Which is a prerequisite for shade selection for composites?
Shade of the tooth is determined before teeth are subjected to drying because dehydrated tooth becomes lighter in colour as a result of decrease in translucency.
Thus shade is selected on a wet tooth.

Tooth should not be dry as drying increases translucency
Tooth should not be wet as moisture increases translucency
Tooth should not be dry as drying decreases translucency
Tooth should not be wet as it decreases translucency
