Dental Review and Assessment 2 — Questions and Answers
Question 1: During a comprehensive oral evaluation, which classification system is most commonly used to record periodontal disease severity?
- AAP staging and grading (Correct answer)
- ASA physical status
- Mallampati score
- Angle classification
Correct answer: AAP staging and grading
The AAP (American Academy of Periodontology) staging and grading system classifies periodontal disease severity and progression.
Question 2: A probing depth of 5 mm with bleeding on probing and 2 mm of recession indicates what clinical attachment loss?
- 3 mm
- 5 mm
- 7 mm (Correct answer)
- 2 mm
Correct answer: 7 mm
Clinical attachment loss equals probing depth plus recession, so 5 mm + 2 mm = 7 mm.
Question 3: Which radiograph is the standard of choice for detecting interproximal caries?
- Bitewing (Correct answer)
- Panoramic
- Lateral cephalometric
- Occlusal
Correct answer: Bitewing
Bitewing radiographs best reveal interproximal (between-teeth) caries and crestal bone levels.
Question 4: When assessing a patient's blood pressure of 165/95 mmHg, this reading is classified as which stage of hypertension?
- Normal
- Elevated
- Stage 1
- Stage 2 (Correct answer)
Correct answer: Stage 2
A systolic of 140+ or diastolic of 90+ mmHg is classified as Stage 2 hypertension under current guidelines.
Question 5: Which finding during an oral cancer screening is MOST concerning and warrants biopsy?
- Bilateral linea alba
- A non-healing ulcer present over 2 weeks (Correct answer)
- Fordyce granules
- Geographic tongue
Correct answer: A non-healing ulcer present over 2 weeks
A non-healing ulcer lasting more than two weeks is a classic warning sign of oral malignancy.
Question 6: On a periodontal chart, a Class II furcation involvement indicates the probe can be inserted:
- Into a slight notch only
- Horizontally but not through the furcation (Correct answer)
- Completely through the furcation
- No detectable involvement
Correct answer: Horizontally but not through the furcation
Class II furcation allows horizontal probe entry but the probe cannot pass completely through.
Question 7: Which mobility classification describes a tooth that can be moved more than 1 mm horizontally but not vertically?
- Class 0
- Class 1
- Class 2 (Correct answer)
- Class 3
Correct answer: Class 2
Class 2 mobility is horizontal movement greater than 1 mm without depressibility into the socket.
