Lecture Notes: Ethics & Mandatory Notifications in Australian Dental Practice
1. Introduction
Ethical dental practice is a cornerstone of safe, competent, and lawful health care in Australia. For dentists, dental specialists, and dental practitioners, the ethical and legal obligations extend far beyond technical proficiency. The modern regulatory framework—particularly the Dental Board of Australia (DBA), the Australian Health Practitioner Regulation Agency (AHPRA), and mandatory reporting laws such as those concerning child protection—requires practitioners to uphold strict standards of conduct, transparency, and patient protection.
This lecture note covers the essential ethical and legal concepts related to:
-
Ethical foundations in dental practice
-
Requirements for valid consent: voluntary, informed, and documented
-
Exceptions to confidentiality and disclosure
-
Mandatory notifications under the Health Practitioner Regulation National Law (National Law)
-
Types of notifiable conduct: professional misconduct, impairment, intoxication, and practice placing public at risk
-
Mandatory reporting obligations for child safety across Australian jurisdictions
-
Application to real-world clinical dentistry scenarios
2. Ethical Principles in Australian Dentistry
Ethics in dentistry is grounded in a set of universal principles that guide every aspect of clinical judgment, professional behavior, and patient interaction. These principles form the ethical basis from which consent, confidentiality, mandatory notifications, and professional conduct standards are derived.
2.1 Key Ethical Principles
2.1.1 Autonomy
The principle of autonomy obliges the dentist to respect a patient’s right to make their own choices about treatment. This includes:
-
The right to accept or refuse treatment
-
The right to receive truthful and complete information
-
The right to be free from coercion or manipulation
This principle is directly tied to the ethical and legal requirements of voluntary, informed, and documented consent.
2.1.2 Beneficence
Practitioners must act in the best interests of the patient. This means prioritizing their health, safety, and wellbeing, and recommending treatments that genuinely benefit them.
2.1.3 Non-maleficence
The classic medical rule: "Do no harm."
Practitioners must avoid treatments or behaviors that can cause injury, suffering, or risk. This includes avoiding treatment while impaired or intoxicated.
2.1.4 Justice
Justice refers to fairness, equal treatment, and appropriate use of resources. Dentists must not discriminate, must manage waiting lists ethically, and must price treatments fairly.
2.1.5 Veracity
Truthfulness in communication is essential. Misleading claims, withholding information, falsifying records, or providing incomplete explanations violate ethical and legal standards.
2.1.6 Confidentiality
Patient information is private and must be protected unless an exception applies. Confidentiality supports trust in the dentist–patient relationship.
3. Consent in Dental Practice
Consent is a legal and ethical requirement. A practitioner who treats a patient without valid consent risks legal liability, civil litigation for battery or negligence, professional disciplinary action, and ethical violations.
3.1 The Three Core Elements of Valid Consent
3.1.1 Consent Must Be Voluntary
Voluntary consent means:
-
The patient decides freely
-
No coercion, pressure, manipulation, or deception
-
No misuse of authority or urgency
Practitioners cannot subtly force a patient into accepting a treatment plan, either by overwhelming them with jargon, overstating risks of refusal, or implying that decline of treatment will damage the professional relationship.
Populations needing special consideration for voluntariness:
-
Children and minors
-
People with cognitive impairments
-
Elderly patients dependent on carers
-
Individuals with limited English proficiency
-
Patients in pain or distress
3.1.2 Consent Must Be Informed
Informed consent requires the practitioner to give the patient material information so they can make a meaningful decision. Material information includes:
-
The nature and purpose of the proposed procedure
-
The benefits of treatment
-
The risks—especially those that are material or significant
-
Alternatives, including no treatment
-
Costs
-
Prognosis with and without treatment
-
Who will perform the procedure and what their qualifications are
Informed consent is a process, not a signature. The practitioner must ensure the patient understands what is explained. Tools such as diagrams, models, translated materials, and interpreters may be necessary.
3.1.3 Consent Must Be Documented
Documentation provides legal protection and demonstrates adherence to professional standards.
Accepted forms of documentation include:
-
Progress notes summarizing the consent discussion
-
Signed informed consent forms (especially for invasive procedures)
-
Written treatment plans
-
Digital records or scanned forms
-
Audio or video recordings where appropriate
Documentation should include:
-
Date and time of discussion
-
Information provided
-
Patient questions and responses
-
Confirmation of understanding
-
Patient’s voluntary agreement
4. Exceptions to Confidentiality and Consent
Australian law recognizes that confidentiality is not absolute. There are situations where dentists must or may disclose information without consent.
