Question 1Montana Dental Practice Act: scope, definitions, and licensing framework

Under the Montana Dental Practice Act, which person is authorized to practice dentistry in Montana?

  1. A person trained as a dental assistant with five years of chairside experience
  2. A person who has completed an accredited dental program but not yet applied
  3. A person licensed as a dentist in another state who advertises locally
  4. A person holding a current Montana dental license issued by the Board of Dentistry Correct answer.

Explanation

The Act makes the practice of dentistry lawful only for individuals who hold a valid Montana license issued by the Board of Dentistry. Graduation alone does not confer practice authority, and out-of-state licensure does not transfer automatically. Advertising or offering services without a Montana license is unlicensed practice.

Question 2Montana Dental Practice Act: scope, definitions, and licensing framework

What is the primary statutory purpose of the Montana Board of Dentistry?

  1. To negotiate insurance reimbursement rates with carriers
  2. To set fee schedules for dental procedures across Montana
  3. To protect the public health, safety, and welfare through regulation of dental practice Correct answer.
  4. To promote the financial interests of licensed dentists in the state

Explanation

The Board exists to safeguard the public by regulating who may practice dentistry and how practice occurs. Its authority flows from the state's police power to protect health, safety, and welfare. It does not set prices or negotiate with insurers, which are outside its statutory mandate.

Question 3Montana Dental Practice Act: scope, definitions, and licensing framework

A dental hygienist in Montana wishes to provide services to patients. Which statement best describes the licensing framework for dental hygienists under the Act?

  1. Hygienists practice without any license because their work is delegated by dentists
  2. Hygienists are licensed by the Board and practice within a defined scope, often under dentist supervision or authorization Correct answer.
  3. Hygienists are licensed as dentists once they pass a clinical examination
  4. Hygienists are certified by a private professional association rather than the state

Explanation

The Act establishes dental hygiene as a separately licensed profession regulated by the Board, with its own scope of practice. Hygienists do not practice by delegation alone, and they are not licensed as dentists. Private associations do not confer state practice authority.

Question 4Montana Dental Practice Act: scope, definitions, and licensing framework

Which of the following activities falls within the statutory definition of practicing dentistry?

  1. Sterilizing instruments in the office autoclave
  2. Scheduling patient appointments at the front desk
  3. Taking a dental radiograph for diagnostic purposes Correct answer.
  4. Ordering dental supplies from a vendor

Explanation

Taking radiographs for diagnosis is part of diagnosing and treating conditions of the oral cavity, which the Act reserves to licensed practitioners. Instrument sterilization, scheduling, and purchasing are supportive tasks that do not themselves constitute the practice of dentistry. The diagnostic purpose is what places radiography within the dental scope.

Question 5Montana Dental Practice Act: scope, definitions, and licensing framework

A person not licensed in Montana performs a full-mouth prophylaxis for payment. Under the Act, this conduct is best characterized as which of the following?

  1. Permissible because prophylaxis is not a regulated service
  2. Permissible if the person holds a certificate from an online course
  3. Permissible because the patient consented to the service
  4. Unlicensed practice of dentistry, subject to Board and legal action Correct answer.

Explanation

Performing prophylaxis for compensation without a Montana license constitutes unlicensed practice, which the Board may enjoin and the state may prosecute. Patient consent does not cure the absence of a license. Online certificates and lay opinion do not create practice authority.

Question 6Montana Dental Practice Act: scope, definitions, and licensing framework

Which body has statutory authority to adopt rules implementing the Montana Dental Practice Act?

  1. The Montana Board of Dentistry Correct answer.
  2. The county health department in which the licensee works
  3. The American Dental Association
  4. The Montana Dental Hygienists' Association

Explanation

The Board of Dentistry is the administrative body empowered to adopt rules that carry out the Act. Professional associations are private organizations without rulemaking authority. Local health departments and national associations do not govern Montana licensure.

Question 7Montana Dental Practice Act: scope, definitions, and licensing framework

A dentist licensed in Montana moves to another state and wishes to continue treating Montana patients remotely. Which principle governs whether this is permissible?

