US dental sterilization compliance requirements, state by state

Every US dental practice has to prove its instruments are actually sterile — and the two questions an inspector always asks are how often you run a spore (biological) test and how long you keep the records. The catch: those answers are set state by state. Most states adopt the CDC standard of at least weekly biological monitoring by reference; a handful — like California, Ohio, Oregon, and Washington — write the interval and the retention period directly into their dental board rules.

Below is every state plus the District of Columbia. Where we've confirmed a state-specific rule against its primary source, it's marked verified with a citation. Where a state simply defers to the CDC, we say so plainly rather than invent a number — because a wrong rule you rely on is worse than no rule at all.