4.1 Disclosure Where There Is Risk of Serious Harm
A practitioner may disclose confidential information if:
-
The patient is at risk of causing serious harm to themselves
-
The patient intends to harm another person
-
Public safety is threatened
Disclosure must be limited to what is necessary and to appropriate authorities.
Examples:
-
A patient threatens to assault a partner
-
A mentally unstable patient expresses intent to self-harm
-
A patient with active communicable disease refuses to follow infection control precautions
4.2 Disclosure Required by Law
Certain laws override confidentiality. These include:
-
Mandatory notifications under AHPRA
-
Child protection reporting legislation
-
Court orders or subpoenas
-
Public health reporting requirements (infectious diseases, dangerous conditions)
-
Medicare or insurance audits when legally authorized
Dentists must comply with the law even if the patient objects.
4.3 Disclosure for Therapeutic Purposes
Information may be shared with:
-
Treating healthcare team members
-
Referring specialists
-
Laboratories when essential for treatment
These disclosures are allowed as long as they are consistent with patient care and privacy legislation.
5. Mandatory Notifications Under the National Law
Mandatory notification is a legal responsibility requiring certain practitioners to notify AHPRA if they reasonably believe another health practitioner has engaged in notifiable conduct.
This applies to:
-
Dentists
-
Dental specialists
-
Dental hygienists
-
Dental therapists
-
Dental prosthetists
-
Employers
-
Education providers
5.1 Purpose of Mandatory Notification
The purpose is patient safety, not punishment. It ensures early identification of risks and prevents harm.
Mandatory notifications are governed by the Health Practitioner Regulation National Law (as in force in each state and territory).
5.2 The Threshold: “Reasonable Belief”
A “reasonable belief” must be:
-
Based on observable facts
-
Supported by objective evidence
-
More than suspicion or rumor
A practitioner is not required to investigate beyond their professional relationship with the individual but cannot ignore clear evidence.
6. Categories of Notifiable Conduct
AHPRA defines four categories of notifiable conduct. These are essential knowledge for ADC examinations and Australian dental practice.
6.1 Impairment
Impairment is defined as a condition—physical or mental—that detrimentally affects a practitioner’s ability to perform their work safely.
Sources of impairment:
-
Mental illness (untreated depression, psychosis)
-
Physical impairments limiting procedural capability
-
Substance dependence
-
Neurological conditions
-
Cognitive impairment due to illness or aging
Not every diagnosis is an impairment. The key question is:
Does the condition pose a substantial risk to the public?
Examples requiring notification:
-
A dentist with severe depression who cannot concentrate during procedures
-
A therapist with tremors affecting hand skills
-
A practitioner with substance addiction practicing unsafely
Examples that do not necessarily require notification:
-
A practitioner receiving appropriate treatment and practicing safely
-
A practitioner taking leave due to illness and not treating patients until recovery
6.2 Intoxication While Practicing
Intoxication from alcohol or drugs while treating patients is an immediate and serious threat to safety.
Examples of notifiable situations:
-
Dentist performing extractions while smelling of alcohol
-
Practitioner administering anesthesia under the influence of cannabis
-
Staff observing impaired coordination or slurred speech in a treating dentist
The requirement applies not only to illicit drugs but also:
-
Prescription medications
-
Over-the-counter sedatives
-
Abuse of nitrous oxide
6.3 Significant Departure from Professional Standards
This includes conduct that:
-
Is substantially below accepted standards
-
Places the public at risk
-
Involves reckless disregard for safety
Examples:
-
Performing unnecessary or fraudulent procedures
-
Reusing single-use items
-
Failing to maintain infection control despite reminders
-
Practicing outside one’s scope without competence
-
Using unregistered or illegally imported materials
Non-examples (not mandatory notification):
-
Differences in clinical opinion
-
Minor practice variations
-
Genuine errors without risk to the public
6.4 Sexual Misconduct
Sexual misconduct in healthcare includes:
-
Inappropriate sexual contact
-
Grooming behavior
-
Sexualized comments
-
Exploiting the patient–practitioner relationship
-
Inappropriate physical examinations without chaperone or consent
This is a zero-tolerance area. Any reasonable belief of sexual misconduct requires mandatory notification.
