Nevada Dental Spore Testing Requirements (2026 Guide)
Are Nevada Dental Offices Required to Perform Spore Testing?
Yes — and Nevada backs the requirement with two layers of CDC guidance and one of the most proactive inspection systems in this guide. NAC 631.178 requires every person licensed under Nevada’s dental practice act to comply with both the CDC’s Guidelines for Infection Control in Dental Health-Care Settings-2003 and the CDC’s Guideline for Disinfection and Sterilization in Healthcare Facilities, 2008 — adopting both documents by reference. Because the 2003 CDC guidance calls for weekly biological (spore) testing of every sterilizer, that becomes the practical, Board-enforceable standard for Nevada dental offices.
What sets Nevada apart from most states in this guide is that compliance isn’t just complaint-driven. Under NAC 631.1785, any dentist who becomes the owner of a new dental office or facility in Nevada must request an initial Board inspection within 30 days of taking ownership — and the Board must inspect within 90 days of that request. On top of that, NAC 631.179 gives the Board’s Executive Director standing authority to assign agents to conduct unannounced random inspections of any dental office, independent of any complaint or new-ownership trigger.
This guide covers what NAC 631.178 requires, how Nevada’s mandatory initial-inspection and random-inspection systems work, what to do if a spore test fails, and how Nevada’s own state OSHA plan adds a second layer of enforcement.

The Nevada Regulatory Framework for Dental Spore Testing
NAC 631.178 — Adoption of CDC Guidelines by Reference
Nevada’s dental infection control rule is broader than most: NAC 631.178 requires every licensee to comply with both the CDC’s 2003 Guidelines for Infection Control in Dental Health-Care Settings and the CDC’s 2008 Guideline for Disinfection and Sterilization in Healthcare Facilities. Adopting both documents by reference means Nevada’s sterilization standard draws on the CDC’s more detailed, sterilization-specific 2008 guidance in addition to the general 2003 dental infection control guidelines — a dual-document approach not used by every state. Because the 2003 guidance calls for weekly spore testing of every sterilizer, that interval becomes the operative standard.
Mandatory Initial Inspection for New Offices
NAC 631.1785 requires a licensed dentist who becomes the owner of a new dental office or facility in Nevada to request, in writing, an initial Board inspection within 30 days of taking ownership. The Board then has 90 days to complete that inspection and issue a report on whether the office is equipped in compliance with the guidelines adopted in NAC 631.178. If the office isn’t compliant, the Executive Director issues a written notice identifying critical deficiencies, followed by a reinspection process. This means every new Nevada dental office is subject to a proactive, guaranteed infection control inspection — not just an inspection triggered by a complaint.
Random Inspections — No Notice Required
NAC 631.179 separately authorizes the Executive Director to assign agents to conduct random inspections of any dental office in the state, at any time, without advance notice to the dentist. These inspections exist independently of the new-owner inspection process and can happen to any established Nevada dental practice. The Board follows the same reporting and reinspection process as the new-owner inspections, including potential cease-and-desist orders for personnel not in compliance.
Nevada OSHA (NVOSHA) — A State-Run OSHA Program
Nevada operates its own OSHA-approved state plan, Nevada OSHA (NVOSHA), which enforces standards equivalent to — and in some cases more stringent than — federal OSHA standards, including the Bloodborne Pathogens Standard. NVOSHA compliance officers inspect workplaces independently of the Board of Dental Examiners’ infection control inspections, giving Nevada dental offices dual regulatory exposure.
What Nevada Dental Offices Must Do
1. Follow Both CDC Guideline Documents
NAC 631.178 requires compliance with the CDC’s 2003 infection control guidelines and the CDC’s 2008 disinfection and sterilization guideline — in practice, weekly biological (spore) testing of every sterilizer.
2. Request an Initial Inspection Within 30 Days of New Ownership
A dentist who becomes the owner of a new office or facility must request a Board inspection within 30 days of taking ownership, per NAC 631.1785.
3. Be Ready for Unannounced Random Inspections
Because the Executive Director can assign agents to inspect any office without notice under NAC 631.179, sterilization and spore testing logs should be organized and accessible at all times.
4. Document Every Test
Keep dated records of every spore test and its result, ready for review during any Board inspection.
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.
6. Maintain Bloodborne Pathogens Compliance with NVOSHA
Keep exposure control plans and Bloodborne Pathogens training current for Nevada’s own state OSHA program.
What to Do If a Spore Test Fails in Nevada
- 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 — this record is exactly what a Board inspection under NAC 631.1785 or NAC 631.179 will review

Who Enforces Spore Testing Requirements in Nevada?
1. Nevada State Board of Dental Examiners
Administers NAC 631.178 and conducts mandatory initial inspections of new dental offices (NAC 631.1785) as well as unannounced random inspections of any office (NAC 631.179), with the authority to issue cease-and-desist orders for noncompliant personnel.
2. Nevada OSHA (NVOSHA)
Enforces the Bloodborne Pathogens Standard and related workplace safety requirements through Nevada’s own OSHA-approved state plan, independent of Board licensure action.

How Often Should Nevada Dental Offices Test?
Nevada’s regulation doesn’t state a numeric interval in its own text — it requires compliance with both the CDC’s 2003 infection control guidelines and 2008 disinfection and sterilization guideline, which together point to weekly biological spore testing of every sterilizer. Because the standard is incorporated by reference to two CDC documents, it automatically tracks CDC guidance if either is updated.

Frequently Asked Questions: Nevada Dental Spore Testing
Does Nevada law require weekly biological spore testing?
Not by a fixed number in the regulation’s text. NAC 631.178 requires compliance with the CDC’s 2003 and 2008 infection control and sterilization guidelines, and the CDC’s own guidance calls for weekly spore testing — making it the practical, enforceable standard.
Does every new Nevada dental office get inspected?
Yes. NAC 631.1785 requires a dentist who becomes the owner of a new office or facility to request a Board inspection within 30 days of taking ownership, and the Board must complete that inspection within 90 days of the request.
Can the Nevada Board of Dental Examiners inspect an office without notice?
Yes. NAC 631.179 authorizes the Executive Director to assign agents to conduct random inspections of any dental office at any time, without advance notice to the dentist.
Does Nevada have its own OSHA program?
Yes. Nevada operates its own OSHA-approved state plan, Nevada OSHA (NVOSHA), which enforces standards equivalent to or more stringent than federal OSHA, including the Bloodborne Pathogens Standard.
What happens if a Nevada dental office fails an inspection?
The Executive Director issues a written notice identifying critical deficiencies, and the office is subject to reinspection. If personnel are found not in compliance after reinspection, the Executive Director may order them to immediately cease and desist from performing dental treatments until compliance is demonstrated.
