Expanded Functions When the Hygienist Is Out

Dr. Marcus Ramos staffs a community dental clinic in Indianapolis. His only hygienist is on FMLA leave for six weeks. Two dental assistants are available. Assistant A holds a certificate in coronal polishing; Assistant B was trained on the job and has no expanded-function certificate. The schedule includes a 58-year-old with 6-mm periodontal pockets, bleeding on probing, and radiographs showing horizontal bone loss, booked as a "prophy"; a 15-year-old due for sealants; and a 4-year-old due for fluoride varnish. Dr. Ramos also covers a second clinic 25 minutes away and plans to be there most of the afternoon, reachable by cell phone. He tells Assistant A to "do the scaling and root planing" on the periodontal patient and tells Assistant B to "polish and apply fluoride" to the 4-year-old. A dental assistant asks whether these instructions are within Indiana law.

1. Evaluate both delegations. May Assistant A perform scaling and root planing, and may Assistant B polish and apply fluoride?

Read the worked answer

Assistant A may not perform scaling and root planing. SRP is periodontal therapy that requires a dentist's diagnosis and treatment plan and must be performed by a licensed dentist or dental hygienist; it is not within the dental assistant scope even for an assistant with a coronal-polishing certificate. Assistant B may not polish or apply fluoride without the required expanded-function credential. Even if Assistant B had the certificate, coronal polishing and fluoride application are delegated functions subject to the Board's supervision rules. With Dr. Ramos 25 minutes away and reachable only by phone, the clinic likely cannot satisfy direct supervision, which requires the dentist to be physically present and immediately available. The 4-year-old's age and cooperation also make an on-site dentist prudent. The correct response is to stop both assignments, reschedule or obtain a licensed hygienist, and have Dr. Ramos perform or directly supervise procedures that require his presence.

2. Explain the supervision levels that matter here and what Dr. Ramos must do to bring the schedule into compliance.

Indiana distinguishes direct supervision-dentist on the premises and immediately available-from general supervision-dentist not on the premises but available and having authorized the service under the applicable rules. The key is that phone availability from another clinic is not direct supervision. Dr. Ramos must either remain on-site for functions requiring direct supervision, hire a temporary hygienist, or reschedule those patients. He may perform the SRP himself after his own periodontal examination. Sealants may be delegable to an appropriately trained assistant only if the Board's expanded-function rules and supervision level are satisfied; he should verify the assistant's certificate and the specific rule before proceeding. The periodontal patient needs a real periodontal diagnosis and treatment plan, not a prophy labeled as one. Staff should document who performed each service, under what supervision, and with what consent. If the patient is delayed, the clinic should explain the reason and offer a new appointment rather than let an unqualified assistant proceed.

3. What liability and recordkeeping issues arise from the original instructions if an assistant treats a patient and causes harm?

Read the worked answer

The dentist remains professionally responsible for delegating within scope and for supervising the person to whom care is delegated. If an assistant performs SRP or an expanded function without the required credential or supervision, the dentist faces Board discipline for aiding unlicensed or unauthorized practice, and the practice faces civil exposure for any injury. The patient's consent should identify who will perform the service and the supervision arrangement. The record should include the dentist's examination and diagnosis, the specific procedure, the operator, the supervising dentist's presence or availability, and any complications. A note that simply says "prophy done" is inadequate for a patient with bone loss and bleeding. If harm occurs, the dentist should ensure follow-up, document objectively, and not alter the record. The clinic should also correct its scheduling templates so unbooked SRP is not mistaken for routine hygiene.
