Oregon Dental Spore Testing Requirements (2026 Guide)
Are Oregon Dental Offices Required to Perform Spore Testing?
Yes — and Oregon is one of the few states in this guide that states the requirement in exact numeric terms rather than by CDC incorporation alone. Under OAR 818-012-0040(2), “heat sterilizing devices shall be tested for proper function by means of a biological monitoring system that indicates micro-organisms kill each calendar week in which scheduled patients are treated.” Testing results must be retained for the current calendar year and the two preceding calendar years — a 3-year window.
What makes Oregon’s rule distinct is its condition: testing is required every calendar week in which scheduled patients are treated, not simply every calendar week regardless of whether the office was open. In practice, any office running a normal patient schedule will still test weekly, but the rule’s phrasing ties the obligation directly to weeks of active patient care rather than the calendar alone.
This guide covers what OAR 818-012-0040 requires in full, how noncompliance connects to Oregon’s “unacceptable patient care” and unprofessional conduct rules, what to do if a spore test fails, and how Oregon OSHA adds a second layer of enforcement.

The Oregon Regulatory Framework for Dental Spore Testing
OAR 818-012-0040 — Infection Control Guidelines
Oregon’s infection control rule opens by noting that in determining what constitutes unacceptable patient care with respect to infection control, the Board may consider current guidelines such as those of the CDC and the American Dental Association. It then lists specific mandatory practices — glove use, PPE, between-patient sterilization, surface disinfection, and sharps disposal — before stating the spore testing requirement directly in subsection (2): biological monitoring of every heat sterilizer each calendar week in which scheduled patients are treated, with results kept for three years. Because the numeric interval and retention period are written directly into Oregon’s own administrative code, Oregon doesn’t rely solely on CDC incorporation the way several other states in this guide do.
Connection to Unacceptable Patient Care and Unprofessional Conduct
OAR 818-012-0040 sits within the same division as OAR 818-012-0010 (Unacceptable Patient Care) and OAR 818-012-0030 (Unprofessional Conduct). A failure to perform or document the required weekly spore testing can be treated as unacceptable patient care with respect to infection control, giving the Board a direct path to discipline under ORS 679.140, which sets out the grounds, procedure, and sanctions for licensee discipline in Oregon.
Oregon OSHA — A State-Run OSHA Program
Oregon operates its own OSHA-approved state plan, Oregon OSHA, administered within the Department of Consumer and Business Services (DCBS). Oregon OSHA enforces workplace safety standards — including the Bloodborne Pathogens Standard — independently of the Board of Dentistry’s infection control rules, giving Oregon dental offices two separate points of regulatory contact.
What Oregon Dental Offices Must Do
1. Test Every Heat Sterilizer Weekly in Patient-Treatment Weeks
Run a biological monitoring test on every heat sterilizing device each calendar week in which scheduled patients are treated, per OAR 818-012-0040(2).
2. Retain Results for Three Years
Keep spore testing results for the current calendar year and the two preceding calendar years.
3. Follow the Full Set of Infection Control Practices
Wear gloves and appropriate PPE, sterilize instruments between patients, disinfect contaminated surfaces with a mycobactericidal germicide, and dispose of contaminated waste and sharps per governmental requirements.
4. Document Every Test
Keep dated records of every spore test and its result, ready for review if the Board evaluates a patient care or infection control complaint.
5. Layer in Mechanical and Chemical Indicators
Use a chemical indicator inside every instrument package and monitor time, temperature, and pressure for every load, consistent with CDC guidance the Board may also consider.
6. Maintain Bloodborne Pathogens Compliance with Oregon OSHA
Keep exposure control plans and Bloodborne Pathogens training current for Oregon’s own state OSHA program.
What to Do If a Spore Test Fails in Oregon
- Remove the sterilizer from service immediately
- Review loading technique, indicator expiration, and cycle settings for cause
- Retest, or have the unit serviced and retested, before returning it to use
- Document the failure, the corrective action, and the retest result in the 3-year testing record required by OAR 818-012-0040(2)

Who Enforces Spore Testing Requirements in Oregon?
1. Oregon Board of Dentistry
Administers OAR 818-012-0040 and can pursue license discipline under ORS 679.140 for infection control failures treated as unacceptable patient care or unprofessional conduct.
2. Oregon OSHA
Enforces the Bloodborne Pathogens Standard and related workplace safety requirements through Oregon’s own OSHA-approved state plan, administered by the Department of Consumer and Business Services, independent of Board licensure action.
Oregon Spore Testing Compliance Checklist
✅ Biological spore testing performed on every heat sterilizer each week scheduled patients are treated
✅ Matching control indicator run from the same lot
✅ Chemical indicator used inside every instrument package
✅ Mechanical monitoring (time/temperature/pressure) recorded for every load
✅ Dated spore testing log maintained for 3 years (current year + 2 preceding)
✅ Gloves, masks, and protective eyewear used per OAR 818-012-0040(1)
✅ Instruments sterilized between every patient use
✅ Bloodborne Pathogens Standard compliance maintained for Oregon OSHA
How Often Should Oregon Dental Offices Test?
Oregon’s rule states the interval directly: every calendar week in which scheduled patients are treated. For a practice running a normal weekly schedule, this means weekly testing on every heat sterilizer, with results kept on file for three years.

Frequently Asked Questions: Oregon Dental Spore Testing
Does Oregon law require weekly biological spore testing?
Yes, with a specific condition: OAR 818-012-0040(2) requires testing each calendar week in which scheduled patients are treated, rather than every calendar week regardless of whether the office saw patients.
How long must Oregon dental offices keep spore testing records?
Three years — the current calendar year plus the two preceding calendar years.
What happens if an Oregon dental office doesn’t perform spore testing?
A failure to meet OAR 818-012-0040’s testing requirement can be treated as unacceptable patient care with respect to infection control, supporting Board of Dentistry discipline under ORS 679.140.
Does Oregon have its own OSHA program?
Yes. Oregon operates its own OSHA-approved state plan, Oregon OSHA, administered by the Department of Consumer and Business Services.
Does Oregon’s infection control rule cover more than spore testing?
Yes. OAR 818-012-0040 also requires glove use, masks and protective eyewear, between-patient sterilization, surface disinfection with a mycobactericidal germicide, and proper disposal of contaminated waste and sharps.
