Dental Review and Assessment 3 — Questions and Answers
Question 1: Which intraoral landmark is assessed to evaluate the depth of the vestibule during a soft-tissue exam?
- Mucobuccal fold (Correct answer)
- Retromolar pad
- Incisive papilla
- Rugae
Correct answer: Mucobuccal fold
The mucobuccal fold marks the junction where attached gingiva meets the loose mucosa of the vestibule.
Question 2: A DMFT index of 8 in an adult patient quantifies what?
- Plaque coverage percentage
- Decayed, missing, and filled teeth (Correct answer)
- Gingival bleeding sites
- Bone loss in millimeters
Correct answer: Decayed, missing, and filled teeth
DMFT stands for Decayed, Missing, and Filled Teeth, summarizing lifetime caries experience.
Question 3: Which medication noted in a health history most increases concern for gingival enlargement?
- Amoxicillin
- Phenytoin (Correct answer)
- Ibuprofen
- Levothyroxine
Correct answer: Phenytoin
Phenytoin, an anticonvulsant, is a classic cause of drug-induced gingival overgrowth.
Question 4: When evaluating occlusion, a Class III molar relationship is characterized by the mandibular first molar being positioned:
- Distal to normal
- In normal alignment
- Mesial to normal (Correct answer)
- Cross-bite only
Correct answer: Mesial to normal
In Angle Class III, the mandibular first molar is mesial (forward) relative to the maxillary molar, giving a prognathic profile.
Question 5: Which gingival index assessment uses a probe to elicit bleeding to score inflammation?
- Plaque Index
- Gingival Bleeding Index (Correct answer)
- Calculus Index
- Stain Index
Correct answer: Gingival Bleeding Index
The Gingival Bleeding Index scores inflammation based on bleeding provoked by gentle probing.
Question 6: A patient reports an allergy to penicillin. Which antibiotic is the appropriate alternative for dental prophylaxis?
- Amoxicillin
- Ampicillin
- Clindamycin (Correct answer)
- Cephalexin
Correct answer: Clindamycin
Clindamycin is a standard prophylaxis alternative for patients allergic to penicillins.
Question 7: Which assessment tool is used to evaluate a patient's risk for caries based on multiple factors?
- CAMBRA (Correct answer)
- ASA classification
- Glasgow scale
- Apgar score
Correct answer: CAMBRA
CAMBRA (Caries Management By Risk Assessment) evaluates a patient's caries risk using protective and pathological factors.
