DENTAL HYGIENE
JURISPRUDENCE &
ETHICS
PART 0: THE NAVIGATOR
● Tier 1 (Questions 1–28) - Foundational Syntax & Application: Licensing parameters, basic
supervision designations (General, Indirect, Direct), Continuing Education (CE)
mathematics, and fundamental scope of practice boundaries.
● Tier 2 (Questions 29–58) - Complex Application & Simulation: Patient record laws,
Expanded Practice Dental Hygienist (EPDH) parameters, anesthesia/sedation
administration, the 2026 Botulinum Toxin regulations, and mandatory reporting protocols.
● Tier 3 (Questions 59–88) - Grandmaster Synthesis: High-stakes disciplinary matrices,
Collaborative Agreement pharmacology, impairment and fraud interventions, and complex
multi-variable ethical dilemmas.
PART I: THE PRIMER
Mastering the Oregon Dental Practice Act and Administrative Rules (OAR 818) translates
directly into elite clinical autonomy and bulletproof professional liability management. This test
bank forges practitioners who can navigate complex jurisprudence to safely expand patient
access while avoiding catastrophic Board discipline.
● The Supervision Absolutes: Local anesthesia requires general supervision; Nitrous
oxide requires indirect supervision (dentist on premises). Expanded Practice Dental
Hygienists (EPDH) cannot administer nitrous oxide without a dentist present.
● The "No Cut, No Diagnose" Law: Hygienists cannot diagnose (except for dental hygiene
needs), extract, or cut hard/soft tissue. Exceptions exist strictly for root planing and EPDH
Interim Therapeutic Restorations (ITR).
● The Record Retention Standard: Patient records must be kept for exactly 7 years from
the last entry. Records cannot be held hostage for unpaid clinical bills.
● The 24/7 Mandate: Dental hygienists are mandated reporters for child and elder abuse
24 hours a day, 7 days a week, regardless of whether they are on duty.
● The 2026 Aesthetic Update: RDHs with a local anesthesia endorsement may administer
Botulinum Toxin Type A (Botox) under general supervision, strictly following a 10-hour
clinical course and obtaining written informed consent.
PART II: THE ELITE TEST BANK
Q1: An Oregon dental hygienist is preparing for their biennial license renewal. They hold a
,standard RDH license. Based on the principles of OAR 818-021-0070, which CE portfolio is the
MOST ACCURATE for compliance? A) 36 total hours, including 3 hours of medical
emergencies and 2 hours of infection control. B) 24 total hours, including 3 hours of medical
emergencies, 2 hours of infection control, and 2 hours of cultural competency. C) 40 total hours,
matching the dentist requirement, all via home study. D) 24 total hours, provided at least 12
hours are completed via live, in-person attendance.
● The Answer: B (24 total hours, including 3 hours of medical emergencies, 2 hours of
infection control, and 2 hours of cultural competency.)
● Distractor Analysis:
○ A is incorrect: 36 hours is the specific requirement for an Expanded Practice Dental
Hygienist (EPDH), not a standard RDH.
○ C is incorrect: 40 hours is the standard solely for licensed dentists.
○ D is incorrect: Oregon administrative rules permit all 24 continuing education hours
to be completed via home study.
The Mentor's Analysis: Regulatory bodies engineer CE requirements to guarantee baseline
emergency and cultural readiness. When tracking your biennial education, the immediate
priority is satisfying the core clinical mandates. By utilizing the specific 24-hour metric with
cultural competency, you bypass the common trap of failing a state audit.
Professional/Academic Intuition: Standard hygiene requires 24 hours; EPDH requires 36;
both require specific emergency and cultural credits.
Q2: A supervising dentist asks a new RDH to perform a prophylaxis on a patient who has not
yet received a comprehensive exam. Based on the principles of Authorization to Practice (OAR
818-035), which action is MOST APPROPRIATE? A) The RDH must refuse until the dentist
performs a clinical exam. B) The RDH may perform the prophylaxis under direct supervision
only. C) The RDH may perform the prophylaxis under general supervision, provided the patient
is scheduled for an exam within 15 business days. D) The RDH may perform the prophylaxis but
cannot legally take radiographs.