7. Who Must Report and When
7.1 Registered Health Practitioners
Must report when:
-
They form a reasonable belief of notifiable conduct
-
The practitioner is a colleague or supervisor
-
The conduct occurred in the context of professional practice
7.2 Employers
Must notify if a registered practitioner’s conduct places the public at risk.
7.3 Education Providers
Must report impairments that may place students at risk when they are participating in clinical training.
8. Exceptions to Mandatory Notification
Some situations exempt the practitioner from mandatory notification.
8.1 Treating Practitioner Exception
Healthcare providers who are treating the practitioner (e.g., psychiatrist treating a dentist with depression) may be exempt unless there is a substantial risk of harm to the public.
8.2 Reasonable Steps Already Taken
If the risk has already been controlled, for example:
-
Practitioner has ceased practice
-
Practitioner has been removed from clinical duties
-
Employer has taken corrective action
9. Process of Notification
9.1 How to Notify
Notification is made to:
-
AHPRA (online or phone)
-
The Dental Board of Australia (through AHPRA)
9.2 Content of a Notification
Include:
-
Practitioner’s details
-
Description of conduct
-
Evidence or observations
-
Impact on patient safety
-
Dates and times
Notifications must be factual, objective, and free of personal judgments.
9.3 AHPRA Response
AHPRA may:
-
Assess and triage the notification
-
Request more information
-
Initiate an investigation
-
Impose interim restrictions
-
Refer to a performance or health panel
-
Take no further action if not substantiated
10. Child Safety and Mandatory Reporting
Child protection laws in Australia operate at the state and territory level. Dentists are mandatory reporters in every jurisdiction, either explicitly (named in legislation) or implicitly (as registered health practitioners).
10.1 When Must a Dental Practitioner Report?
A mandatory report must be made when a practitioner suspects on reasonable grounds that a child is:
-
Being abused
-
At risk of abuse
-
Neglected
-
Exposed to family violence
-
Suffering physical, emotional, or psychological harm
-
Sexually abused or exploited
And when the suspicion is formed in the course of their professional work.
10.2 Signs Relevant to Dental Practice
Dentistry is uniquely positioned to detect craniofacial injuries associated with abuse.
Common indicators:
-
Bruising or marks on head or face
-
Torn frenulum in infants
-
Jaw fractures inconsistent with history
-
Bite marks
-
Unexplained dental trauma
-
Delay in seeking treatment for serious facial injury
-
Repeated injuries over time
Behavioral signs:
-
Fearfulness around caregivers
-
Withdrawn or anxious behavior
-
Minimizing or contradicting explanations

16. Conclusion
Ethics and mandatory notification responsibilities are not theoretical constructs—they are daily realities of Australian dental practice. Upholding these standards ensures patient safety, maintains public trust, supports the reputation of the profession, and protects practitioners from legal and regulatory consequences.
Dentists must be vigilant about consent, confidentiality, and legal obligations, especially in the areas of impaired colleagues, intoxication, misconduct, and child protection. Applying these obligations consistently and correctly is essential for compliant, safe, and ethical dentistry.

Mock Test on Ethics & Mandatory Notifications in Australian Dental Practice
Mock Test 554
Dental Emergencies-Ludwig angina
Diagnostic Algorithm for Rapidly
Progressive Submandibular Swelling
1. Initial Clinical Presentation
Symptoms: Rapidly
increasing swelling, fever, dysphagia (difficulty swallowing saliva).
Signs: Firm
induration extending to submandibular area, intraoral swelling, grossly carious
molar.
Airway status: Patient
can maintain airway but cannot tolerate oral fluids.
2. Key Decision Points
Airway assessment first:
Is airway
compromised? (stridor, drooling, inability to lie flat, desaturation).
If yes →
emergency airway management.
If no →
proceed with infection evaluation.
Localization of swelling:
Right-sided,
firm, indurated, extending to submandibular space.
Buccal
vestibular swelling intraorally.
Uvula
midline (no peritonsillar abscess).
3. Source Identification
Dental origin: Grossly
carious lower right second molar.
Pathway:
Infection spreads from molar roots → submandibular space → risk of bilateral
spread (Ludwig’s angina).
4. Differential Diagnosis
Peritonsillar
abscess (ruled out: uvula midline).
Parapharyngeal
abscess (would cause medial bulging of pharyngeal wall).
Cellulitis
vs abscess (firm induration suggests cellulitis stage).
5. Red Flag Features
Fever
(systemic involvement).
Dysphagia
(difficulty swallowing saliva).
