Q: Which property allows a bulk-fill composite to be placed in 4 mm increments without increasing shrinkage stress?
A) Higher filler load (>80% wt)
B) Addition of thiol-ene monomers
C) Reduced polymerization rate via modified camphorquinone
D) Increased radio-opacity with ytterbium trifluoride
Answer: C) Reduced polymerization rate via modified camphorquinone (or alternative initiators)
Explanation: Slower polymerization allows stress relaxation; true "low-stress" bulk-fills use novel thiol-ene or alternative initiator systems.

Q1: Are operative dentistry MCQs enough to pass the INBDE? A: Not alone. You need patient boxes and case-based questions. However, operative MCQs form ~15-20% of the exam. Use the PDF as a foundation, then move to case sets.
Q2: Can I find operative dentistry MCQs PDF in Hindi or other languages? A: Most standard PDFs are in English. However, some Indian publishers (like CBS Publishers & Distributors) release bilingual editions.
Q3: How often should I update my MCQ PDF? A: Every 2 years. Adhesive systems and materials evolve rapidly. A 2019 PDF will not mention "universal adhesives" or "silanization of lithium disilicate."