● The Answer: C (The RDH may perform the prophylaxis under general supervision,
provided the patient is scheduled for an exam within 15 business days.)
● Distractor Analysis:
○ A is incorrect: Oregon explicitly authorizes hygienists to gather data and perform
hygiene services prior to a new patient exam.
○ B is incorrect: Direct supervision is not required for fundamental hygiene services.
○ D is incorrect: Exposing radiographs is a permitted preliminary data-gathering
function.
The Mentor's Analysis: The law respects the hygienist's role in initiating the diagnostic data
pipeline. When treating an unexamined patient, the immediate priority is ensuring continuity of
care. By utilizing the 15-business-day scheduling rule, you bypass the common trap of delaying
preventative interventions. Professional/Academic Intuition: You may initiate hygiene care
under general supervision, provided the diagnostic loop closes within 15 days.
Q3: A dentist instructs a dental hygienist to use a high-speed handpiece to prepare a Class I
cavity, stating the dentist will place the final composite. Based on the principles of Prohibited
Acts (OAR 818-035-0025), which conclusion is MOST ACCURATE? A) The hygienist may
prepare the tooth if they hold a Restorative Functions Endorsement (RFE). B) The hygienist
may prepare the tooth under the direct supervision of the dentist. C) The hygienist must refuse,
as operatively preparing teeth is strictly prohibited. D) The hygienist may prepare the tooth using
only a slow-speed handpiece.
● The Answer: C (The hygienist must refuse, as operatively preparing teeth is strictly
, prohibited.)
● Distractor Analysis:
○ A is incorrect: An RFE permits the placement, condensing, and carving of
restorations, never the cutting of hard tissue.
○ B is incorrect: Supervision level cannot override a statutory scope prohibition.
○ D is incorrect: The prohibition applies to the act of operatively preparing teeth,
regardless of handpiece RPM.
The Mentor's Analysis: Scope of practice boundaries are absolute legal firewalls. When asked
to surgically alter tooth morphology, the immediate priority is protecting the patient and your
license. By utilizing strict scope adherence, you bypass the common trap of committing
unlicensed surgery. Professional/Academic Intuition: Hygienists manage biofilm and finish
restorations; dentists cut the preparation.
Q4: A patient formally requests their digital patient records. The patient owes a $300 balance.
Based on the principles of Patient Records (OAR 818-012-0070), which action is IMMEDIATELY
required? A) Withhold the records until the $300 balance is paid in full. B) Provide the digital
records within 14 calendar days, charging no more than $5 if the files are under 25 MB. C)
Provide the records immediately and waive all duplication fees. D) Send the records only to
another licensed dental provider.
● The Answer: B (Provide the digital records within 14 calendar days, charging no more
than $5 if the files are under 25 MB.)
● Distractor Analysis:
○ A is incorrect: It is explicitly defined as unprofessional conduct to withhold records
due to unpaid bills.
○ C is incorrect: The law permits a 14-day window and allows standard duplication
fees.
○ D is incorrect: Patients have a sovereign right to directly access their own health
data.
The Mentor's Analysis: Health records are patient property held in trust by the clinician. When a
debtor requests their chart, the immediate priority is compliance within 14 days. By utilizing the
state-mandated fee schedule, you bypass the common trap of using clinical data for financial
extortion. Professional/Academic Intuition: Never hold clinical records hostage to collect a
financial debt.
Q5: During a prophylaxis, a hygienist notices physical bruising on an elderly patient consistent
with abuse. The hygienist is off-duty later that day. Based on Oregon Mandatory Reporting
guidelines, what is the MOST ACCURATE requirement? A) The hygienist must report the abuse
only if it occurred during normal clinic hours. B) The hygienist is a 24/7 mandatory reporter and
must report the abuse immediately. C) The hygienist must chart the findings and leave the
reporting to the supervising dentist. D) The hygienist must confront the caregiver before filing a
state report.
