Are South Dakota Dental Offices Required to Perform Spore Testing?

Yes. South Dakota dental spore testing requirements sit inside a rule titled “Inspections for safety and sanitation” — and that placement is the whole story. ARSD 20:43:04:03 requires that “[t]he dentist must maintain the office in compliance with the Guidelines for Infection Control in Dental Health Care Settings, 2003, of the Center for Disease Control and Prevention,” and, in the very next sentence, that “[t]he dentist must permit inspection of the dental office at any time by anyone authorized by the board.”

The CDC obligation and the inspection consent are one rule. South Dakota did not write an infection control standard in one place and an inspection power in another; it wrote the duty and the means of checking it into a single paragraph, and attached license suspension or revocation to the front of it.

Spore testing is one of three types of sterilization monitoring the CDC recommends — mechanical, chemical, and biological. The 2003 guidelines the rule names call for monitoring sterilizers at least weekly by using a biological indicator with a matching control from the same lot number.

This guide covers what 20:43:04:03 requires, how the statutory ground behind it works, the clear-and-convincing evidentiary standard South Dakota applies, what the “statewide standard of competence” means, and what to do when a spore test fails.

The South Dakota Regulatory Framework for Dental Spore Testing

20:43:04:03 — Four Obligations in One Paragraph

The rule is short enough to take apart clause by clause, and each clause does separate work.

First, it states the consequence up front: “The board may suspend or revoke any license issued, after opportunity for hearing as provided in SDCL 1-26, for failure of a dentist to maintain the dentist’s entire dental office in a clean and sanitary condition without any accumulation of trash, debris, or filth.” Note “entire dental office” — the rule does not confine itself to operatories.

Second, it imports local law: “The dental office must be maintained in full compliance with all health requirements of the city or county, or both, in which it is located.” A municipal health code violation becomes a licensing matter.

Third, it names the CDC document: “The dentist must maintain the office in compliance with the Guidelines for Infection Control in Dental Health Care Settings, 2003, of the Center for Disease Control and Prevention.” The rule closes with a formal Reference note directing licensees to obtain the guidelines free of charge from the CDC — so there is no ambiguity about which document is meant.

Fourth, it secures access: “The dentist must permit inspection of the dental office at any time by anyone authorized by the board.” There is no complaint trigger, no notice period, and no reasonable-cause threshold in the rule text. Among the states in this guide, South Dakota’s inspection language is one of the broadest — comparable to Nevada’s authority for unannounced random inspections, and at the opposite end from states that require a documented determination of cause before entry.

Why the CDC Citation Settles the Interval

South Dakota’s rule prints no number. It does not have to. By requiring compliance with the 2003 CDC guidelines, the rule adopts what those guidelines say about sterilization monitoring, which includes:

Monitor sterilizers at least weekly by using a biological indicator with a matching control from the same lot number
Monitor each load with mechanical indicators — time, temperature, pressure — and chemical indicators
Place a chemical indicator inside each package, and on the outside where the internal one is not visible
Use a biological indicator for every load containing an implantable device
Maintain sterilization records in compliance with state and local regulations

The last item loops back to the rule’s local-health clause. A South Dakota practice’s recordkeeping obligations are the CDC’s, read together with whatever the city or county requires.

SDCL § 36-6A-59.1(12) — The Statutory Ground

The rule does not stand alone. SDCL § 36-6A-59.1 defines “unprofessional or dishonorable conduct” across twenty-six items, and item (12) is written to receive exactly this rule: “Failure to maintain adequate safety and sanitary conditions for a dental clinic in accordance with the standards set forth in this chapter or any rule promulgated thereunder.”

The chain is clean. The statute names the offense and points at the rules; the rule supplies the CDC standard and the inspection consent. A dentist who cannot produce weekly spore testing records has a rule problem under 20:43:04:03 and, through it, a statutory problem under § 36-6A-59.1(12) — plus, independently, item (7), violating any provision of the chapter or any rule.

Two further items reach the same conduct from different angles. Item (6) covers “[a]llowing professional incompetence by a dental hygienist or dental auxiliary working under his or her supervision due to a deliberate or negligent act or acts or failure to act” — relevant wherever an assistant runs the sterilizer. Item (23) covers “[a]ny practice or conduct which tends to constitute a danger to the health, welfare, or safety of the public or patients.”

§ 36-6A-59 — Clear and Convincing, and a Statewide Standard

SDCL § 36-6A-59 sets the frame for every disciplinary case. Each licensee “shall conduct his or her practice in accordance with the standards established by the board,” and is subject to sanctions “upon satisfactory proof by clear and convincing evidence” of professional incompetence, unprofessional or dishonorable conduct, or a violation of the chapter.

