Which composite resin shade will take the longest time to light cure?
Show answer and explanation
Correct answer: B. D3
- A. ❌ C3 is less chromatic/lighter than D3 — will cure faster.
- B. ✅ Correct. Darker and more chromatic shades absorb more light and scatter it internally, reducing penetration depth and requiring longer cure times. D3 has higher chroma and darker value than C3 or D2, making it the slowest to cure.
- C. ❌ D2 has a lower chroma number than D3 — cures faster.
- D. ❌ A1 is among the lightest, most translucent shades — cures fastest.
