Show answer and explanation
Correct answer: A. 2 mm
Conventional composite is placed in ≤2 mm increments.
- A. Correct. Incremental placement of ~2 mm ensures adequate light cure and reduces polymerization shrinkage stress.
- B. 4 mm exceeds reliable depth of cure for conventional composites (bulk-fill is a separate category).
