# Ohio dental license renewal Answer: For dental license renewal in Ohio, use the official board for filing forms, fees, deadlines, and final instructions. Dentovio summarizes the renewal CE signals: dentists need 30 hours / 2 years (biennial); dental hygienists need 20 hours / 2 years (biennial); dental assistants: Dental X-ray Machine Operator (formerly Dental Assistant Radiographer): 2 hours / 2 years in dental x-ray/radiation technology. EFDAs (Expanded Function Dental Auxiliaries) have NO CE requirement to maintain registration.. Renewal-cycle notes: Biennial cycle; dentists and hygienists renew on the odd/even schedule via the eLicense portal. Radiographers renew by Dec 31 of even years. MANDATORY: current Healthcare-Provider-level BLS/CPR + AED with hands-on skills every renewal (didactic may be online, but the clinical/compressions portion must be in person; Board accepts no substitute certification). NO separately mandated hour minimums for jurisprudence, ethics, or opioid/controlled-substance CE (infection control, pharmacology, etc. are listed as acceptable/permitted subjects, not required). LIVE-vs-SELF-STUDY: all 30 (dentist) and all 20 (hygienist) hours may be completed online or by correspondence — no live minimum. Courses must be from an ADA/CERP- or AGD-PACE-approved sponsor. NOTE: older secondary sources cite '40 hours' for dentists and '24 hours' for hygienists; these are outdated/incorrect — current ORC 4715.141 says 'not less than thirty hours' (dentist) and ORC 4715.25 says 'minimum of twenty hours' (hygienist).
