Dental Assistant Requirements in Idaho: Registration, X-Ray Rules & Allowed Duties
Idaho's dental rules regulate dentists, dental hygienists, and dental therapists as licensees, and do not license or register dental assistants.
Practice Standards Section 200.03 simply authorizes a dental assistant to perform dental services for which they are trained, unless the rule prohibits the duty, under a dentist's direct supervision for intraoral procedures.
The chapter lists specific prohibited duties, names dental assistants in its infection-control and nitrous oxide provisions, and does not mention radiography, x-rays, or continuing education for assistants anywhere in its text.

The Short Version
- Registration or licensure
- Section 001 sets the rules as the minimum requirements for licensure and regulation of dentists, dental hygienists, and dental therapists only; dental assistants are not named as a licensed or regulated profession under this chapter, and it sets out no registration or licensure process for them.
- Taking x-rays
- The chapter does not mention radiography, x-rays, or any radiography permit for dental assistants anywhere in its text; the reviewer confirmed this by a full-text search, so anyone hiring or working as a dental assistant in Idaho should confirm any x-ray expectations directly with the Idaho State Board of Dentistry.
Idaho defines no separate dental assistant credential
The chapter's scope covers licensure and regulation of dentists, dental hygienists, and dental therapists; dental assistants are not one of the professions it licenses.
Practice Standards Section 200.03 refers to "dental assistants" as a single, undifferentiated category, and the rule creates no tiers, registration levels, or expanded-function titles within that category.
The rules constitute the minimum requirements for licensure and regulation of dentists, dental hygienists, and dental therapists.
Does a dental assistant have to register in Idaho?
The chapter's scope statement limits the rules' licensure and regulation requirements to dentists, dental hygienists, and dental therapists.
Dental assistants are not listed among the professions the Board licenses or registers under this chapter, and no separate section anywhere in the rules sets out an application, exam, or fee for an individual dental assistant.
The rules constitute the minimum requirements for licensure and regulation of dentists, dental hygienists, and dental therapists.
What direct supervision means for a dental assistant
The rule requires a dental assistant to be directly supervised by a dentist when performing intraoral procedures, with one exception: providing palliative care as directed by the supervising dentist.
The chapter has no separate definitions section (Sections 004-099 are reserved), so it does not further define "direct supervision" beyond this requirement.
What a dental assistant is authorized to do
A dental assistant is authorized to perform dental services for which they are trained, unless a duty is prohibited by the rules.
Section 200.09 adds that dental assistants, like licensees, must comply with current CDC infection-control guidelines covering personal protective equipment, instrument sterilization, sterilizing-device testing, disinfection of contact surfaces, and contaminated-waste disposal.
Dental assistants are authorized to perform dental services for which they are trained unless prohibited by these rules.

A dental assistant is prohibited from performing the following duties:
Nitrous oxide and sedation
Persons licensed to practice and dental assistants trained in accordance with the rules may administer nitrous oxide/oxygen to patients, and the dental office must have a fail-safe delivery system, a scavenging system, and a positive-pressure oxygen delivery system.
Administering any other sedation or a local injectable anesthetic is on the dental assistant's prohibited-duties list.
Persons licensed to practice and dental assistants trained in accordance with these rules may administer nitrous oxide/oxygen to patients.
Infection control
Licensees and dental assistants alike must comply with current CDC infection-control guidelines covering personal protective equipment, instrument sterilization, sterilizing-device testing, disinfection of non-critical and clinical contact surfaces, and contaminated-waste disposal.
Heat-sterilizing devices must be tested each calendar week patients are treated, with results retained for the current year and the two preceding calendar years.

Yes, for intraoral procedures.
