Purpose: To determine the extent of radiant exposure (RE) attenuation of three LED light-polymerization units (LPUs), and their beam-profile, at the bottom of the Class-2 slot, using MARC-PS.
Methods: 10 seconds RE was delivered to MARC-PS' anterior sensor by Bluephase-Style, Demi-Plus, and Deep-Cure-S. Two ivorine lower first-molars received Class-2 proximal box preparations: (3×2×4 mm and 4×4×4 mm) and were sectioned horizontally above the cementoenamel junction.