  1. A Montana license authorizes practice anywhere because licensure is national
  2. Practice authority depends on the location of the patient and the requirements of the jurisdiction where the patient is located Correct answer.
  3. Remote care is unregulated and requires no licensure
  4. A Montana license remains valid indefinitely as long as the dentist does not relocate the office

Explanation

Licensure is tied to the jurisdiction where the patient receives care, so a dentist must satisfy the requirements of the state where the patient is located. A Montana license alone does not authorize practice into another state. Remote care does not escape licensure.

Question 8Montana Dental Practice Act: scope, definitions, and licensing framework

Which of the following is a typical requirement for initial dental licensure in Montana?

  1. Residency in the county where the office is located
  2. Membership in a national dental association
  3. Passing a recognized clinical and written examination and meeting education requirements Correct answer.
  4. Purchase of a minimum amount of malpractice insurance

Explanation

Initial licensure generally requires graduation from an accredited program plus passing recognized examinations accepted by the Board. Association membership is voluntary, and county residency is not a licensure condition. Malpractice insurance may be prudent but is not the statutory licensing criterion described here.

Question 9Montana Dental Practice Act: scope, definitions, and licensing framework

A licensee's Montana dental license lapses for failure to renew. What is the licensee's status regarding practice?

  1. The licensee may continue practicing while renewal paperwork is processed
  2. The licensee may practice but must display a lapsed certificate
  3. The licensee may not practice until the license is reinstated according to Board rules Correct answer.
  4. The licensee may practice only on patients of record

Explanation

Once a license lapses, the holder loses the legal authority to practice until reinstatement under Board rules, which may include fees or conditions. Treating existing patients does not preserve authority. Administrative processing delays do not create interim practice rights.

Question 10Montana Dental Practice Act: scope, definitions, and licensing framework

The term "supervision" as used in the Montana Dental Practice Act most closely refers to which concept?

  1. The Board's review of continuing education transcripts
  2. The physical presence of a receptionist during treatment
  3. A written contract between the dentist and the patient
  4. The dentist's oversight and responsibility for services delegated to auxiliary personnel Correct answer.

Explanation

Supervision describes the dentist's oversight of and accountability for care delegated to dental auxiliaries, with the required degree of oversight set by rule. It is a professional responsibility tied to delegated services. Clerical presence, CE review, and patient contracts are unrelated to the concept.

Question 11Montana Dental Practice Act: scope, definitions, and licensing framework

Which statement accurately describes the scope of practice for a Montana dental hygienist?

  1. Hygienists may diagnose and prescribe treatment independently of any dentist
  2. Hygienists provide services within the dental hygiene scope defined by statute and Board rules, including preventive and therapeutic services Correct answer.
  3. Hygienists may perform any procedure a dentist performs if the dentist is on site
  4. Hygienists may perform restorative procedures without additional authorization

Explanation

Dental hygiene scope is defined by statute and Board rules and centers on preventive and therapeutic services such as prophylaxis and periodontal therapy. It does not mirror the full dental scope. Restorative and diagnostic-prescriptive acts require separate authority and are not automatic.

Question 12Montana Dental Practice Act: scope, definitions, and licensing framework

A dentist delegates a task to a dental assistant. Who retains responsibility for the patient's care?

  1. The patient, who accepted the delegated service
  2. The Board, which assumes responsibility for all delegated care
  3. The dental assistant, because the assistant performed the task
  4. The supervising dentist, because delegation does not transfer professional responsibility Correct answer.

Explanation

Delegation assigns performance of a task but the supervising dentist remains professionally responsible for the patient's care and for proper delegation. Responsibility is not shifted to the assistant or the patient. The Board regulates practice but does not assume clinical responsibility.

Question 13Montana Dental Practice Act: scope, definitions, and licensing framework

Which of the following best describes the Board's authority over license discipline?

