ADC ADC - Australian Dental Council Clinical Examination and Treatment Planning Questions and Answers 1 — Questions and Answers
Question 1: Which index is used to assess the severity of periodontal disease in the ADC examination context?
- DMFT index
- Basic Periodontal Examination (BPE) (Correct answer)
- OHI-S index
- CPITN score
Correct answer: Basic Periodontal Examination (BPE)
The Basic Periodontal Examination (BPE) uses a WHO probe to screen and record periodontal status using codes 0–4 plus an asterisk.
Question 2: When examining a patient for temporomandibular disorder (TMD), which finding is most significant?
- Clicking sound only on mouth opening
- Deviation of the mandible on opening with restricted range of motion and pain (Correct answer)
- Mild muscle soreness only on palpation
- Slightly reduced interincisal opening with no pain
Correct answer: Deviation of the mandible on opening with restricted range of motion and pain
Deviation with restricted opening and pain together suggest significant TMD and warrant thorough investigation and management.
Question 3: Which test is most appropriate to determine pulp vitality in a tooth with a full-coverage crown?
- Cold test (ethyl chloride)
- Electric pulp test (Correct answer)
- Hot test (gutta-percha)
- Percussion test
Correct answer: Electric pulp test
The electric pulp test is preferred for crowned teeth because it delivers a standardized stimulus through the crown where thermal tests may give unreliable readings.
Question 4: A patient presents with a radiolucency at the apex of a non-vital tooth with no swelling. What is the most likely diagnosis?
- Periapical abscess
- Periapical granuloma or cyst (Correct answer)
- Lateral periodontal cyst
- Dentigerous cyst
Correct answer: Periapical granuloma or cyst
A well-defined periapical radiolucency on a non-vital tooth without acute symptoms most commonly represents a periapical granuloma or radicular cyst.
Question 5: Which ASA classification would be assigned to a patient with well-controlled Type 2 diabetes and no other systemic conditions?
- ASA I
- ASA II (Correct answer)
- ASA III
- ASA IV
Correct answer: ASA II
A patient with well-controlled diabetes and no significant limitations is classified ASA II — mild systemic disease.
Question 6: What is the significance of a sinus tract (fistula) found in the oral mucosa?
- It always indicates acute infection requiring immediate extraction
- It indicates a chronic infection with a draining pathway, often from a necrotic pulp or abscess (Correct answer)
- It is a normal anatomical variant in adults
- It only occurs in association with impacted teeth
Correct answer: It indicates a chronic infection with a draining pathway, often from a necrotic pulp or abscess
A sinus tract is a channel through which chronic infection drains, most commonly originating from a periapical abscess of a non-vital tooth.
