CERTIFICATION PREPARATION
1. A dentist is presented with a new patient who is currently under the care of another dentist for
orthodontic treatment. The patient is dissatisfied with the progress and wishes to transfer care.
What is the dentist's primary ethical and legal obligation before beginning treatment?
A. Contact the previous dentist immediately to inform them of the patient's dissatisfaction.
B. Obtain a copy of the patient's records and radiographs from the previous dentist before any
examination.
C. Request a written referral from the previous dentist before initiating any new treatment.
D. Conduct a thorough examination and diagnosis to establish a new doctor-patient relationship
before providing treatment.
Correct Answer: D. Conduct a thorough examination and diagnosis to establish a new doctor-
patient relationship before providing treatment.
Rationale: A dentist must establish a new doctor-patient relationship based on their own examination
and diagnosis before assuming care for a patient from another provider. This fulfills the standard of
care and ensures the new dentist is legally and ethically responsible for their own treatment plan.
While requesting records (B) is a best practice, it does not substitute for a new examination. Option A
is a violation of patient confidentiality and could be seen as unprofessional, and option C is not
required as a patient does not need a referral to see a dentist of their choice in most cases.
2. A licensed Texas dentist wishes to administer nitrous oxide analgesia. According to the Texas
State Board of Dental Examiners (TSBDE) rules, what is the minimum requirement for the dentist
to perform this procedure legally?
A. Completion of a board-approved course in the administration of nitrous oxide.
B. Possession of a valid Drug Enforcement Administration (DEA) registration.
C. A current certification in Advanced Cardiac Life Support (ACLS).
D. A formal arrangement with a supervising anesthesiologist.
Correct Answer: A. Completion of a board-approved course in the administration of nitrous oxide.
Rationale: Texas administrative code requires a dentist to have completed a board-approved training
course specifically for the administration and monitoring of nitrous oxide-oxygen analgesia. While a
DEA registration (B) is necessary for prescribing controlled substances, it is not the specific
requirement for using nitrous oxide. ACLS (C) is not a general requirement for nitrous oxide, and a
supervising anesthesiologist (D) is not needed for this level of inhalation analgesia.
,3. A dental hygienist is performing a prophylaxis on a patient with a known history of mitral valve
prolapse. The patient states they took their prophylactic antibiotic as prescribed by their physician.
What is the hygienist's best course of action?
A. Proceed with the prophylaxis as the patient has already taken the antibiotic.
B. Confirm the specific antibiotic, dose, and timing with the patient and document it in the chart.
C. Contact the prescribing physician to verify the antibiotic prescription.
D. Refuse to treat the patient until a written prescription is provided directly to the office.
Correct Answer: B. Confirm the specific antibiotic, dose, and timing with the patient and document
it in the chart.
Rationale: The dental hygienist should document the patient's reported antibiotic regimen, including
the drug, dose, and time taken, to ensure compliance with the current American Heart Association
(AHA) guidelines for infective endocarditis prophylaxis. Option A is insufficient because they must
verify and document. While contacting the physician (C) is not standard practice for a routine
confirmation, and refusing treatment (D) is not necessary as the patient has already taken the
medication as prescribed.
4. A dentist diagnoses a patient with a large carious lesion on tooth #19 that requires a crown.
After preparing the tooth and taking an impression, the dentist leaves the room while the dental
assistant pours the model. Upon returning, the dentist notices the assistant did not mix the
gypsum product according to the manufacturer's instructions. Which of the following is the
dentist's most appropriate action?
A. Proceed with fabricating the crown; the model is likely accurate enough.
B. Praise the assistant for their efficiency and remind them of the correct ratio for next time.
C. Have the assistant re-pour the impression immediately using the correct water-to-powder ratio.
D. Instruct the assistant to add more water to the already-mixed gypsum to correct the consistency.
Correct Answer: C. Have the assistant re-pour the impression immediately using the correct water-
to-powder ratio.
Rationale: An inaccurate model compromises the quality of the final restoration and violates the
standard of care. The dentist is ultimately responsible for all procedures performed in their office. The
correct action is to re-pour the model to ensure accuracy. Option A risks a failed restoration. Option B
does not correct the immediate problem, and option D will weaken the gypsum and make it unusable.
5. Which of the following scenarios represents a violation of the Texas Dental Practice Act
regarding patient records?
A. Storing patient charts in a locked cabinet within the practice.
B. Refusing to send a patient's dental records to their new dentist until the patient's outstanding
balance is paid in full.
C. Using a paper charting system alongside a digital radiograph system.
D. Failing to document a patient's verbal consent for a routine procedure in the treatment record.
Correct Answer: B. Refusing to send a patient's dental records to their new dentist until the
patient's outstanding balance is paid in full.
,Rationale: The Texas Dental Practice Act and Board rules require a dentist to provide copies of a
patient's records upon request. A dentist cannot withhold records for non-payment of services.