  1. The Board must refer all complaints to the courts and cannot act itself
  2. The Board may revoke, suspend, or place conditions on a license for cause after proceedings consistent with due process Correct answer.
  3. The Board may discipline only dentists, not hygienists
  4. The Board may only issue written warnings

Explanation

The Board may impose a range of sanctions, including revocation, suspension, probation, and conditions, following procedures that satisfy due process. It is not limited to warnings and does act on complaints directly. Its jurisdiction extends to all licenses it issues, including dental hygiene.

Question 14Montana Dental Practice Act: scope, definitions, and licensing framework

A patient alleges that a hygienist practiced outside the hygiene scope. Which sequence best reflects the regulatory process?

  1. The patient must sue in court before the Board may review the matter
  2. The association for hygienists conducts the investigation and sanctions the member
  3. The hygienist's employer alone decides the outcome and the Board plays no role
  4. The Board receives and investigates the complaint, then may hold a hearing and impose discipline if warranted Correct answer.

Explanation

Complaints are filed with the Board, which investigates and, where cause appears, proceeds to a hearing and possible discipline. The employer's internal action does not displace Board authority. A civil suit is a separate remedy, and professional associations do not impose state sanctions.

Question 15Montana Dental Practice Act: scope, definitions, and licensing framework

Under the Act, which individual would be required to obtain a Montana dental license before providing patient care?

  1. A dentist who recently completed an accredited program and intends to treat patients Correct answer.
  2. A vendor demonstrating equipment to staff
  3. A lecturer teaching a continuing education course without patient contact
  4. A dental student observing procedures without touching the patient

Explanation

Anyone who will diagnose or treat patients must hold a Montana license; a new graduate must be licensed before providing care. Observation without participation, equipment demonstration, and classroom teaching without patient contact do not constitute practice. The key is whether the person will actually deliver dental care.

Question 16Montana Dental Practice Act: scope, definitions, and licensing framework

What is the significance of the term "practice of dental hygiene" in the Act?

  1. It applies only to hygienists employed in public health settings
  2. It is merely a descriptive label with no regulatory effect
  3. It defines the services hygienists may perform and the conditions under which they may perform them Correct answer.
  4. It authorizes hygienists to perform any task a dentist delegates

Explanation

The statutory definition of dental hygiene establishes the boundaries of the profession and the conditions of practice. It is operative, not merely descriptive, and applies across employment settings. It does not open the entire dental scope to delegation.

Question 17Montana Dental Practice Act: scope, definitions, and licensing framework

A Montana licensee is convicted of a crime involving fraud. How does the Act typically treat such a conviction?

  1. It may constitute grounds for discipline because it relates to the licensee's fitness and trustworthiness Correct answer.
  2. It has no bearing because licensure is separate from criminal law
  3. It requires the Board to increase the licensee's scope of practice
  4. It automatically voids the license without any Board proceeding

Explanation

Certain convictions, particularly those bearing on honesty or fitness, may serve as grounds for Board discipline. The Board evaluates the conduct through its process rather than applying automatic revocation. Criminal and licensing systems operate in parallel.

Question 18Montana Dental Practice Act: scope, definitions, and licensing framework

Which of the following is most consistent with the Act's treatment of continuing education for license renewal?

  1. Licensees must complete required continuing education as a condition of renewal Correct answer.
  2. Continuing education hours may be replaced by years of experience
  3. Continuing education is optional for all licensees
  4. Continuing education is required only for dentists, not hygienists

Explanation

Renewal is conditioned on completing the continuing education required by Board rules, which keeps licensees current. The requirement applies to licensed professions regulated by the Board, including dental hygiene. It is not satisfied merely by years in practice unless a rule provides otherwise.

Question 19Montana Dental Practice Act: scope, definitions, and licensing framework

A dentist wishes to have a hygienist perform a procedure that is not listed in the hygiene scope but is within the dentist's own scope. What is the correct analysis?

  1. Delegation is permitted only if the Act or Board rules authorize the hygienist to perform that procedure Correct answer.
  2. The hygienist may perform it if no dentist is available
  3. The dentist may delegate any procedure because the dentist holds a full license
  4. The hygienist may perform it if the patient signs a consent form

Explanation

A dentist's broad scope does not automatically transfer through delegation; the Act and Board rules define what may be delegated to each auxiliary type. Patient consent and dentist unavailability do not expand the hygienist's authorized scope. The controlling question is whether the rule permits the delegation.

