9.5 Professional Ethics, Jurisprudence & Dental Hygiene Practice Acts
Key Takeaways Explain This Topic AI
The ADHA Code of Ethics establishes 7 core values: Autonomy, Confidentiality, Societal Trust, Nonmaleficence, Beneficence, Justice, and Veracity.
Malpractice (professional negligence) requires proving all 4 Ds: Duty, Dereliction (breach of duty), Direct cause, and Damages.
Battery is an intentional tort defined as unpermitted, offensive physical contact without valid consent (e.g., treating a tooth over explicit patient refusal).
Assault is an intentional act that creates reasonable apprehension of imminent harmful contact, without requiring actual physical contact.

9.5 Professional Ethics, Jurisprudence & Dental Hygiene Practice Acts
Dental hygiene practice is governed by moral principles, professional ethical codes, legal statutes, and state administrative practice acts. Dental hygienists must possess a comprehensive understanding of ethical values and legal frameworks to navigate complex clinical dilemmas, protect patient rights, and maintain professional licensure.
The ADHA Code of Ethics: 7 Core Values
The American Dental Hygienists' Association (ADHA) Code of Ethics establishes seven core values that define the ethical responsibilities of dental hygienists toward patients, colleagues, and society. Autonomy (Self-Determination) ➔ Confidentiality (Privacy) ➔ Societal Trust (Public Bond)
- ➔ Nonmaleficence (Do No Harm) ➔ Beneficence (Do Good) ➔ Justice (Fairness) ➔ Veracity (Truthfulness)
- 1. Autonomy (Individual Autonomy & Self-Determination)
Definition : Patients have the moral and legal right to full self-determination. They possess the right to make independent decisions regarding their healthcare after receiving full disclosure of diagnostic findings, treatment options, potential risks, benefits, and alternatives.
Clinical Application : Respecting a competent adult patient's informed choice to accept or refuse recommended treatment (Informed Consent / Informed Refusal), even if the clinician disagrees with the patient's decision.
2. Confidentiality
Definition : The ethical obligation to hold in confidence all personal, medical, and dental information entrusted to the clinician by the patient or contained within the health record.
Clinical Application : Refraining from discussing patient cases outside of direct clinical consultation, safeguarding paper and electronic records, and adhering to HIPAA regulations.
3. Societal Trust
Definition : Maintaining public confidence in the dental hygiene profession through exemplary ethical behavior, specialized clinical competence, and dedication to public welfare.
Clinical Application : Demonstrating integrity and professional demeanor, ensuring that the public bond between society and the dental hygiene profession remains unbroken.
4. Nonmaleficence ("First, Do No Harm")
Definition : The fundamental obligation to avoid causing harm, injury, or unnecessary risk to patients ( primum non nocere ).
Clinical Application : Maintaining strict clinical competence, adhering to universal infection control, taking accurate medical histories to prevent adverse drug reactions, and knowing when to refer complex cases beyond one's scope of practice.
5. Beneficence
Definition : The active promotion of human well-being, health, and safety through preventive healthcare services and community health promotion.
Clinical Application : Delivering high-quality, evidence-based preventive care; participating in community dental health screenings; engaging in actions that actively benefit the patient's overall health.
6. Justice (Fairness)
Definition : Providing fair, equitable, and non-discriminatory care to all individuals regardless of race, age, gender, socioeconomic status, disability, or health status.
Clinical Application : Treating all patients with equal respect and clinical diligence; advocating for equal access to oral healthcare services within the community.
7. Veracity (Truthfulness)
Definition : The obligation to tell the truth and uphold complete honesty in all professional communications with patients, colleagues, and regulatory bodies.
Clinical Application : Providing accurate diagnostic information, avoiding deceptive fee billing, fully disclosing potential treatment complications, and never misleading a patient.
Jurisprudence & State Dental Hygiene Practice Acts
Jurisprudence is the philosophy or science of law. In dental hygiene, state practice acts serve as the statutory legal framework enacted by state legislatures to protect the public from incompetent or unethical practitioners.
Statutory Levels of Supervision
State Dental Hygiene Practice Acts define specific supervisory levels governing dental hygiene practice:
Supervision Level Presence of Dentist Required? Prior Diagnosis / Authorization Needed? Inspection Before Dismissal?
Direct Supervision YES (Physically present in office) YES (Dentist diagnoses and authorizes) YES (Dentist inspects before patient leaves)
Indirect Supervision YES (Physically present in office) YES (Dentist diagnoses and authorizes) NO (Inspection before dismissal not required)
- General Supervision NO (Need NOT be on premises) YES (Dentist has authorized procedures) NO
- Direct Access / Unsupervised NO (Need NOT be on premises) NO (Hygienist initiates care independently) NO
- Civil Law: Contract Law & Patient Abandonment
Civil law addresses legal disputes between private individuals or entities. Within civil law, Contract Law governs enforceable agreements between providers and patients.
Breach of Contract & Patient Abandonment
Breach of Contract : Occurs when either party fails to fulfill obligations set forth in a legal contract (expressed or implied).
Patient Abandonment : A specific breach of contract occurring when a dentist or dental hygienist terminates the professional provider-patient relationship without giving reasonable notice or providing an opportunity to secure another qualified care provider , while the patient still requires ongoing dental care.
Legal Requirements to Avoid Abandonment : The practice must provide formal written notice (sent via certified mail with return receipt), state a specific termination date (typically 30 days notice), offer emergency dental coverage during the transition period, and offer to transfer copies of dental records to the new provider.
Civil Law: Tort Law (Unintentional vs. Intentional Torts)
A Tort is a civil wrong (other than a breach of contract) committed against a person or property that results in harm, for which the legal system provides a remedy in the form of monetary damages. Tort Law ➔ Unintentional Torts (Negligence & Malpractice) ➔ Requires 4 Ds
- Tort Law ➔ Intentional Torts (Battery, Assault, Defamation, Invasion of Privacy)
- Unintentional Torts: Negligence versus Malpractice
Negligence : The failure to exercise the degree of care that a reasonably prudent person (or clinician) would exercise under similar circumstances, resulting in unintended harm.
Malpractice (Professional Negligence) : A specialized form of negligence committed by a licensed professional who fails to adhere to the accepted standard of care. To successfully prove a malpractice claim in a court of law, the plaintiff must prove all four elements (The 4 Ds of Malpractice) by a preponderance of evidence:
Duty : A legal provider-patient relationship existed.
Dereliction (Breach of Duty) : The clinician failed to comply with the accepted standard of care.
Direct Cause (Causation) : The clinician's breach of duty was the direct and proximate cause of the injury.
Damages : Actual physical, financial, or emotional injury resulted to the patient.
Intentional Torts: Battery versus Assault
Intentional torts involve deliberate, intentional acts committed against a person or property.
Intentional Tort Legal Definition Clinical Dental Hygiene Example
Battery Unpermitted, intentional, harmful, or offensive physical contact with another person without valid consent Performing scaling or fluoride treatment on a patient who explicitly refused; treating the wrong tooth or quadrant
Assault An intentional act that creates a reasonable apprehension of imminent harmful or offensive contact (no physical touching required) Raising a hand threateningly or verbally threatening a fearful pediatric patient with physical restraint
Defamation Making false statements that damage a person's reputation Libel (written false statements in chart notes/emails); Slander (spoken false statements to third parties)
False Imprisonment Intentional restraint of a person's freedom of movement without legal justification Refusing to lower the dental chair or blocking the doorway when a competent patient demands to leave
