Distinguish chair-side shade matching from laboratory shade matching.

Distinguish chair-side shade matching from laboratory shade matching.

• A. Chair-side shade matching is done directly in the mouth under lighting; laboratory shade matching uses controlled conditions, standardized guides, and lab communication.
• B. Chair-side shade matching uses standardized guides; laboratory shade matching is performed in the mouth
• C. Chair-side shade matching uses digital tools only; laboratory shade matching relies on human eye
• D. Chair-side shade matching is unnecessary; laboratory shade matching is only done in the lab

Answer: (A)

Chair-side shade matching is the color assessment done directly in the patient’s mouth under appropriate lighting, so the chosen shade reflects what the patient will see in everyday life. Laboratory shade matching is performed in the lab under controlled conditions using standardized shade guides and clear communication between dentist and lab to ensure the final restoration matches the adjacent teeth. The other statements mix up where shading happens, or overemphasize digital tools, or claim shading in the chair is unnecessary, which doesn’t fit how both steps contribute to a natural-looking result.
