Arkansas puts its dental board inside the Department of Health, which is also where the x-ray program lives. That is convenient for finding things and misleading if you assume one registration covers the other. Your license renews on a January cycle set by statute. Your x-ray registration renews every December on the radiation program's cycle. And the radiation rules give you ten days, not thirty, to report almost any change involving a machine.
Key takeaways
- Under Arkansas Code 17-82-310(a)(1), every dentist and dental hygienist renews on January 1 of even-numbered years. Failure to renew within 30 days after January 1 forfeits the license under 17-82-311.
- X-ray machines must be registered within 30 days of acquisition on RC Form 200, with a designated radiation safety officer whose qualifications go to the Department for approval. Each separate physical location needs its own registration form and number.
- X-ray registration renews during December of each year for the following year, and changes (name, address, machine location, RSO, acquisition or disposal, storage status) must be reported in writing within 10 days on RC Form 201.
- Transfers and disposals require written notice within 10 days, including a record of the disposal and, if transferred, to whom. That is a seller obligation, not just a buyer obligation.
Rules change, so verify before acting. Everything below was checked against an official Arkansas or federal source in September 2026. The board's rules document was too large for us to open in full, so several items sit in the "could not confirm" list rather than being guessed at. Confirm with the agency before you act.

License renewal and continuing education
The Dental Practice Act sets the renewal clock in statute. Section 17-82-310(a)(1) requires every dentist and dental hygienist to renew on January 1 of even-numbered years. Section 17-82-311 sets the consequence: failure to renew within a period of thirty days after January 1 forfeits the license. A biennial cycle pegged to a calendar date means the whole state renews at once, which in turn means the board's phones are busy in late December. Do not leave it to the last week.
Continuing education is set in the board's rules rather than in the statute. Arkansas has a dedicated CE article in its rules and runs a CE capture portal for reporting hours, separate from the license renewal portal. We were not able to open the current rules document in full during research, so we are not going to state an hour total we did not read. Pull the CE article from the board's rules PDF, or call the board at the number on its page, before you plan a CE budget.
One structural note worth knowing from the Practice Act: section 17-82-104(c) makes it unlawful for any corporation to practice dentistry or dental hygiene or to hold itself out as entitled to do so, while section 17-82-104(a)(1)(A) permits a dentist to practice under a corporate name that complies with the Dental Corporation Act at Arkansas Code 4-29-401 and following. If you are structuring an entity, a management arrangement or a partial sale, that pair of provisions is the first thing your attorney should read.
X-ray equipment: registration and inspection
The Arkansas Department of Health X-Ray Program handles registration, and it publishes unusually clear mechanics.
- Who registers: any person with physical possession or control of a radiation machine capable of producing radiation in Arkansas, within 30 days of acquisition.
- How: RC Form 200, the radiation machine facility registration, with the applicable fee. Each separate physical location requires its own form and gets its own registration number.
- Radiation safety officer: a designated RSO is required, and the RSO's qualifications are submitted to the Department for approval. This is not a name you write on a form and forget.
- Renewal: during December of each year for the following year, as long as the activity requiring registration continues.
- Changes: reported in writing within 10 days using RC Form 201, the registration change request. The list includes registrant name or address, machine location, RSO designation, machine acquisition or disposal, and storage status.
- Advance authorization: some uses require Department authorization before operation, including healing arts screening, therapeutic radiation machines under 500 kV, electronic brachytherapy, and radiation therapy simulation systems.
The program's FAQ adds the practice-level rules an inspector will ask about. Facilities must monitor employees likely to receive more than 500 mrem annually, and exposure records are kept for at least the duration of employment plus 30 years. Patient radiographs should be retained for five years, with joint replacement films kept ten years and minors' images kept until age 18. Someone must be designated as responsible for safe practices and employee training. Mechanical holding devices are preferred over human holders. Lead shielding of at least 0.5 mm is expected for patients of reproductive age when the gonads are in the beam. On inspections, the program says state inspectors contact facilities on a predetermined schedule and that registrants should have current registration, employee notices, dosimetry records and radiation safety documentation available.
Build a single binder or shared folder holding the RC Form 200 registration, the RSO approval, dosimetry records, the employee notice posting, and your last inspection report with any corrective action. That is the stack an Arkansas inspector asks for, and assembling it the morning of an inspection never goes well.
