ADC ADC - Australian Dental Council Treatment Planning and Clinical Examination Questions and Answers 2 — Questions and Answers
Question 1: What is the purpose of a study cast (diagnostic model) in treatment planning?
- To fabricate temporary restorations chairside
- To provide a three-dimensional record of the patient's dentition for diagnosis and planning (Correct answer)
- To check the patient's gingival health over time
- To determine the correct shade for ceramic restorations
Correct answer: To provide a three-dimensional record of the patient's dentition for diagnosis and planning
Study casts provide a three-dimensional, permanent record of the patient's occlusion and arch form, enabling detailed diagnosis and treatment planning outside the clinical environment.
Question 2: Which of the following systemic conditions requires antibiotic prophylaxis before invasive dental procedures per current guidelines?
- Well-controlled type 2 diabetes
- Patients with a prosthetic cardiac valve (Correct answer)
- Mild hypertension controlled with medication
- Patients with a previous healed myocardial infarction (>6 months ago)
Correct answer: Patients with a prosthetic cardiac valve
Current guidelines (AHA/ADA) recommend antibiotic prophylaxis for patients with prosthetic cardiac valves before invasive dental procedures due to the risk of infective endocarditis.
Question 3: When assessing a patient's periodontal status, what does a pocket depth of 6 mm with bleeding on probing most likely indicate?
- Healthy sulcus with pseudo-pocketing due to gingival overgrowth
- Active periodontal disease with likely bone loss (Correct answer)
- Normal pocket depth within acceptable limits
- Early gingivitis only
Correct answer: Active periodontal disease with likely bone loss
A probing depth of 6 mm combined with bleeding on probing indicates active periodontitis with probable alveolar bone loss requiring further investigation and treatment.
Question 4: In the ADC examination context, what is the recommended approach for a tooth with a periapical abscess in an otherwise healthy patient?
- Immediate extraction in all cases
- Incision and drainage if fluctuant, with antibiotics only if systemic signs are present, followed by definitive treatment (Correct answer)
- Prescribe antibiotics alone without any surgical intervention
- Leave untreated as periapical abscesses resolve spontaneously
Correct answer: Incision and drainage if fluctuant, with antibiotics only if systemic signs are present, followed by definitive treatment
Management involves local surgical drainage if fluctuant, with systemic antibiotics reserved for cases with spreading infection or systemic signs, followed by definitive root canal therapy or extraction.
Question 5: What is the purpose of a facebow transfer in prosthodontic treatment planning?
- To measure the patient's facial symmetry
- To relate the maxillary cast to the hinge axis of the articulator, replicating the patient's jaw movements (Correct answer)
- To record the vertical dimension of occlusion
- To determine the shade of the patient's teeth
Correct answer: To relate the maxillary cast to the hinge axis of the articulator, replicating the patient's jaw movements
A facebow records the spatial relationship of the maxillary arch to the temporomandibular joint, allowing the dental cast to be mounted on an articulator that mimics the patient's mandibular movements.
Question 6: Which nerve block is most appropriate to anesthetize the mandibular molars for restorative work?
- Long buccal nerve block
- Inferior alveolar nerve block (IANB) (Correct answer)
- Mental nerve block
- Incisive nerve block
Correct answer: Inferior alveolar nerve block (IANB)
The inferior alveolar nerve block (IANB) is the standard injection to anesthetize the inferior alveolar nerve, providing pulpal anesthesia to all mandibular teeth on that side.
