Maryland Dental Spore Testing Requirements (2026 Guide)
Are Maryland Dental Offices Required to Perform Spore Testing?
Yes. Maryland dental offices are required to perform biological spore testing under COMAR 10.44.36.05 — the Maryland State Board of Dental Examiners’ new Private Dental Offices—Infection Control regulation, effective January 19, 2026. The rule explicitly lists “Biological spore testing” as a required component of sterilization monitoring, alongside chemical and mechanical monitoring, to be performed “in accordance with the manufacturer’s instructions for use.”
Maryland’s framework is built around a “supervising dentist” — a licensed dentist (including a solo practitioner) that every private dental office must designate as responsible for infection control activities, including spore testing. This requirement traces back to 2024 legislation (Senate Bill 335) and is now fully implemented through COMAR 10.44.36, which incorporates the CDC’s 2003 Guidelines for Infection Control in Dental Health-Care Settings by reference.
Maryland also stands out for a second, separate regulation: COMAR 10.44.34, effective August 18, 2025, which authorizes the Board to conduct unannounced inspections of dental offices — including inspections triggered by a referral from Maryland’s Commissioner of Labor and Industry, the head of the state’s MOSH program. That cross-agency referral pathway is unique among the states in this guide and ties spore testing compliance directly to workplace safety enforcement.
This guide covers what COMAR 10.44.36 and 10.44.34 actually require, the supervising dentist structure, the unannounced inspection and correction process, and how Maryland’s Occupational Safety and Health (MOSH) program adds a second layer of enforcement.

The Maryland Regulatory Framework for Dental Spore Testing
COMAR 10.44.36 — Private Dental Offices—Infection Control
Maryland’s core sterilization monitoring requirement is one of the newest in the country. COMAR 10.44.36 took effect January 19, 2026, and defines a “supervising dentist” as:
“A dentist licensed in the State, including a solo practitioner, who is responsible for all infection control activities within a private dental office as set forth in this chapter.” (COMAR 10.44.36.01.B(5))
Under 10.44.36.05.A(2)(f), the supervising dentist must provide and maintain:
“Sterilization monitoring of reusable dental equipment and instruments in accordance with the manufacturer’s instructions for use, including: (i) Biological spore testing; (ii) Chemical monitoring; and (iii) Mechanical monitoring.”
Rather than stating a fixed testing interval in the regulatory text, Maryland ties the standard to the sterilizer manufacturer’s IFU — and separately incorporates the CDC’s 2003 infection control guidelines by reference under 10.44.36.02. Those CDC guidelines establish weekly biological monitoring as the baseline expectation, so Maryland practices should treat “at least weekly” as the practical floor even though the COMAR text itself doesn’t use that word.
The “Supervising Dentist” Model — Maryland’s Compliance Structure
Maryland’s approach is distinct from most states in this guide because responsibility for spore testing and other structural infection control activities is assigned to a single named individual per office, not just “the dentist” generally. Under Health Occupations Article §4-104 (added by 2024’s Senate Bill 335):
- Every owner of a private dental office must designate a licensed dentist as the supervising dentist.
- The supervising dentist must complete registration with the Board and display that registration (COMAR 10.44.36.03–.04).
- The supervising dentist is responsible for CDC guideline adherence, spore testing, water quality testing, PPE availability, sharps containers, biohazard waste removal, and staff training.
- A supervising dentist may oversee up to three private dental offices, provided they’re close enough for personal oversight.
- If a supervising dentist steps down, the owner must immediately designate an interim supervising dentist.
Individual dentists who are not the supervising dentist remain personally responsible for their own PPE use and instrument sterilization (COMAR 10.44.36.06), but structural compliance — including the spore testing program — sits with the supervising dentist.
COMAR 10.44.34 — Unannounced Inspections for CDC Compliance
Maryland backs its infection control rule with a dedicated inspection chapter, effective August 18, 2025. Under COMAR 10.44.34.02, the Board may conduct an unannounced inspection of a dental office upon receipt of a written, signed complaint alleging noncompliance with CDC universal precautions guidelines — including a referral from the Commissioner of Labor and Industry, who oversees MOSH. That cross-referral mechanism means a MOSH workplace safety complaint can trigger a Board of Dentistry infection control inspection, and vice versa.
If violations are found, COMAR 10.44.34.03 gives the licensee 30 days from written notice to correct them (the Board can shorten this window if public health requires it, or grant an extension on request), followed by a re-inspection. COMAR 10.44.34.04 makes clear that failing to allow an inspection, or failing to correct violations within the deadline, can each independently trigger disciplinary action — and the Board can pursue concurrent or summary action against a licensee found to have violated CDC guidelines.
MOSH — Maryland’s State OSHA Plan
Maryland operates its own OSHA-approved state plan through the Maryland Occupational Safety and Health (MOSH) program, part of the Division of Labor and Industry. MOSH covers all private-sector workplaces, including dental practices, and enforces the federal Bloodborne Pathogens Standard alongside Maryland-specific requirements. This gives Maryland dental offices two distinct enforcement paths for infection control: the State Board of Dental Examiners for licensure compliance under COMAR 10.44.36, and MOSH for workplace safety compliance — with the Commissioner of Labor and Industry able to refer complaints directly into the Board’s inspection process.
What Maryland’s Spore Testing Rule Actually Requires
1. Biological Monitoring (Spore Testing)
Every reusable sterilizer must be monitored using a biological indicator per the manufacturer’s IFU, consistent with the CDC’s 2003 guidelines incorporated into COMAR 10.44.36.02. A matching control indicator from the same lot should accompany each test.
2. Chemical Monitoring
Chemical indicators are required alongside biological monitoring under 10.44.36.05.A(2)(f)(ii), consistent with CDC guidance to place an indicator inside every instrument package.
3. Mechanical Monitoring
Time, temperature, and pressure (or equivalent cycle parameters) must be verified for each load under 10.44.36.05.A(2)(f)(iii).
4. Water Quality Testing
Maryland’s supervising dentist duties extend beyond sterilization: periodic water quality testing to EPA drinking-water standards is a separate, explicit requirement under 10.44.36.05.A(2)(e).
Annual Training Requirements
COMAR 10.44.36.05.B–C requires the supervising dentist to train clinical staff upon hire, before they perform clinical duties, and at minimum annually thereafter. The required training topics include:
- Standard and transmission-based precautions
- Hand hygiene
- Personal protective equipment
- Respiratory hygiene / cough etiquette
- Sharps safety
- Safe injection practices
- Sterilizing and disinfecting clinical contact and housekeeping surfaces
- Spore testing
- Water quality testing
- The OSHA Bloodborne Pathogens Standard (29 CFR §1910.1030)
Written Policies, Procedures, and Records
Under COMAR 10.44.36.05.D–F, the supervising dentist must maintain evidence-based written policies and procedures — grounded in current CDC guidelines and regulatory requirements — that are readily available to clinical staff and updated at least annually, or more often as guidance changes. Adequate written records of spore testing and the other infection control activities must be maintained in each office. The regulation does not specify a fixed retention period in years, so practices should default to standard industry recordkeeping practice and keep documentation available for Board review.
What to Do If a Spore Test Fails in Maryland
COMAR 10.44.36 does not spell out a state-specific positive-test protocol the way some states do, which means Maryland practices should follow CDC guidance directly:
- Remove the sterilizer from service immediately
- Review loading procedures, indicator expiration, and cycle parameters for cause
- Retest after any corrective action or repair before returning the unit to service
- Document the failure, corrective steps, and retest result as part of the written records required under 10.44.36.05.F

