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

The duties chapter distinguishes an unregistered dental assistant working directly for a dentist, a qualified dental assistant-limited radiology registrant, a qualified dental assistant, and a registered dental assistant, each with its own list of delegable duties and supervision level.

A registered dental assistant, or in some cases a registered dental hygienist, may also apply for expanded-duties permits: a restorative care permit, and class I or class II dental anesthesia assistant permits.

To become a registered dental assistant, qualified dental assistant, or qualified dental assistant-limited radiology registrant, an applicant completes a notarized application with the fee, meets tier-specific education or certification and training-hour requirements, passes a written examination on North Dakota's dental laws and rules, completes a CPR course, and has no grounds for denial under North Dakota Century Code section 43-20-05.

An unregistered dental assistant is not required to register but may only perform the more limited duties the rule lists for that tier.

Every duty in the chapter is delegated under a supervision level: direct, indirect, or general supervision for standard duties, and contiguous or direct visual supervision for the dental anesthesia assistant permits.

The chapter uses these terms throughout but does not itself define what any of them mean.

Confirm the definitions and which level governs a specific duty with the North Dakota Board of Dental Examiners before relying on them.

Under direct supervision, an unregistered dental assistant may take vital signs and preliminary history, apply limited topical medications, take study-cast impressions, hold curing lights, and monitor a nitrous-oxide patient if trained; general supervision covers oral hygiene instruction.

A qualified dental assistant adds acid-etching enamel and relaying an authorized prescription under direct supervision, coronal polishing and indirect orthodontic bonding under indirect supervision, and a longer general-supervision list including dental radiographs.

A registered dental assistant adds face-bow transfers, adjusting permanent crowns outside the mouth, and administering emergency medications under direct supervision; placing and removing rubber dams and monitoring nitrous-oxide patients under indirect supervision; and an extensive general-supervision list covering pit-and-fissure sealants with a board-approved course, final impressions, and dental radiographs.

Taking dental radiographs appears as a single delegable duty under general supervision for a qualified dental assistant-limited radiology registrant, a qualified dental assistant, and a registered dental assistant.

The registration rule additionally requires the limited radiology registrant to hold a radiation health and safety certificate or an equivalent board-approved course, plus a CPR course.

The prohibited-services rule bars any dental assistant from diagnosis and treatment planning, surgery on hard or soft tissue, adjusting a dentist-cemented crown, activating orthodontic appliances or taking orthodontic impressions for a non-patient, and cementing or bonding orthodontic bands or brackets a dentist did not place.

It also bars placing bases or cavity liners, scaling, root planing, or gingival curettage, probing the gingival sulcus, and using a high-speed handpiece in the mouth without an expanded-duties permit.

Administering or titrating local anesthetics, sedation, or general anesthesia drugs is barred without a board-authorized permit, as is monitoring a patient in moderate sedation, deep sedation, or general anesthesia unless the assistant is a trained sedation staff member or anesthesia-permit holder.

An unregistered dental assistant may monitor a patient already induced into nitrous oxide analgesia if the dentist has documented sufficient post-2024 training, and a registered dental assistant may do the same under indirect supervision.

A registered dental assistant or registered dental hygienist holding the right permit may also administer nitrous oxide to a patient who has not taken sedative medication beforehand.

Class I and class II dental anesthesia assistant permits, granted to applicants who complete board-approved training, national certification or examination, and CPR, ACLS, or PALS certification, authorize IV line duties, medication delivery on verbal command, and emergency response under a sedation-permitted dentist's contiguous or direct visual supervision.

Outside a permit, monitoring a patient in moderate sedation, deep sedation, or general anesthesia is prohibited.

Dental assistants need sixteen hours of continuing education every two-year cycle, with no more than eight hours from self-study.

The sixteen hours must include two hours of ethics or jurisprudence, satisfied by passing the laws-and-rules exam, and two hours of infection control, plus a CPR course.

Assistants holding a dental anesthesia assistant permit need at least two more hours on sedation or anesthesia, and restorative permitholders need two hours on restorative dentistry; qualified dental assistant-limited radiology registrants have a shorter, infection-control-and-CPR requirement.

All dental assistants registered with the board must hold a current CPR certificate, and the board may audit an assistant's continuing education credits.
