Q: The cutting edge of a hatchet excavator makes an angle with the shaft of: A) 45 degrees B) 90 degrees C) 60-70 degrees D) 100 degrees Answer: D) 100 degrees (Explanation: This is a classic question from Sturdevant. The cutting edge is at an angle of 100 degrees to the shaft (resembling a single-bevel hatchet).)

The keyword "new" is critical. Operative dentistry has evolved dramatically over the last decade. A new PDF should cover:

If your PDF still focuses only on amalgam condensation techniques without discussing composite shrinkage stress or universal adhesives, it is outdated. Always seek a new operative dentistry MCQs PDF from recent editions or exam recalls (e.g., 2023–2025).

1. The term "Remineralization" refers to: A. The process of mineral loss from the tooth structure. B. The process where calcium and phosphate ions are redeposited in the enamel matrix. C. The surgical removal of carious lesions. D. The formation of secondary dentin. Answer: B

2. Which of the following is the most reliable clinical sign of active dental caries on an occlusal surface? A. White spot lesion that is non-cavitated. B. Staining in the pits and fissures. C. Enamel opacity visible after air drying for 5 seconds. D. A "catch" with an explorer tip that requires pressure to remove. Answer: C (Modern operative dentistry discourages using the explorer with pressure to avoid breaking the enamel rod structure; visual assessment after air drying is preferred).

3. In the International Caries Detection and Assessment System (ICDAS), a score of "4" indicates: A. A distinct cavity with visible dentin. B. An extensive cavity with visible dentin. C. Localized enamel breakdown (without dentin exposure). D. Surface with filling or sealant. Answer: C operative+dentistry+mcqs+pdf+new

4. The "Stepwise Excavation" technique is indicated for: A. Acute pulpitis in permanent teeth. B. Deep carious lesions in young permanent teeth with risk of pulp exposure. C. Superficial enamel caries only. D. Non-vital teeth undergoing root canal therapy. Answer: B

5. What is the primary advantage of using a Caries Detector Dye? A. To differentiate between infected dentin and affected dentin. B. To stain the enamel for better visibility. C. To identify micro-leakage in existing restorations. D. To disinfect the cavity preparation. Answer: A (Infected dentin stains deeply, while affected dentin stains lightly or not at all, allowing for conservative excavation).

Q: A patient on long-term anticholinergics has rampant root caries. Which "newer" minimally invasive alternative to conventional GIC is preferred?
A) Silver diamine fluoride (SDF) + potassium iodide
B) Resin-modified GIC with HEMA
C) Highly filled nano-ceramic injectable composite
D) Zirconia-reinforced glass ionomer

Answer: A) SDF + potassium iodide (SDF/KI)
Explanation: SDF arrests caries, KI prevents black staining; this is the current evidence-based protocol for elderly/hyposalivation patients.
