Question 1

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:

Accepted Answer

Incisional biopsy for histopathologic evaluation

Answer

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.

Question 2

Which principle of tooth preparation MOST directly prevents a full-coverage crown from rotating on the prepared tooth?

Accepted Answer

Resistance form

Answer

Resistance form prevents displacement of the restoration from oblique or lateral forces, including rotation, through features like flat occlusal planes and auxiliary grooves.

Question 3

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:

Accepted Answer

Duration of bisphosphonate use and route of administration

Answer

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).

Question 4

When using a rubber dam during endodontic treatment, the MAIN clinical benefit is:

Accepted Answer

Preventing aspiration/ingestion of instruments and providing a sterile field

Answer

Rubber dam isolation prevents accidental swallowing or aspiration of files and irrigants while maintaining a clean, bacteria-reduced operating field.

Question 5

Which caries risk assessment model, widely used in the US, categorizes patients based on biological, protective, and clinical findings?

Accepted Answer

CAMBRA (Caries Management by Risk Assessment)

Answer

CAMBRA is the evidence-based caries risk assessment system that integrates disease indicators, risk factors, and protective factors to guide personalized prevention and treatment.