Question 20Montana Dental Practice Act: scope, definitions, and licensing framework

Which of the following best describes how the Act defines the relationship between a dentist and a dental hygienist in most practice settings?

  1. The hygienist may direct the dentist's treatment decisions
  2. The hygienist practices completely independently with no relationship to a dentist
  3. The hygienist provides hygiene services within a framework that generally involves dentist supervision or authorization Correct answer.
  4. The hygienist functions as the dentist's legal employer

Explanation

The Act generally frames hygiene practice around dentist supervision or authorization, with the specific degree set by statute and rule. It does not create complete independence in all settings, nor does it invert the professional hierarchy. Employment arrangements are separate from scope and supervision requirements.

Question 21Montana Dental Practice Act: scope, definitions, and licensing framework

Which statement correctly describes the effect of Board rules on the statutory Act?

  1. Rules implement and interpret the statute but cannot exceed the authority the statute grants Correct answer.
  2. Rules apply only to dentists and not to hygienists
  3. Rules replace the statute once adopted
  4. Rules may contradict the statute whenever the Board disagrees with it

Explanation

Administrative rules carry out the statute and must remain within its grant of authority; a rule that conflicts with the statute is invalid. Rules do not supersede legislation. They apply to the licensees the statute covers, including hygienists.

Question 22Montana Dental Practice Act: scope, definitions, and licensing framework

A person uses the title "dental hygienist" in Montana advertising without holding a license. What is the most accurate characterization?

  1. Permissible because a title is only descriptive
  2. Permissible if the person works in a dentist's office
  3. Permissible if the person has completed hygiene coursework
  4. A violation, because use of a protected title is restricted to licensees Correct answer.

Explanation

The Act restricts use of protected professional titles to licensed individuals, so unlicensed use of "dental hygienist" is itself a violation. Coursework and employment setting do not confer title rights. Titles signal licensure status to the public, which is why they are regulated.

Question 23Montana Dental Practice Act: scope, definitions, and licensing framework

Which of the following is the best example of a task that would ordinarily require dental licensure rather than hygiene licensure?

  1. Performing a prophylaxis on a healthy adult
  2. Providing oral health instruction to a patient
  3. Taking a bitewing radiograph as authorized
  4. Placing a permanent restoration after caries removal Correct answer.

Explanation

Preparing a tooth and placing a permanent restoration is a restorative dental procedure reserved to dentists unless a specific rule authorizes otherwise. Prophylaxis, oral health instruction, and authorized radiography fall within hygiene practice. The restorative act involves irreversible treatment and diagnosis.

Question 24Montana Dental Practice Act: scope, definitions, and licensing framework

A licensee moves from another state and seeks Montana licensure by credentials. Which statement best reflects the governing framework?

  1. The applicant must repeat dental school to qualify
  2. Any out-of-state licensee is automatically granted a Montana license
  3. Licensure by credentials is unavailable in Montana for any profession
  4. The Board applies criteria set by statute and rule to determine eligibility for licensure by credentials Correct answer.

Explanation

Licensure by credentials is governed by statutory and rule-based criteria the Board applies to evaluate an applicant's out-of-state license, experience, and standing. It is not automatic, and repeating dental school is not the mechanism. The Board determines eligibility case by case under its rules.

Question 25Montana Dental Practice Act: scope, definitions, and licensing framework

Which statement best describes the Act's approach to advertising and solicitation by licensees?

  1. Advertising is permitted but must not be false, deceptive, or misleading Correct answer.
  2. Advertising rules apply only to dentists who own their practices
  3. Advertising is permitted only in print newspapers
  4. Advertising is entirely prohibited for dental licensees

Explanation

Licensees may advertise, but the Act and rules prohibit false, deceptive, or misleading statements that could harm the public. The medium is not restricted to print. Advertising standards apply to licensees regardless of ownership status.

