Dental Hygienist Requirements in Hawaii: Scope of Practice & Direct Access
Dental Hygienists in Hawaii are regulated by the Hawaii State Board of Dental Examiners. The ADHA's direct-access chart does not list a provision for Hawaii; that absence is the fact on record, not a statement about what dental hygienists may or may not do there.

What a Dental Hygienist Can Do in Hawaii: Permitted Functions & Supervision Levels
Hawaii's ADHA chart pattern is a two-level split for most functions rather than a single supervision level.
Eleven of the 22 functions — oral prophylaxis, x-rays, topical anesthesia, fluoride, sealants, scaling and root planing, soft tissue curettage, study cast impressions, placing and removing periodontal dressings, and removing sutures — carry a D/G cell, meaning direct supervision in one setting and general supervision in another.
Local anesthesia stands apart at direct supervision alone, with no general-supervision alternative, and dental hygiene assessment sits at general supervision alone.
Administering nitrous oxide, placing sutures, dental hygiene diagnosis, treatment planning, prescriptive authority, Botox, lasers, vaccines and dermal fillers are not listed on the chart for Hawaii.
- Eleven of the 22 functions carry a D/G cell for Hawaii, meaning the supervision level depends on the setting: direct supervision in one, general supervision in the other.
- Local anesthesia is listed at direct supervision (D) only, without the general-supervision alternative that most other listed Hawaii functions carry.
- Dental hygiene assessment is the single function listed at general supervision (G) alone.
- Nine functions — administering nitrous oxide, placing sutures, dental hygiene diagnosis, treatment planning, prescriptive authority, Botox, lasers, vaccines and dermal fillers — are not listed on the chart for Hawaii.
- D
- Direct supervision: dentist needs to be present
- G
- General supervision: dentist needs to authorize prior to services, but need not be present

Local Anesthesia by Dental Hygienists in Hawaii
Hawaii authorized hygienists to administer local anesthesia in 1987 by statute.
The ADHA chart lists direct supervision — meaning the dentist must be present — for both block and infiltration injections, education from an accredited program, and an exam given by the course.
The course requirement it records is 39 hours of didactic and clinical instruction plus 50 injections.
Confirm the current course and permit rules with the Hawaii State Board of Dental Examiners before enrolling or applying.

Silver Diamine Fluoride by Dental Hygienists in Hawaii
Hawaii's ADHA entry names SDF directly rather than folding it under a general fluoride provision.
The scope-of-practice provision, Title 25 §447-3, permits dental hygienists to apply preventive chemical agents to the coronal surfaces of the teeth, provided the board of dentistry has approved the specific agent.
ADHA quotes board meeting minutes from January 23, 2017 affirming that SDF is a preventive chemical agent a dental hygienist can apply.
ADHA lists supervision as General, meaning a dentist authorizes the application in advance without needing to be present.
The provision states no separate training, course, or permit requirement beyond the board's approval of the agent itself.
Dental hygienists may apply preventive chemical agents to the coronal surfaces of the teeth, which chemical agents have been approved by the board of dentistry. Board meeting minutes affirm “that SDF is a preventive chemical agent that can be applied by a dental hygienist.”

What Direct Access Does — and Doesn’t — Cover
Direct access is one dimension of scope, not scope itself. The ADHA’s direct-access chart records whether a dental hygienist can initiate treatment and treat a patient without a dentist present — the function-by-function supervision levels and the local anesthesia rules above come from two separate ADHA charts, and the three do not always line up neatly.
Don’t generalize from a direct-access provision to any other part of scope, and confirm specifics with the Hawaii State Board of Dental Examiners.
Frequently Asked Questions
Does a dentist have to supervise a dental hygienist in Hawaii?
The ADHA's direct-access chart does not record a provision for Hawaii.
That absence is the fact on record — it is not a statement that dental hygienists cannot practice there.
Confirm supervision requirements with the Hawaii State Board of Dental Examiners.
Who regulates dental hygienists in Hawaii?
Dental Hygienists in Hawaii are regulated by the Hawaii State Board of Dental Examiners.
Scope of practice is set by state law and changes over time, so verify current rules directly with the board before relying on them.
Can a dental hygienist in Hawaii give local anesthesia without a dentist present?
No. The ADHA Practice Act chart lists local anesthesia in Hawaii at direct supervision (D) only, meaning the dentist must be present while it is administered.
The Local Anesthesia chart agrees, listing direct supervision since 1987 for both block and infiltration, an exam given by the course, and a course of 39 hours didactic and clinical instruction plus 50 injections.
That is a single, stricter level than the D/G split most other Hawaii hygiene functions carry, so confirm current requirements with the Hawaii State Board of Dental Examiners.
Which hygiene functions in Hawaii require the dentist to be in the room?
Eleven functions on the ADHA chart carry a D/G cell for Hawaii — oral prophylaxis, x-rays, topical anesthesia, fluoride, sealants, scaling and root planing, soft tissue curettage, study cast impressions, placing and removing periodontal dressings, and removing sutures — meaning each sits at direct supervision in one setting and general supervision in another.
Local anesthesia is listed at direct supervision alone.
The chart does not say which cells carry ADHA's numbered footnotes, so check the Hawaii State Board of Dental Examiners' rules for the setting distinction and any added condition.
Does the Hawaii chart list dental hygiene diagnosis or prescriptive authority?
No. Dental hygiene diagnosis, treatment planning and prescriptive authority are all listed as not listed on the ADHA chart for Hawaii, alongside administering nitrous oxide, placing sutures, Botox, lasers, vaccines and dermal fillers.
Not listed means the function does not appear on the chart at all, a narrower statement than a ban under Hawaii law.
Dental hygiene assessment is the exception among these related functions, listed at general supervision.
For what any of these functions require under Hawaii law, ask the Hawaii State Board of Dental Examiners.
Does Hawaii's dental board require special training before a hygienist applies silver diamine fluoride?
The entry ADHA cites, Title 25 §447-3, only requires that the chemical agent itself be approved by the board of dentistry; it does not state a separate training, course, or permit requirement for the hygienist applying it.
ADHA quotes board meeting minutes from January 23, 2017 affirming that SDF qualifies as a preventive chemical agent hygienists can apply, and lists supervision as General.
Confirm any additional training expectation with the Hawaii State Board of Dental Examiners before applying SDF.