● The Answer: B (The hygienist is a 24/7 mandatory reporter and must report the abuse
immediately.)
● Distractor Analysis:
○ A is incorrect: Mandatory reporting in Oregon applies 24/7, whether on or off the
clock.
○ C is incorrect: The duty to report is an individual, non-delegable mandate.
○ D is incorrect: Confronting abusers jeopardizes the victim's safety and is not legally
advised.
The Mentor's Analysis: The state grants licensure with the implicit contract that you protect the
, vulnerable. When encountering suspected abuse, the immediate priority is alerting authorities.
By utilizing immediate, individual reporting, you bypass the common trap of the clinical
bystander effect. Professional/Academic Intuition: Mandatory reporting is individual,
immediate, and 24/7—your badge never comes off.
Q6: A hygienist with a Nitrous Oxide Permit is working while the dentist leaves the building for
lunch. A patient requests nitrous oxide. Based on Anesthesia rules (OAR 818-026), which action
is MOST ACCURATE? A) The hygienist may administer nitrous oxide because they hold the
specific permit. B) The hygienist must refuse, as nitrous oxide administration requires the
indirect supervision of a dentist. C) The hygienist may administer nitrous oxide if they hold an
Expanded Practice Permit (EPP). D) The hygienist may administer nitrous oxide under standing
written orders.
● The Answer: B (The hygienist must refuse, as nitrous oxide administration requires the
indirect supervision of a dentist.)
● Distractor Analysis:
○ A is incorrect: A permit qualifies the provider but does not override the statutory
supervision level.
○ C is incorrect: An EPP explicitly prohibits administering nitrous oxide without the
dentist on the premises.
○ D is incorrect: Standing orders equate to general supervision; nitrous oxide strictly
requires indirect supervision.
The Mentor's Analysis: Inhalation sedation alters the central nervous system and demands
immediate rescue capabilities. When the dentist leaves the premises, the immediate priority is
securing the sedation equipment. By utilizing the strict definition of indirect supervision, you
bypass the common trap of illegal autonomous sedation. Professional/Academic Intuition:
Indirect supervision mandates the dentist's physical presence in the building; if the
doctor leaves, the gas stays off.
Q7: A dentist places a hand securely over a screaming pediatric patient's mouth and pinches
their nose to restrict airflow, forcing compliance. Based on Unacceptable Patient Care (OAR
818-012-0010), this action is: A) Acceptable if the parents signed a prior consent form. B)
Defined as Hand Over Mouth Airway Restriction (HOMAR) and is strictly prohibited on any
patient. C) Standard Hand Over Mouth (HOM) and is legally acceptable during extreme
outbursts. D) Permitted only if the hygienist assists by holding the patient's hands.
● The Answer: B (Defined as Hand Over Mouth Airway Restriction (HOMAR) and is strictly
prohibited on any patient.)
● Distractor Analysis:
○ A is incorrect: While HOM requires consent, HOMAR (restricting the airway) is
unequivocally banned.
○ C is incorrect: Pinching the nose restricts the airway, escalating this to a prohibited
HOMAR violation.
○ D is incorrect: Assisting in a prohibited act constitutes unprofessional conduct.
The Mentor's Analysis: Modern behavioral management prioritizes physiological safety over
forced compliance. When a provider restricts an airway, the immediate priority is halting the
procedure. By recognizing HOMAR as a strict liability violation, you bypass the common trap of
confusing it with standard, consented HOM. Professional/Academic Intuition: You may cover
the mouth with consent; you may never restrict the airway.
Q8: A dentist instructs the hygienist to administer the annual influenza vaccine to a patient.
Based on Vaccine Administration rules (OAR 818-012-0006), which action is MOST
ACCURATE? A) The hygienist may administer the vaccine under direct supervision. B) The