Question 26Montana Dental Practice Act: scope, definitions, and licensing framework

Under the Montana Dental Practice Act, which term describes the professional relationship in which a licensed dentist authorizes and remains accountable for care delivered by a dental hygienist?

  1. Independent practice
  2. Consultation
  3. Direct supervision
  4. General supervision Correct answer.

Explanation

General supervision is the framework in which a dentist authorizes hygiene services but need not be physically present while they are performed, while remaining responsible for the patient's overall care. Direct supervision requires the dentist to be physically present and evaluate the work. Independent practice and consultation do not describe delegated hygiene care.

Question 27Montana Dental Practice Act: scope, definitions, and licensing framework

A Montana dental hygienist wishes to administer local anesthesia. Which statement best reflects how the Act and Board rules address this?

  1. It requires additional training and a specific permit or certification beyond the hygiene license Correct answer.
  2. It is permitted for any licensed hygienist without further qualification
  3. It is prohibited for hygienists in all circumstances
  4. It may be performed only by a dentist and never delegated

Explanation

Local anesthesia administration by hygienists in Montana is an expanded function that depends on completing additional education and holding the required authorization from the Board. The plain hygiene license alone does not confer this authority. It is neither universally prohibited nor freely available without extra qualification.

Question 28Montana Dental Practice Act: scope, definitions, and licensing framework

Which individual is exempt from Montana dental licensure when rendering emergency care in accordance with the Act's exemption provisions?

  1. A recent graduate who has not yet passed clinical boards
  2. A licensed dentist from another state responding to a declared emergency Correct answer.
  3. A foreign-trained dentist who has not completed credentialing
  4. A dental assistant performing coronal polishing for a fee

Explanation

The Act contains limited exemptions, including emergency response by out-of-state licensees during a declared disaster or emergency. These exemptions are narrow and time-limited. Assistants, unlicensed graduates, and uncredentialed foreign-trained dentists do not fall within them.

Question 29Montana Dental Practice Act: scope, definitions, and licensing framework

A Montana hygienist is employed by a dentist and also wishes to provide hygiene services in a public health program at a school. What does the Act generally require for this arrangement?

  1. The services must be authorized under the Act's public health supervision provisions and applicable rules Correct answer.
  2. The hygienist must obtain a dentist license to bill public programs
  3. No authorization is needed because public health settings are unregulated
  4. A separate dental license is required for school-based care

Explanation

Montana law recognizes public health supervision arrangements that let hygienists deliver services in specified settings such as schools, subject to conditions set by statute and Board rule. These services are still regulated and require the appropriate authorization. Public health settings are not unregulated, and no dental license is needed for hygiene services.

Question 30Montana Dental Practice Act: scope, definitions, and licensing framework

What is the primary purpose of the Montana Board of Dentistry as established under the Dental Practice Act?

  1. To promote the financial interests of licensed dentists
  2. To represent licensees in malpractice litigation
  3. To protect the public by regulating the practice of dentistry and dental hygiene Correct answer.
  4. To set reimbursement rates for dental procedures

Explanation

The Board's statutory mission is public protection through licensure, rulemaking, and discipline of dentists and hygienists. It does not set fees for services or advocate for licensees' commercial interests. It also does not provide legal representation in malpractice suits.

Question 31Montana Dental Practice Act: scope, definitions, and licensing framework

Which of the following activities falls within the statutory definition of the practice of dentistry rather than the practice of dental hygiene?

  1. Taking dental radiographs under authorized supervision
  2. Removing calculus deposits from tooth surfaces
  3. Applying fluoride varnish to a child's teeth
  4. Diagnosing a periapical lesion and prescribing treatment Correct answer.

Explanation

Diagnosis and prescription of treatment are core dental functions reserved to licensed dentists under the Act's definition of dentistry. Scaling, fluoride application, and radiography are hygiene services that may be performed by hygienists within their scope and supervision requirements.

Question 32Montana Dental Practice Act: scope, definitions, and licensing framework

A Montana dentist wants a hygienist to place and carve a permanent amalgam restoration. How should this be analyzed under the Act?

