Supervision Levels and Delegation of Clinical Procedures
Supervision levels define the degree of dentist oversight required when delegating tasks. Alabama recognizes direct, indirect, general, and public health supervision. Direct supervision means the dentist is physically present in the office and personally evaluates the patient before and after the procedure. Indirect supervision means the dentist is in the office but not necessarily present in the treatment room; the dentist must have authorized the procedure and be available for consultation. General supervision means the dentist has authorized the procedure but is not physically present; the hygienist or assistant may perform the task independently, often in settings like schools or nursing homes. Public health supervision allows hygienists to practice in certain public health settings without a dentist on-site, under specific conditions. Traps include mixing up indirect and general supervision, or assuming a task allowed under direct supervision can be done under general. Rule of thumb: the more irreversible or risky the procedure, the stricter the supervision required. For example, administration of local anesthesia by a hygienist requires direct supervision. Taking radiographs may require direct or indirect supervision depending on the rule. Delegation is only permitted for tasks the delegate is trained and authorized to perform. The dentist is responsible for the delegate's actions. Example: A hygienist performing a prophylaxis under general supervision in a school program must have a written protocol and the dentist must have examined the patient within a specified timeframe. Candidates should know that supervision levels are defined in Board rules and that violating them is grounds for discipline. Always verify the current supervision level for a given procedure, as rules can change. Understanding these levels ensures patient safety and legal compliance.