Rapid
progression.
Submandibular
induration.
Dental
source.
6. Diagnosis
Likely:
Odontogenic infection spreading into submandibular space → early Ludwig’s angina.
Simplified Algorithm Flow
Patient presents with facial swelling + fever ↓
Check airway →
compromised? → secure airway immediately ↓
Examine swelling → location, induration, intraoral findings ↓
Identify source →
dental, tonsillar, salivary gland ↓
Rule out differentials (peritonsillar abscess, parapharyngeal abscess) ↓
Confirm odontogenic spread → submandibular space involvement ↓
Diagnosis: Ludwig’s angina (early stage)

Infection Prevention and Control
Revision Notes 5 Infection Prevention and Control
High-Yield Revision Note for ADC Part 1 Candidates
Infection Prevention and Control (IPC) is a core requirement for safe dental practice in Australia and a major topic in the ADC Part 1 examination. IPC protects patients, practitioners, staff, and the community from transmission of infectious diseases. ADC exam questions commonly test regulatory requirements, sterilisation processes, Standard Precautions, clinical judgement, and legal obligations related to IPC.
This note summarises essential knowledge for high-performance exam preparation.
1. Regulatory Framework for IPC in Australian Dentistry
IPC in dental practice is governed by the following documents and regulations:
1. Dental Board of Australia (DBA) – Guidelines for Infection Prevention and Control
Defines mandatory expectations for every registered dental practitioner.
All practitioners must be familiar with and strictly follow these guidelines.
2. NHMRC Australian Guidelines for the Prevention and Control of Infection in Healthcare
Sets national evidence-based standards for IPC across healthcare facilities.
3. AS/NZS 4815 or AS/NZS 4187
Standards for reprocessing reusable instruments, depending on practice complexity.
4. State/Territory Public Health Legislation
Covers reportable diseases, clinical waste, steriliser validation, radiation use, and practice audits.
5. Legal obligations
Failure in IPC can result in:
AHPRA notifications
Disciplinary action
Fines, suspension, or deregistration
Practice closure in severe breaches
2. Chain of Infection (High-Yield Concept)
The chain of infection involves:
Infectious agent
Reservoir
Portal of exit
Mode of transmission
Portal of entry
Susceptible host
IPC aims to break this chain through hygiene, sterilisation, environmental controls, PPE, and safe work practices.
This concept forms the theoretical basis for exam questions.
3. Standard Precautions (Core IPC Concept)
Standard Precautions apply to every patient, regardless of infection status.
They are the minimum infection control measures.
A. Hand Hygiene
Most effective IPC measure. Required:
Before/after contact with patient
After glove removal
After touching contaminated surfaces
Alcohol-based hand rub is preferred unless hands are visibly soiled.
B. Personal Protective Equipment (PPE)
Includes gloves, masks, protective eyewear, face shields, gowns/aprons.
Rules:
Gloves: single-use only (never wash or reuse)
Masks: discard when moist; do not reuse
Eye protection: clean between patients
Gowns: use when splash risk exists
C. Respiratory Hygiene & Cough Etiquette
Provide masks, tissues, and hand hygiene opportunities in waiting area.
D. Sharps Safety
Use single-hand scoop technique if recapping
Never pass sharps hands-to-hands
Dispose immediately into puncture-proof sharps container
E. Environmental Cleaning
Two categories:
Clinical contact surfaces (contaminated frequently)
→ Clean + disinfect between patientsHousekeeping surfaces
→ Routine cleaning
Use hospital-grade disinfectants listed on the ARTG (Therapeutic Goods Administration).
F. Aseptic Technique
Maintain asepsis during procedures involving:
Extractions
Surgery
Periodontal therapy
Endodontic canal entry
Minimise contamination by using sterile instruments, dry fields, and careful handling.
4. Transmission-Based Precautions
Applied in addition to Standard Precautions for certain infections.
A. Airborne Precautions
For TB, measles, chickenpox.
Measures:
N95/P2 respiratory protection
Minimise aerosol-generating procedures
Adequate room ventilation
B. Droplet Precautions
For influenza, pertussis, mumps.
Measures:
Surgical masks
Physical distancing
Patient separation in waiting room
C. Contact Precautions
For MRSA, VRE, C. difficile.
Measures:
Gloves + gown
Enhanced surface disinfection
Dedicated equipment
5. Instrument Reprocessing – High-Yield Exam Topic
Reusable dental instruments must undergo a validated sterilisation process.