Who may take radiographs
We could not confirm from an official Arkansas source whether a dental assistant needs a specific state radiology credential before exposing radiographs, or what training the board requires. The board registers dental assistants and publishes application pathways, so ask the board directly which registration or permit covers radiography before you assign it to a new hire.
For general mechanics, see dental x-ray registration and inspections and the equipment guides on intraoral x-ray units and panoramic units.
Buying and selling used equipment in Arkansas
The ten-day clock runs on both ends
Buy a used pan and you have 30 days from acquisition to register it, and a 10-day change request if it is being added to an existing registration. Sell or scrap a machine and you have 10 days to file written notice including a record of the disposal and, if transferred, to whom it was transferred. Sellers who skip that step stay on the books for equipment they no longer own and keep paying for it every December.
Reconcile before closing
In a practice purchase, ask for the current RC Form 200 registration, the machine list attached to it, and the name of the approved RSO. Then walk the operatories. A registration listing a machine that left years ago, or naming an RSO who retired, is a cheap early signal about the rest of the compliance file. Our practice acquisition due diligence checklist has the wider list.
Moving or opening a second location
Each separate physical location needs its own registration and number, so a satellite office is a new RC Form 200 rather than an amendment. A relocation is a change of machine location, which is a 10-day filing. See moving a dental office.
Amalgam separators and wastewater
Arkansas does not publish a separate state separator rule. The federal EPA dental rule at 40 CFR Part 441 applies if you place or remove amalgam and discharge to a publicly owned treatment works: a compliant separator, best management practices (no flushing scrap amalgam, no oxidizing line cleaners), and a one-time compliance report filed with your pretreatment control authority, typically the municipal water utility. Ask the utility what it wants from an incoming owner at closing. See amalgam separators and dental waste disposal.
Before you commit on any used unit, run the pre-purchase equipment checklist and read the hidden costs of buying used equipment.
Non-competes and employment
Arkansas has a statute governing covenants not to compete, and it has been amended in the past decade in ways that changed how courts handle overbroad restrictions. We were not able to open the codified text from an official Arkansas source during research, so we are not going to summarize its terms secondhand.
What to do instead: hand your agreement to an Arkansas employment attorney with three specific questions. Does the statute require the employer to show a protectable business interest, and what counts as one for a dental practice? If the duration or geography is too broad, will a court reform the covenant to something reasonable or refuse to enforce it at all? And does the covenant survive if the practice terminates the associate rather than the associate leaving? Those three answers determine whether a restrictive covenant in an Arkansas associate contract is a real constraint or a bluff.
At the federal level, the FTC's non-compete rule is not in effect. The Commission voted on September 5, 2025 to dismiss its appeals and accede to the vacatur, so state law governs. See our national overview of non-compete agreements for dentists and the associate contract red flags guide.
What we could not confirm
- Arkansas continuing education hour totals for dentists and dental hygienists. The board's rules document was too large for us to open; read the continuing education article in the ASBDE rules directly.
- The x-ray registration fee amounts. The Department references a fee schedule PDF but the dollar figures were not on the registration page we read.
- How often Arkansas inspects dental x-ray facilities. The FAQ says inspectors work from a predetermined schedule but does not publish an interval.
- Whether a dental assistant needs a specific Arkansas radiology credential before exposing radiographs.
- The codified text of Arkansas's non-compete statute.
- Sales and use tax treatment of dental equipment, including private-party purchases. Confirm with the Arkansas Department of Finance and Administration and your CPA.
- How the corporate practice provisions in 17-82-104 apply to management services arrangements and DSO structures. That is a question for a dental-specific attorney.
Where to verify

- Arkansas Department of Health: Dental Practice Act and board rules
- Arkansas X-Ray Program: program home, registration information, and X-ray FAQs
- US Environmental Protection Agency: dental effluent guidelines, 40 CFR Part 441
- Federal Trade Commission: September 2025 statement on the non-compete rule
Putting it to work
Two dates run an Arkansas practice's compliance year: December, when the x-ray registration renews for the following year, and January 1 of even-numbered years, when licenses renew. Between them, keep a standing 10-day trigger for any machine acquired, disposed of, moved or put into storage, and for any change of RSO or address. If you are buying a practice, reconcile the registered machine list to the building before closing and confirm who files the change request.
