California Dental Sterilization Compliance Requirements

Biological monitoring (spore testing)

Proper functioning of the sterilization cycle of all sterilization devices shall be verified at least weekly through the use of a biological indicator (such as a spore test).

Worth flagging: Most-cited primary citation in the country. Heavy DBC enforcement footprint. A 2025 proposed amendment was circulated; verify final adopted text before relying on this entry.

Federal guidance applied in California

Standards align with CDC 2003 / 2016

Even where state rules are silent on a specific point, the CDC's 2003 Guidelines for Infection Control in Dental Health-Care Settings are treated as the de facto standard of care by every US state board. Boards routinely cite practices for "unprofessional conduct" when CDC standards are not followed.

What you should keep on file

• •A weekly (or per-state-cadence) biological-indicator log with matching control results, lot numbers, and expiration dates
• •A per-cycle log identifying sterilizer, operator, load contents, and chemical-indicator result
• •Documented response to any positive spore test (recall procedure, retest result, root cause)
• •Sterilizer maintenance and service records (preventive maintenance + repair)
• •A list of staff authorized to operate sterilizers, with training completion dates
• •A written infection-control plan referencing CDC 2003 guidelines
