MO Dental Hygiene Jurisprudence cheat sheet

The Dental Practice Act is codified in Chapter 332 of the Missouri Revised Statutes (RSMo); the Missouri Dental Board enforces it through rules in Title 20, Division 2200 of the Code of State Regulations (CSR).

Dental hygiene is a licensed profession separate from dentistry: a hygienist may perform services only under the level of supervision the Act authorizes, and may not diagnose, prescribe, or perform procedures reserved to dentists.

Scope of hygiene practice centers on preventive services - oral prophylaxis, scaling and root planing, polishing, fluoride application, sealants, and patient education - plus radiographs and other duties the Board assigns by rule.

A dental hygienist must practice under the supervision of a licensed dentist; the Act's supervision definitions (direct, indirect, general) determine which services require the dentist's presence.

The Act defines key terms precisely - "dental hygienist," "supervision," "direct supervision," "collaborative practice," and "dental office" - and those definitions control how Board rules are applied.

Only a person licensed by the Missouri Dental Board may hold out as a dental hygienist or use titles such as RDH; unlicensed practice is a statutory violation subject to injunctive and disciplinary action.

Local anesthesia and nitrous oxide administration by hygienists are permitted only after additional Board-approved training and certification, and only under the supervision level the Act or rules specify.

The Act authorizes the Board to adopt rules implementing licensure, supervision, infection control, and discipline; a rule cannot expand hygienist scope beyond what the statute permits.

Licensure requires graduation from an accredited dental hygiene program, successful completion of a Board-approved clinical and written examination, and a completed application with the required fee.

Missouri issues a dental hygienist license; the license must be renewed on the Board's cycle, and practicing on an expired license is unlicensed practice.

Renewal requires the continuing education hours the Board sets by rule, completion of the required jurisprudence component, and attestation of lawful practice status.

Continuing education must be earned in Board-approved subject areas and documented; records are subject to audit and falsified CE is a disciplinary ground.

A lapsed license may be reinstated only through the Board's reinstatement process, which can require additional CE, fees, or reexamination.

Licensees must notify the Board of changes of name or address within the time the rules require, and must respond truthfully to Board inquiries.

Licensure by credentials or reciprocity depends on holding a current license in another jurisdiction with substantially equivalent requirements and on verification of that license.

Fees are set by the Board; failure to pay renewal fees or submit required documentation results in a delinquent or inactive license, not automatic revocation.

Direct supervision: the dentist must be physically present in the office, examine the patient, and be available during the procedure.

Indirect supervision: the dentist has authorized the procedure, examined the patient, and is available by phone or in person but need not be in the room.

General supervision: the dentist has authorized the services and the patient of record, but need not be on the premises at the time of treatment.

Prophylaxis, polishing, and routine scaling are typically performed under general supervision for a patient of record; radiographs and local anesthesia follow the specific rule for that service.

Collaborative practice arrangements allow a hygienist to treat patients without the dentist on site only where the Act and Board rules authorize it and the required agreement or protocol is in place.

Delegation is personal to the supervising dentist: the dentist must not delegate a procedure outside the hygienist's scope, and the hygienist must refuse any task beyond that scope.

A hygienist may not diagnose, treatment-plan, prescribe, or perform irreversible or surgical procedures; those remain the dentist's responsibility.

Supervision status must be documented in the patient record, including the authorizing dentist and the services provided under each level.

Board rules appear in 20 CSR 2200 and cover licensure, supervision, infection control, records, CE, and disciplinary procedure; they carry the force of law.

Rules specify the minimum equipment, sterilization monitoring, and waterline maintenance standards a dental office must meet.

The Board may inspect or investigate a practice on complaint; licensees must cooperate with investigations and produce records on lawful request.

Rule violations can be charged as violations of the Act even where no patient harm occurred, because the Board regulates minimum standards of practice.

Rules define what counts as approved continuing education, including limits on hours from certain formats and required subject matter.

Board rules govern advertising and representation of credentials; a hygienist may not misrepresent licensure status or specialty qualifications.

The Board publishes rule changes through the Missouri Register; licensees are charged with knowledge of current rules regardless of personal notice.

Failure to comply with a Board order, subpoena, or probation condition is itself a separate ground for discipline.

Standard precautions apply to every patient: treat all blood and body fluids as potentially infectious regardless of known diagnosis.

Hand hygiene is performed before and after patient contact and after glove removal; gloves are changed between patients and when torn.

Critical items (instruments that penetrate tissue) must be cleaned and sterilized by heat; sterilization is monitored with biological indicators at the interval the rules require.

Semicritical items contact mucosa and require at least high-level disinfection or sterilization according to the manufacturer's instructions.

Dental unit waterlines must be maintained with the treatment the rules and manufacturer specify, and monitored for microbial quality.

Sharps are discarded immediately in puncture-resistant containers; needlestick injuries require immediate first aid, reporting, and post-exposure evaluation.

Surface barriers or disinfection are used for clinical contact surfaces between patients; housekeeping surfaces require routine cleaning.

Vaccination, PPE, and posted exposure-control plans are required elements of the office's infection-control program.

The patient record must be accurate, contemporaneous, and complete: chart entries document date, services, supervision status, and any adverse events.

Records are the property of the practice, but patients have a right of access to their records under Missouri law and HIPAA, subject to permitted exceptions.

Confidentiality protects all patient-identifying information; disclosure requires patient authorization or a legal exception such as mandatory reporting or court order.

Minimum necessary disclosure applies when sharing information for treatment, payment, or operations; casual discussion of patients is an ethics violation.

Informed consent requires disclosure of the procedure, its risks and alternatives, and the patient's voluntary agreement, documented in the record.

Altering or backdating a record after an incident is fraud and a separate disciplinary ground; corrections must be dated and clearly identified.

Ethical duties include competence within scope, honesty in billing and coding, and avoiding conflicts of interest such as self-referral.

Mandatory reporting of suspected child or elder abuse overrides confidentiality; the report is made to the designated authority, not to the family.

Grounds for discipline include unlicensed or out-of-scope practice, gross negligence, incompetence, fraud, substance impairment, and conviction of certain crimes.

The Board may issue a reprimand, place a license on probation with conditions, suspend, or revoke; it may also assess costs and require remediation.

Discipline begins with a complaint and investigation; the licensee receives notice of the charges and an opportunity to respond.

A contested case is heard under the Missouri Administrative Procedure Act, with the right to counsel, to present evidence, and to cross-examine.

The Board's final decision may be appealed to the circuit court under the standard of review for administrative decisions.

Summary suspension is available where continued practice presents an immediate danger to the public, followed by a hearing.

Practicing during a suspension or after revocation is unlicensed practice and supports additional discipline and criminal exposure.

Failure to report a conviction, a malpractice payment, or a disciplinary action in another state within the required time is itself a ground for discipline.