Who Enforces Spore Testing Requirements in Maryland?
1. Maryland State Board of Dental Examiners
The Board administers COMAR 10.44.36 and 10.44.34, registers supervising dentists, and can conduct unannounced inspections on complaint. Violations of the infection control chapter constitute unprofessional conduct under Health Occupations Article §4-315, subject to disciplinary hearing requirements in §4-318.
2. Maryland Occupational Safety and Health (MOSH)
MOSH enforces the Bloodborne Pathogens Standard in Maryland dental workplaces and, through the Commissioner of Labor and Industry, can refer infection control complaints directly to the Board of Dental Examiners for inspection under COMAR 10.44.34.02.

How Often Should Maryland Dental Offices Test?
Maryland ties its spore testing standard to the sterilizer manufacturer’s instructions for use, layered with the CDC’s 2003 guidelines incorporated by reference — which set weekly biological monitoring as the baseline. Treat weekly testing as a floor, not a target, especially given Maryland’s unannounced inspection authority.

Frequently Asked Questions: Maryland Dental Spore Testing
Is biological spore testing legally required in Maryland?
Yes. COMAR 10.44.36.05.A(2)(f)(i) explicitly requires biological spore testing of reusable dental equipment and instruments, alongside chemical and mechanical monitoring, in accordance with the manufacturer’s instructions for use.
Who is responsible for spore testing compliance in a Maryland dental office?
The office’s designated “supervising dentist” — a role every private dental office, including solo practices, must assign to a licensed dentist registered with the Board. The supervising dentist is responsible for spore testing, water quality testing, staff training, and written infection control policies.
Does Maryland require weekly spore testing specifically?
The COMAR text ties testing to the sterilizer manufacturer’s IFU rather than stating “weekly” directly, but it incorporates the CDC’s 2003 infection control guidelines by reference, and those guidelines establish weekly biological monitoring as the minimum standard.
Can the Board inspect a Maryland dental office without notice?
Yes. Under COMAR 10.44.34.02, the Board may conduct an unannounced inspection upon receipt of a written, signed complaint alleging noncompliance with CDC universal precautions — including a referral from the Commissioner of Labor and Industry, who also oversees MOSH.
How long do we have to fix a violation found during a Board inspection?
Generally 30 days from written notice, per COMAR 10.44.34.03. The Board can shorten that window if it considers correction urgent for public health, or grant an extension on request. A re-inspection follows once corrections are reported.
Does MOSH inspect Maryland dental offices too?
Yes. MOSH, Maryland’s state OSHA plan, enforces the Bloodborne Pathogens Standard in private dental workplaces independently of the Board of Dental Examiners — and can refer infection control concerns to the Board through the Commissioner of Labor and Industry.
Can a solo practitioner be their own supervising dentist?
Yes. COMAR 10.44.36.01.B(5) explicitly defines “supervising dentist” to include a solo practitioner.
