When taking a dental shade, where should the clinician position themselves relative to the patient?
Show answer and explanation
Correct answer: B. At the patient's eye level
Shade selection should be performed with the observer at the patient's eye level — provides the most accurate angle of reflected light. Brief glances (5 seconds) prevent eye fatigue.
- A. Above eye level changes light reflection angle — teeth appear lighter than actual shade.
- B. CORRECT. Eye-level positioning ensures accurate shade assessment. Source confirms: 'at patient eyes level.'
- C. While lighting (natural daylight) is critical, positioning at eye level is an equally fundamental principle.
- D. Below eye level alters reflection — teeth may appear darker.
