If the patient keeps the crown on tooth #10, which shade reference should be used?
Show answer and explanation
Correct answer: D. Value of tooth #10
- A. Matching chroma of a different tooth (#6) won't ensure the new restorations blend with the retained #10 crown.
- B. Chroma alone is the saturation of color; value (lightness) is the most critical dimension for a natural match.
- C. Referencing #6 ignores the existing restoration the patient is keeping.
- D. Correct. To blend new restorations with the crown being retained, match to tooth #10, and VALUE (brightness/lightness) is the most important shade dimension — the eye detects mismatched value first.
