Dental Assistant Requirements in Utah: Registration, X-Ray Rules & Allowed Duties

Utah's practice act defines only one title, 'dental assistant,' as an unlicensed individual who performs supervised acts and duties the division sets by rule.

On top of that base role, the division issues two expanded-function certifications a dental assistant can earn: one to place, condense, carve and polish direct restorations, and one to remove coronal dental adhesive.

Both certifications require completing an approved education program and passing an exam, and both are performed under a dentist's indirect supervision.

The statute treats a dental assistant as an unlicensed individual, and the source names no application, registration or licensing process for that base role.

The two expanded-function certifications are different: an applicant needs either a current dental hygienist license or at least 3,500 hours of dental assisting in the last six years plus current CPR or BCLS-BLS certification, an approved education program, and a passing score on a Division-approved exam with a written and a clinical component.

The practice act defines three supervision levels.

Direct supervision means the supervising dentist is present and available for face-to-face communication where the service is provided.

General supervision means the dentist is available for consultation but need not be on the same premises.

Indirect supervision means the dentist is present in the facility and available for immediate face-to-face communication.

The source ties a certified expanded-function dental assistant's work to a dentist's indirect supervision, while a dental assistant still training toward that certification must work under the dentist's direct supervision.

The source does not state a single supervision level that covers every routine dental assistant duty; specific duties, like initiating nitrous oxide, carry their own supervision rule.

Utah's rule works by listing what a dental assistant may not do rather than an affirmative duties list, so anything not on that list, and not otherwise reserved to a licensed provider, remains open to a supervised dental assistant.

The rule confirms specific allowed acts: coronally polishing teeth with a rubber cup, exposing radiographs once qualified, and assisting with nitrous oxide analgesia under a dentist's direct supervision after the dentist sets the baseline.

A dental assistant with the direct-restorations certification may place, condense, carve or polish restorative materials on a direct restoration and use a hand instrument or slow-speed handpiece on it; one with the coronal-adhesive certification may remove coronal dental adhesive the same way, both under the parameters and consent the rule sets.

A dental assistant may not initially introduce nitrous oxide analgesia and oxygen to set a patient's safe plane of analgesia unless a licensed dentist who holds the appropriate sedation permit is directly supervising and has already established and documented the baseline percentage and flow rate.

Separately, for a patient under any level of sedation, including nitrous oxide, the rule treats it as unprofessional conduct to fail to provide continuous in-operatory observation by a trained dental patient care staff member until the patient can maintain their own airway and may be safely discharged, or to fail to record the discharge time and who discharged the patient.

The source names no continuing education requirement for the base dental assistant title.

A dental assistant who holds a certification does have a CPE cycle: every two years, a dental assistant certified for the placement of direct restorations must complete at least three hours of didactic CPE specific to that function, and a dental assistant certified for the removal of coronal dental adhesive must complete at least one hour of CPE related to that function, on the same two-year renewal cycle as a Utah dental license or permit.
