# Ohio dental hygienist CE requirements > Role-specific continuing education summary for dental hygienists renewing in Ohio. URL: https://dentovio.com/ce-requirements/ohio/dental-hygienist Last verified: 2026-07-08 Research confidence: high Educational summary only, not compliance advice. CE hour counts, approved-provider rules, audit rules, and mandatory topics can change. Confirm current instructions with the Ohio dental board before filing a renewal. ## Direct answer Dental hygienists in Ohio: 20 hours / 2 years (biennial). 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 NOTE: older secondary sources cite '40 hours' for dentists and '24 hours' for hygienists; these are outdated/incorrect — current ORC 4715.141 says 'not less than thirty hours' (dentist) and ORC 4715.25 says 'minimum of twenty hours' (hygienist).
