When is the best time to select a tooth shade for a restoration?
Show answer and explanation
Correct answer: A. At the beginning of the appointment, before tooth preparation (and before the teeth dehydrate)
Shade should be chosen early, before isolation and preparation, because teeth dehydrate during treatment and appear lighter, leading to mismatched (too-light) selections.Other options: Selecting after dehydration produces an inaccurate, too-light shade; end-of-visit selection is also affected; timing does matter.Key exam takeaway: Choose shade first, before dehydration, ideally under natural light.
