A dentist notes a 4 mm × 4 mm white patch on the lateral border of the tongue that cannot be wiped off. It has been present for 3 months. The most appropriate initial management is:
Answer: Incisional biopsy for histopathologic evaluation
A persistent white lesion that cannot be wiped off and does not resolve within 2–3 weeks requires biopsy to rule out dysplasia or malignancy.
Which principle of tooth preparation MOST directly prevents a full-coverage crown from rotating on the prepared tooth?
Answer: Resistance form
Resistance form prevents displacement of the restoration from oblique or lateral forces, including rotation, through features like flat occlusal planes and auxiliary grooves.
A patient using a bisphosphonate for osteoporosis requires extraction of a mandibular molar. The MOST important factor in assessing risk for medication-related osteonecrosis of the jaw (MRONJ) is:
Answer: Duration of bisphosphonate use and route of administration
Intravenous bisphosphonates carry far greater MRONJ risk than oral agents, and risk increases significantly with cumulative duration of use (>4 years oral; any IV use).
When using a rubber dam during endodontic treatment, the MAIN clinical benefit is:
Answer: Preventing aspiration/ingestion of instruments and providing a sterile field
Rubber dam isolation prevents accidental swallowing or aspiration of files and irrigants while maintaining a clean, bacteria-reduced operating field.
Which caries risk assessment model, widely used in the US, categorizes patients based on biological, protective, and clinical findings?
Answer: CAMBRA (Caries Management by Risk Assessment)
CAMBRA is the evidence-based caries risk assessment system that integrates disease indicators, risk factors, and protective factors to guide personalized prevention and treatment.
A patient refuses local anesthesia and demands extraction of a tooth without it. What is the MOST ethical course of action for the dentist?
Answer: Explain the risks, document refusal, and proceed only if the patient provides informed refusal
After thorough explanation of risks including pain and physiologic stress, the dentist may proceed if the patient signs an informed refusal, as patient autonomy must be respected.
In pediatric dentistry, which space maintainer is MOST appropriate following premature loss of a mandibular second primary molar in a 7-year-old with the first permanent molar erupted?
Answer: Band-and-loop space maintainer
A band-and-loop space maintainer is indicated when the first permanent molar has erupted and an adjacent primary molar is lost, preventing mesial drift of the permanent molar.
