The Dentist Steps Out Mid-Appointment
Kim is an LDH in a two-chair practice. At 2:10 p.m. Dr. Okafor leaves for a 50-minute off-site consultation. In chair one, Mr. H, 44, received an inferior alveolar block 15 minutes ago; Kim is halfway through scaling and root planing of the upper right quadrant and the block is already fading - he winces when she reaches the distobuccal line angle. In chair two, a 16-year-old new patient is scheduled at 3:00 with her mother for a prophylaxis and sealants; no dentist has ever examined her and there are no radiographs. In chair three at 3:30, Mrs. L, a recall patient examined nine months ago, is booked for prophylaxis and fluoride. The receptionist also asks Kim to call in a chlorhexidine rinse prescription for a patient who phoned with bleeding gums. Kim's local anesthesia certificate is current.
1. Can Kim give Mr. H a second cartridge while Dr. Okafor is off site? What are her options for finishing the quadrant?
Read the worked answer
No. Administering local anesthesia requires direct supervision, meaning the dentist is on the premises, has authorized the procedure, and is immediately available if something goes wrong. A phone call does not satisfy that, and Dr. Okafor is nearly an hour away. The same rule governs re-dosing, not just the first cartridge: a current certificate authorizes Kim to give anesthesia only inside the required supervision level. Her options are to stop at a comfortable point, explain the situation to Mr. H, and reschedule the remainder, or, if he can tolerate it, finish with topical anesthetic and careful instrumentation. She should not push through a painful quadrant to protect the schedule. She should document the time, the anesthetic already given, the reason for stopping, and the plan. If Mr. H developed an urgent problem she would call Dr. Okafor and follow the office emergency protocol, but that does not convert the visit into direct supervision for elective anesthesia.
2. Can Kim start the 16-year-old's prophylaxis and sealants at 3:00 before the dentist returns?
Read the worked answer
This is the harder judgment, and the answer is no for treatment. Prophylaxis and sealants are hygiene services delivered under general supervision, which requires that a dentist has examined the patient and authorized the services; the dentist need not be present during the appointment itself. Nothing in this record shows an examination or an authorization. Sealants in particular require a diagnosis of caries risk and a decision about which teeth to seal - that is the dentist's call. Kim may greet the patient, take a health history, provide assessment and education, and take radiographs if the office protocol and a dentist's order permit, but she should not scale or seal. The practical fix is to swap the schedule, see Mrs. L at 3:00, and either have Dr. Okafor examine the teenager when he returns or reschedule. The front desk should be told why, so the mother hears one consistent explanation rather than three.
3. Mrs. L's appointment and the prescription request: what supervision level applies, and what should Kim do?
Read the worked answer
Mrs. L is a recall patient examined nine months ago and, assuming the dentist authorized recall hygiene services, her prophylaxis and fluoride fall under general supervision: Kim can treat her without the dentist in the building, but the record must show who examined the patient, when, and what was authorized. Kim should update the health history, record blood pressure, complete periodontal charting, and flag anything that needs the dentist's attention. The prescription is a different matter. Prescribing is not a dental hygiene function; calling in a chlorhexidine order would be practicing outside the license even for a long-standing patient. The correct response is to take a message, describe the findings to Dr. Okafor, and let him decide whether to prescribe. If the patient needs to be seen, the front desk should schedule an examination. Documenting the request and the referral protects the patient and the practice.