A. Cleaning (critical step)
Removes organic matter. Methods:
Manual cleaning (least preferred)
Ultrasonic cleaning
Washer-disinfector
B. Inspection
Check for cleanliness, damage, rust, corrosion.
C. Packaging
Sterilisation pouches or wraps
Label with cycle number, date, operator initials
Include chemical indicators
D. Sterilisation (Steam Autoclave)
Requirements:
Correct temperature (121–134°C)
Correct cycle type and holding time
Mechanical monitoring
External + internal chemical indicators
Biological indicators (weekly or practice-specific requirement)
E. Cooling and Storage
Packs must be dry before removal
Store in clean, dust-free areas
Do not use compromised (wet/torn) packs
F. Traceability
Maintain steriliser logs including:
Cycle parameters
Results of tests (Helix/Bowie-Dick)
Load identification
Steriliser servicing schedules
Single-use items
Must never be reused, cleaned, or sterilised.
This is a frequent ADC exam trap.
6. Dental Unit Waterlines (DUWLs)
Biofilm can contaminate water lines.
Key points:
Flush lines at start of day and between patients
Maintain water quality <500 CFU/mL
Use sterile water for surgical irrigation
7. Airborne Risk Reduction During Clinical Care
Aerosol-generating procedures carry high transmission risk.
Risk reduction strategies:
High-volume evacuation
Rubber dam
Pre-procedural mouth rinses
HEPA filtration (optional)
Adequate room ventilation
AGPs require heightened PPE awareness.
8. Exposure Management (Sharps, Blood, Body Fluids)
If exposure occurs:
Steps:
Immediate washing with soap/water
Encourage bleeding from puncture (do NOT squeeze)
Rinse splashes to eyes with saline
Notify supervisor and document
Assess risk (pathogen + injury type)
Seek medical attention immediately
Initiate PEP (post-exposure prophylaxis) if required
Hepatitis B immunisation
Mandatory for all dental clinicians.
Must maintain documentation of seroconversion (anti-HBs titre).
9. Handling of Sterile and Clean Items
Sterile items
Must not be stored near sinks or contaminated zones
Must not be used if packaging compromised
Open package immediately before patient care
Clean items
Must be separated from contaminated items
Must not enter the dirty reprocessing area
Zoning (clean, dirty, sterile) is critical for compliance.
10. Environmental and Waste Management
Waste categories:
General waste → normal bin
Clinical/infectious waste → yellow bin
Sharps → dedicated sealed sharps container
Cleaning protocols
Develop written cleaning schedules
Use correct detergents and disinfectants
11. Outbreak Response and Transmission Risk
Practices must have protocols for:
Patient triage
Staff illness management
Isolation or deferral of symptomatic patients
Enhanced cleaning
Reporting communicable disease when required by law
12. Legal and Professional Accountability for IPC
IPC failures may result in:
AHPRA notification
Mandatory notification if conduct places public at substantial risk (e.g., reusing single-use items)
DBA audits
Conditions or suspension from practice
Practice closure (public health orders)
Common high-risk breaches:
Not reprocessing handpieces correctly
Reusing single-use items
Inadequate sterilisation documentation
Contaminated waterlines
Sharps mismanagement
13. High-Yield Exam Points for ADC Part 1
Memorise the following for rapid recall:
✔ Standard Precautions apply to ALL patients
✔ Hand hygiene is the most effective infection control measure
✔ Do NOT reuse single-use devices
✔ Handpieces must be heat-sterilised after every patient
✔ Autoclave validation must be documented
✔ Torn or wet sterilisation pouches = unsterile
✔ Sharps containers must be puncture-resistant and replaced when ¾ full
✔ Transmission-based precautions supplement Standard Precautions
✔ Use sterile water for surgical irrigation
✔ Report sharps injuries immediately and follow PEP protocol
✔ Hepatitis B immunity documentation required
✔ Reprocessing steps: cleaning → inspection → packaging → sterilisation → drying → storage
✔ Chain of infection forms the theoretical basis of IPC
Conclusion
Infection Prevention and Control is a legally enforceable, safety-critical component of dental practice in Australia. ADC Part 1 candidates must understand both the scientific principles and the regulatory expectations around sterilisation, Standard Precautions, transmission-based precautions, environmental controls, and post-exposure management. Mastery of IPC concepts strengthens clinical reasoning, protects patient safety, and prepares candidates thoroughly for regulatory-style exam questions.