  1. It is outside hygiene scope and must be performed by a licensed dentist Correct answer.
  2. It is permitted because the dentist authorized it in writing
  3. It is permitted if the hygienist has five years of experience
  4. It is permitted because restorative tasks are delegated by rule to hygienists

Explanation

Placing and carving permanent restorations is the practice of dentistry and cannot be delegated to a hygienist merely by dentist authorization. Delegation cannot expand the statutory scope of hygiene. Experience level and written authorization do not change this result.

Question 33Montana Dental Practice Act: scope, definitions, and licensing framework

Which statement best describes how the Act treats the title "registered dental hygienist" in Montana?

  1. Use of the title is restricted to persons holding a valid Montana hygiene license Correct answer.
  2. The title has no legal significance and is purely honorary
  3. The title may be used by students enrolled in an accredited program
  4. Any dental assistant may use the title after one year of employment

Explanation

The Act restricts the use of titles implying licensure, including registered dental hygienist, to individuals who actually hold a valid Montana license. Unlicensed use of the title is a violation subject to enforcement. Students and assistants do not acquire title rights through enrollment or employment.

Question 34Montana Dental Practice Act: scope, definitions, and licensing framework

A hygienist licensed in Montana allows her license to expire and continues seeing patients while a renewal application is pending. What is the most accurate characterization?

  1. She may practice because renewal is pending
  2. She may practice for up to 90 days after expiration
  3. She may practice if the dentist supervises directly
  4. She is practicing without a valid license and subject to discipline Correct answer.

Explanation

Practice requires a currently valid license; a pending renewal does not authorize continued practice after expiration. Practicing on an expired license exposes the hygienist to disciplinary action. Neither supervision nor a grace period cures the lapse in licensure.

Question 35Montana Dental Practice Act: scope, definitions, and licensing framework

Which of the following best describes the Act's requirement regarding informed consent before dental treatment?

  1. Consent is required only for surgical procedures
  2. The treating licensee must obtain the patient's consent after explaining the proposed treatment and alternatives Correct answer.
  3. Consent is implied whenever the patient schedules an appointment
  4. Consent may be obtained by any staff member without discussion of alternatives

Explanation

Montana law places the duty to obtain informed consent on the treating licensee, who must explain the proposed treatment, risks, and alternatives. Consent is not implied merely by scheduling. It applies broadly to treatment, not only to surgery, and cannot be delegated to untrained staff without discussion.

Question 36Montana Dental Practice Act: scope, definitions, and licensing framework

A Montana licensee fails to report a change of address to the Board as required. What is the most likely regulatory consequence?

  1. The license is automatically revoked without a hearing
  2. The licensee must retake the clinical examination
  3. No consequence exists because address changes are optional
  4. The Board may take disciplinary action for failure to comply with reporting requirements Correct answer.

Explanation

Licensees must keep the Board informed of a current address so official notices can be delivered. Failure to comply with reporting requirements can support disciplinary action. Automatic revocation and re-examination are not the standard consequences for an address reporting lapse.

Question 37Montana Dental Practice Act: scope, definitions, and licensing framework

Which statement best captures the Act's approach to the corporate practice of dentistry in Montana?

  1. Any business may employ dentists to provide care without restriction
  2. Dental services must be provided through a practice owned and controlled by licensed dentists as the Act requires Correct answer.
  3. Corporations may own dental practices if they pay a registration fee
  4. Only hospitals may own dental practices

Explanation

Montana limits ownership and control of dental practices to licensed dentists, consistent with the prohibition on the corporate practice of dentistry. Non-dentist entities cannot simply employ dentists to deliver care. Neither hospital ownership nor fee payment creates a general exception.

Question 38Montana Dental Practice Act: scope, definitions, and licensing framework

A patient complains that a hygienist disclosed confidential health information without authorization. Under the Act, how is such conduct typically treated?