Clear and convincing is a higher bar than the preponderance standard used in several other states in this guide. It cuts both ways for a practice: harder for the Board to meet, and correspondingly easier to meet where the evidence is a documentary absence — a log that does not exist is not a matter of competing testimony.

The section then defines professional incompetence as “a deviation from the statewide standard of competence, which is that minimum degree of skill and knowledge necessary for the performance of characteristic tasks of a licensee… in at least a reasonably safe and effective way,” with a national standard applied where the services “are not commonly provided by a licensee or registrant in this state.” Sterilization monitoring is a characteristic task of every dental practice, so the statewide standard governs — and the statewide standard is set by the rule that names the CDC guidelines.

No State OSHA Plan

South Dakota does not operate an OSHA-approved State Plan. Federal OSHA enforces workplace safety in South Dakota dental practices directly, including the Bloodborne Pathogens Standard, 29 C.F.R. § 1910.1030. Board discipline and OSHA enforcement proceed independently on the same facts.

What South Dakota Dental Offices Must Do

1. Test Every Sterilizer Weekly
Biological monitoring at least weekly with a matching control from the same lot, per the CDC 2003 guidelines named in ARSD 20:43:04:03.

2. Be Ready for an Unannounced Visit
The rule requires permitting inspection at any time by anyone authorized by the board. Compliance is a standing condition, not a state you reach before a scheduled visit.

3. Document Every Test and Every Load
Dated spore test results and cycle records, kept per CDC recordkeeping recommendations and any city or county requirement.

4. Keep the Entire Office Clean and Sanitary
The rule names the “entire dental office” and calls out accumulation of trash, debris, or filth — including areas outside the operatory.

5. Maintain Full Bloodborne Pathogens Compliance
29 C.F.R. § 1910.1030 is enforced in South Dakota by federal OSHA, separately from Board action.

6. Supervise Auxiliaries Who Process Instruments
SDCL § 36-6A-59.1(6) makes allowing professional incompetence by a supervised hygienist or auxiliary its own ground.

What to Do If a Spore Test Fails in South Dakota

Remove the sterilizer from service immediately
Review loading technique, indicator expiration, and cycle settings for operator error
Retest with biological, mechanical, and chemical indicators after correcting any procedural problem
If the repeat test is positive, keep the unit out of service until it has been inspected or repaired and the cause determined
Recall and reprocess, to the extent possible, all items processed since the last negative spore test
Rechallenge with three consecutive empty-chamber biological indicator cycles before returning the unit to use
Document the failure, the corrective action, and the retest result — following the CDC protocol is what 20:43:04:03 requires

Who Enforces Spore Testing Requirements in South Dakota?

1. South Dakota State Board of Dentistry
Administers ARSD 20:43:04:03, inspects dental offices, and may suspend or revoke a license after hearing under SDCL ch. 1-26, applying SDCL §§ 36-6A-59 and 36-6A-59.1.

2. City and County Health Authorities
Their health requirements are imported into the Board’s rule, so local compliance is part of the licensing standard.

3. Federal OSHA
Enforces 29 C.F.R. § 1910.1030 and related employee-protection requirements directly, since South Dakota has no OSHA-approved State Plan.

Frequently Asked Questions: South Dakota Dental Spore Testing

Does South Dakota law require weekly biological spore testing?

Yes, by incorporation. ARSD 20:43:04:03 requires compliance with the CDC’s 2003 infection control guidelines, which call for weekly biological monitoring of every sterilizer.

Can the Board inspect a South Dakota dental office without notice?

The rule states that the dentist “must permit inspection of the dental office at any time by anyone authorized by the board.” There is no complaint trigger or notice requirement written into the rule text.

What happens if the office fails an inspection?

Under ARSD 20:43:04:03 the Board may suspend or revoke the license after an opportunity for hearing under SDCL ch. 1-26. The corresponding statutory ground is SDCL § 36-6A-59.1(12), failure to maintain adequate safety and sanitary conditions for a dental clinic.

What standard of proof applies?

Clear and convincing evidence, under SDCL § 36-6A-59 — a higher bar than the preponderance standard some states apply.

Do local health rules matter?

Yes. The rule requires the office to be maintained “in full compliance with all health requirements of the city or county, or both, in which it is located,” so municipal or county requirements are folded into the licensing standard.

When was the rule last updated?

ARSD 20:43:04:03 was most recently amended effective April 25, 2012, with earlier amendments in 1999, 1992, 1986, 1984, and 1980.

Does South Dakota have its own OSHA program?

No. South Dakota is not an OSHA-approved State Plan state, so federal OSHA enforces the Bloodborne Pathogens Standard and related requirements in South Dakota dental practices directly.
