensuring that patient safety and care standards are upheld.

In contrast, the other definitions do not meet the criteria for direct supervision. For example, just being available via phone does not allow for immediate oversight and interaction, which is crucial for this supervision level. Similarly, requiring only a review of the procedure after it’s completed falls short of ensuring that the dentist is involved during the actual performance of the procedure. Lastly, having the dentist be absent with only prior consent does not satisfy the supervision requirement, as it lacks ongoing oversight during the treatment, which is a fundamental aspect of direct supervision.