  1. As a criminal offense only, with no licensing consequence
  2. As permissible because dental records are public
  3. As a potential violation subject to Board investigation and discipline Correct answer.
  4. As a private matter outside the Board's jurisdiction

Explanation

Unauthorized disclosure of patient information can constitute unprofessional conduct under the Act and may be investigated and disciplined by the Board. Licensing consequences can exist alongside any other legal remedies. Dental records are not public, and confidentiality breaches are within the Board's regulatory reach.

Question 39Montana Dental Practice Act: scope, definitions, and licensing framework

Which of the following best describes the Act's treatment of a licensee who practices while impaired by alcohol or drugs?

  1. It is permitted if the licensee discloses the impairment afterward
  2. It is grounds for discipline and may lead to license suspension or conditions Correct answer.
  3. It is handled only by the employer, not the Board
  4. It is excused if the licensee has no prior violations

Explanation

Practicing while impaired is unprofessional conduct that can result in suspension, restriction, or conditions on the license, sometimes through a monitored rehabilitation agreement. A clean prior record does not excuse the conduct. The Board retains authority independent of any employer action.

Question 40Montana Dental Practice Act: scope, definitions, and licensing framework

A Montana hygienist is asked to perform a procedure that the Act assigns to dentists but that the supervising dentist insists is "close enough" to hygiene. What is the hygienist's best course of action?

  1. Perform the procedure if the patient signs a consent form
  2. Perform the procedure and document the dentist's instruction
  3. Decline to perform the procedure because scope limits cannot be waived by a supervising dentist Correct answer.
  4. Perform the procedure once and then request a rule change

Explanation

The statutory scope of hygiene is fixed by law, and a supervising dentist's instruction cannot authorize a hygienist to exceed it. Performing a dental procedure would expose the hygienist to discipline regardless of documentation or consent. The proper response is to decline and, if desired, pursue a rule change through the Board.

Question 41Scope of practice and supervision levels for dental hygienists

Under the dental hygiene scope-of-practice rules, which activity is a hygienist permitted to perform as part of the defined scope rather than as a delegated task?

  1. Administering a general anesthetic agent
  2. Extracting a mobile primary tooth
  3. Performing a prophylaxis and supragingival scaling on an adult patient Correct answer.
  4. Preparing and placing a permanent amalgam restoration

Explanation

Prophylaxis and supragingival scaling are core functions within the statutory scope of dental hygiene practice, so they do not require case-by-case delegation. Restorative placement, extractions, and general anesthesia are reserved to the dentist or other licensed providers. The distinction matters because in-scope procedures may be performed under the general supervision levels defined for hygiene, while delegated procedures require specific authorization.

Question 42Scope of practice and supervision levels for dental hygienists

A patient asks the hygienist to take a radiograph. Which statement best describes the supervision typically required for exposing dental radiographs in most jurisdictions?

  1. It is performed under the supervision level the rules assign to radiography, often general supervision with the dentist having authorized the service Correct answer.
  2. It may be done independently without any dentist involvement
  3. It requires the dentist to be on the premises and to examine the patient first
  4. It may only be performed by the dentist personally

Explanation

Radiograph exposure is generally an authorized hygiene function performed at a defined supervision level, frequently general supervision, meaning the dentist has prescribed or authorized the service though need not be present. It is not an independent act free of any dentist authorization. It also is not restricted to the dentist personally in most jurisdictions.

Question 43Scope of practice and supervision levels for dental hygienists

Which term describes the level at which the dentist has authorized the procedure and is available for consultation but is not physically present in the office?

  1. Personal supervision
  2. Direct supervision
  3. General supervision Correct answer.
  4. Indirect supervision

Explanation

General supervision means the dentist has authorized the procedure for a patient of record but is not required to be physically present. The dentist must still be reachable and the patient must be a patient of record. This differs from direct supervision, which requires the dentist's physical presence.

Question 44Scope of practice and supervision levels for dental hygienists

A hygienist is asked to provide services to a new patient who has never been examined by the dentist in the practice. Under a general supervision model, what is the key requirement before treatment?

