Abstract
A dental dispensing tray has a plurality of wells formed in a substrate, along with a cover that is slidably attached to the substrate. The cover transmits at least a portion of the visible light spectrum but does not transmit a substantial portion of actinic radiation that might otherwise prematurely cure photocurable material in the wells.