Option A is a proper security measure. Option C is permissible. While best practice is to document
verbal consent, failing to do so (D) is a less severe issue than refusing to release records.
6. A patient with a history of a severe latex allergy is scheduled for a restorative procedure. What is
the most appropriate initial step for the dental team to take to ensure patient safety?
A. Inquire if the patient has ever had a reaction in a dental setting.
B. Schedule the patient as the first appointment of the day to minimize airborne latex allergens.
C. Remove all latex-containing products from the treatment room and prepare a latex-safe kit.
D. Pre-medicate the patient with an antihistamine before the appointment.
Correct Answer: C. Remove all latex-containing products from the treatment room and prepare a
latex-safe kit.
Rationale: The primary responsibility is to create a latex-safe environment by physically removing all
latex-containing items (gloves, rubber dams, etc.) from the treatment area. While option A is part of
the history, it is not sufficient. Option B (scheduling) is a secondary precaution. Option D is not
standard practice and is less critical than creating an allergen-free environment.
7. According to principles of ethics in dentistry, what is the concept of "autonomy" best
understood as?
A. The dentist's responsibility to use their professional knowledge for the patient's benefit.
B. The patient's right to make informed decisions regarding their own healthcare.
C. The obligation to tell the truth and not deceive the patient.
D. The dentist's duty to avoid causing harm to the patient.
Correct Answer: B. The patient's right to make informed decisions regarding their own healthcare.
Rationale: Autonomy, a core principle of the ADA Code of Ethics, refers to the patient's right to self-
determination and informed consent. Option A describes beneficence. Option C describes veracity,
and Option D describes non-maleficence.
8. A dental office has a policy of "dual booking" patients, meaning two patients are scheduled for
the same time slot to be seen by the same dentist. A dental assistant who is present during
treatment notices a patient becomes visibly anxious and confused because they did not expect
another patient in the adjacent operatory. What is the most likely concern regarding this
scheduling practice?
A. The policy is a violation of the Texas Workers' Compensation Act.
B. The policy may breach patient confidentiality by exposing one patient's identity and presence to
another.
C. The policy will increase the risk of cross-contamination and infection.
D. The policy is a clear violation of the standard of care for all patients.
, Correct Answer: B. The policy may breach patient confidentiality by exposing one patient's identity
and presence to another.
Rationale: While scheduling practices are generally at the discretion of the practice, the primary
ethical and legal concern with "dual booking" is the potential breach of confidentiality. A patient's
presence in the dental office is part of their protected health information. Option C is a risk but can be
mitigated with proper infection control; it is not the primary concern. Option A is not typically
relevant. Option D is an overstatement as dual booking alone does not always violate the standard of
care.
9. A dentist receives a subpoena for a patient's dental records in a personal injury lawsuit. The
patient has not signed a release for the records. What is the dentist's most appropriate legal
response?
A. Immediately provide the complete records to the court as required by law.
B. Comply only if the subpoena is accompanied by a court order.
C. Refuse to comply with the subpoena and inform the court of the patient's lack of consent.
D. Contact the patient's attorney to see if they object to the release of the records.
Correct Answer: D. Contact the patient's attorney to see if they object to the release of the records.
Rationale: A subpoena is a court order to provide records. However, a dentist must first ensure they
are not violating patient confidentiality. The dentist should contact the patient's attorney to
determine if the patient objects to the release. If they do, the attorney will likely file a motion to
quash the subpoena. It would be incorrect to simply provide the records (A) without addressing
privacy, or to outright refuse (C) which could result in contempt of court. While a court order (B)
would compel production, a properly issued subpoena is often sufficient for a court's authority.
10. A dental hygienist is performing a periodontal assessment and notes generalized 5-6mm
pockets with bleeding upon probing. The patient's medical history is significant for controlled Type
2 diabetes. The hygienist recommends a scaling and root planing procedure. The patient is
hesitant, stating they "just want a regular cleaning." What is the hygienist's best communication
strategy?
A. Tell the patient that if they do not agree to the scaling, they will be dismissed from the practice.
B. Explain the difference between a prophylaxis and scaling/root planing, and how the periodontal
condition can affect their diabetes.
C. Agree to the prophylaxis, and document that the patient refused the recommended treatment.
D. Schedule the patient for a prophylaxis and hope that the condition improves with more frequent
cleanings.
Correct Answer: B. Explain the difference between a prophylaxis and scaling/root planing, and
how the periodontal condition can affect their diabetes.
Rationale: This is a classic example of informed refusal. The hygienist must educate the patient on the
nature of their periodontal disease, the importance of treatment, and the relationship between
periodontal health and systemic conditions like diabetes (bidirectional relationship). Option A is
coercive and unethical. Option C is inadequate because it does not address the underlying disease.
Option D is a failure to provide the standard of care.