  1. The patient must be examined by another hygienist first
  2. The patient must be a patient of record with the dentist's authorization for the service Correct answer.
  3. The hygienist must obtain a separate written consent from the state board
  4. The dentist must be physically present in the operatory

Explanation

General supervision presumes the individual is a patient of record and that the dentist has authorized the service, often following an examination or prescription. Without that established relationship and authorization, general supervision is not satisfied. Physical presence is the hallmark of direct supervision, not general supervision.

Question 45Scope of practice and supervision levels for dental hygienists

In jurisdictions that recognize an extended-function or expanded-function hygienist, which additional service is most commonly authorized after extra training and certification?

  1. Prescribing antibiotic regimens
  2. Performing orthodontic extractions
  3. Administering local anesthesia under specified supervision Correct answer.
  4. Diagnosing pulpal pathology

Explanation

Local anesthesia administration by hygienists is a common expanded function permitted after additional education, certification, and compliance with a defined supervision level. Diagnosis and prescribing remain dentist responsibilities. Extractions are surgical and not part of hygiene expanded functions.

Question 46Scope of practice and supervision levels for dental hygienists

A dentist wishes to have a hygienist perform a reversible delegated procedure that is not listed in the hygiene scope. What is the most accurate statement about delegation?

  1. Any procedure may be delegated as long as the patient consents
  2. Delegation is never permitted for any procedure outside the listed scope
  3. Delegation is permitted only if the procedure is authorized by the rules and the hygienist is competent and appropriately supervised Correct answer.
  4. Delegation is permitted whenever the dentist is in the building

Explanation

Delegation requires both statutory or regulatory authorization and demonstrated competence of the delegatee, performed at the required supervision level. Patient consent alone does not create authority to delegate. Physical proximity alone also does not authorize a procedure the rules do not permit.

Question 47Scope of practice and supervision levels for dental hygienists

Which of the following best characterizes direct supervision as applied to dental hygiene services?

  1. The dentist must be physically present in the office and evaluate the patient's condition and the work performed Correct answer.
  2. The dentist must be reachable by phone but need not be present
  3. The dentist reviews the record within 30 days
  4. The hygienist may proceed after consulting a colleague

Explanation

Direct supervision requires the dentist to be physically present in the office, to have evaluated the patient, and to be available to examine the completed work. Telephone availability describes general supervision. A delayed record review does not satisfy direct supervision.

Question 48Scope of practice and supervision levels for dental hygienists

A patient presents with moderate calculus and gingivitis. Which service is clearly within the standard hygiene scope and does not require expanded-function certification?

  1. Suturing a gingival flap
  2. Scaling and root planing for periodontal therapy Correct answer.
  3. Placement of a subgingival sustained-release antibiotic
  4. Prescribing a chlorhexidine rinse

Explanation

Scaling and root planing is a recognized periodontal therapy within hygiene practice, though some jurisdictions impose additional supervision requirements for nonsurgical periodontal therapy. Drug placement, suturing, and prescribing are not standard hygiene functions. These require dentist involvement or separate authority.

Question 49Scope of practice and supervision levels for dental hygienists

Which statement about the role of a collaborating or consulting dentist in a public health or independent hygiene setting is most accurate?

  1. The hygienist must always have the dentist on site
  2. No dentist relationship is ever required in any setting
  3. The rules may permit practice under a collaborative agreement with defined referral and consultation obligations Correct answer.
  4. The hygienist may diagnose and treatment plan independently

Explanation

Some jurisdictions allow practice in public health or limited-access settings under a collaborative agreement that specifies referral, consultation, and record requirements. This is not full independent diagnosis and treatment planning. It also does not require the dentist to be on site in every model.

Question 50Scope of practice and supervision levels for dental hygienists

A hygienist administers local anesthesia under a permit. Which supervision level is most commonly specified for this expanded function?

  1. Independent practice without dentist involvement
  2. Direct supervision with the dentist on the premises Correct answer.
  3. Self-determined supervision at the hygienist's discretion
  4. General supervision with no dentist authorization

Explanation

Local anesthesia administration is typically performed under direct supervision, requiring the dentist to be present because of the increased risk of adverse reactions. The permit also requires specific education and certification. Independent or self-determined practice is not the standard for this function.
