Dental Practice Resources in Indiana

Indiana is one of the cleaner states to research because the two agencies that matter most are easy to tell apart. Licenses come from the Indiana Professional Licensing Agency. Radiation machines and the people who operate them come from the Indiana Department of Health. Where Indiana gets expensive is imaging: the state does not send an inspector, it requires you to hire an approved physicist or machine inspector and pay for the evaluation yourself. That changes the math on used x-ray equipment.

Who regulates what

License renewal and continuing education

Indiana runs a two-year cycle keyed to an unusual date. The Professional Licensing Agency states that dentist and dental hygienist licenses, controlled substance registrations, general anesthesia and deep sedation permits, light parenteral conscious sedation permits and mobile dental practice permits all expire on March 1 of even-numbered years. Renewal notices are sent roughly 90 days before expiration, which means the mail lands in early December of odd years, right when nobody is reading practice mail.

The CE requirements published by the agency:

• Dentists: 20 hours per renewal cycle, with at least half completed in live presentations or live workshops, plus a 2 hour course covering ethics, professional responsibility, and the Indiana statutes and administrative rules.
• Dental hygienists: 19 hours per renewal cycle, again with at least half live, plus a basic life support course and the same 2 hour ethics, professional responsibility and Indiana statutes and rules course.

Two practical notes. First, the live presentation requirement is the one that trips people who bulk-buy online CE in February. Half of it has to be live. Second, the mandatory ethics and jurisprudence course is Indiana-specific, so a national provider's generic ethics course may not satisfy it. Check the course description against the board's language before you buy.

The agency does not issue licenses for dental assistants. That matters for staffing plans, because the credential an assistant needs to take x-rays comes from a different agency entirely, covered below.

X-ray equipment: registration and inspection

The Indiana Department of Health's Division of Radiology, Weights and Measures registers radiation machines. The registration rule requires a facility to register with the board before operating a radiation machine facility, using the department's form, and to designate an individual responsible for radiation protection. That designation is not decorative, it is the name the state will call when something is wrong.

The inspection model is what makes Indiana different from most of its neighbors. The department's guidance to radiation machine facilities states that dental facilities must be evaluated at least once every 36 months, and that the evaluation is performed by a diagnostic imaging physicist or an x-ray machine inspector approved by the department. The cost of that evaluation is negotiated directly between the physicist or inspector and the practitioner. The state does not cover it. The department maintains a published list of approved physicists and inspectors.

On operators: Indiana requires a dental radiographer license, issued by the Department of Health rather than the licensing agency. The department's published requirements include completion of an approved radiography education program, clinical training under an active permit, and passing an approved examination. Graduates of programs accredited by the Commission on Dental Accreditation may be able to use a proficiency certificate in place of some documentation. Hiring an assistant from out of state does not transfer the credential automatically, so build the licensing timeline into your onboarding plan.

Buying and selling used equipment in Indiana

Registration and the evaluation clock

When you bring a used x-ray unit into an Indiana facility, you are changing the machine inventory the state has on file, so update your registration with IDOH using the radiation machine registration application. When you sell or scrap a unit, take it off your registration so you are not carrying it on the books. Registration is tied to the facility, not to the individual machine's history, which means a used machine's paperwork does not travel with it: the receiving facility has to account for it.

Then look at the evaluation calendar. If a used pan or CBCT arrives at your office and its last approved evaluation was 30 months ago, you have six months before it is due, and you are the one hiring the physicist. Ask for the last evaluation report as part of the purchase, the same way you would ask for service records on a compressor.

Amalgam separators and wastewater

The controlling rule is federal. EPA's dental effluent guidelines at 40 CFR Part 441 apply to dental dischargers that place or remove amalgam and discharge to a publicly owned treatment works. The requirements are an amalgam separator that meets the standard, best management practices including not flushing scrap amalgam and not using oxidizing line cleaners, and a one-time compliance report to your pretreatment control authority, which for most Indiana practices is the municipal utility that bills you for sewer service.

Ownership change is the moment to call that utility. EPA's page does not spell out how transfers are handled, and the control authority decides what it wants on file. See our guide to amalgam separators for how the units work and what records to keep.

Lead, chemicals and decommissioning

Old film processors leave behind fixer, developer and lead foil. Lead aprons eventually fail and become waste. None of it goes in the trash. Use a licensed waste vendor and keep manifests. Our dental waste disposal guide covers each stream, and disconnecting dental equipment safely covers the physical removal.

If you are on the selling side, pricing your equipment honestly and choosing a sales channel both go better when your registration and evaluation paperwork is clean.

Non-competes and employment

We could not confirm from an Indiana statute or an official state source that Indiana has a statute governing dentist non-competes specifically. Indiana has enacted restrictions in recent years on non-compete agreements involving physicians, but the Indiana General Assembly's code site would not render for us to verify the scope of that chapter or whether it reaches dentists, so we are not going to characterize it here. Treat that as an open question for counsel.

What you can rely on as a general matter: in a state without a controlling statute, non-competes are judged under common law reasonableness, and courts look at duration, geographic scope, the scope of activity restricted, and whether the employer has a legitimate protectable interest such as patient relationships. An Indiana employment attorney who works with health care employers can tell you where the courts currently draw those lines, and can tell you whether the physician-focused legislation affects your agreement.

One federal point is settled. 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 of the rule, so state law controls. Our national overview of non-compete agreements for dentists explains the common clause structures, and the associate contract red flags piece covers what else to read before signing.

What we could not confirm

• Indiana radiation machine registration fees and whether registration renews annually or on another interval. The department publishes the application form but not a fee schedule we could read.
• Whether Indiana law restricts dentist non-competes, and whether the state's physician-focused non-compete legislation reaches dentists. The General Assembly's code site would not load the chapter text for us.
• Any Indiana-specific infection control rule beyond the board's general practice standards and federal OSHA requirements.
• Sales and use tax treatment of dental equipment, including private-party and out-of-state purchases. Confirm with the Indiana Department of Revenue and your CPA.
• The limits Indiana places on non-dentist ownership of a practice. The board does not publish this clearly, confirm directly with the board and a dental-specific attorney.

Where to verify

• Indiana Professional Licensing Agency: Indiana State Board of Dentistry, renewal information, and dentistry licensing information
• Indiana Department of Health: Radiology, Weights and Measures and the x-ray machine inspection frequency guidance
• Indiana Department of Health: dental radiographer license requirements
• US Environmental Protection Agency: dental effluent guidelines, 40 CFR Part 441
• Federal Trade Commission: September 2025 statement on the non-compete rule
• Indiana Department of Revenue: in.gov/dor

Putting it to work

The Indiana-specific items to put on a transition checklist are short and worth the effort: the current IDOH facility registration with the machine list, the most recent approved evaluation report for every x-ray unit, the dental radiographer licenses for every staff member who exposes films, and the one-time EPA amalgam compliance report filed with the sewer utility. Everything else in an Indiana deal looks like a deal anywhere else.
