The effects of exposure time on the surface microhardness of three dual-cured dental resin cements
(2011-09-01)
This study evaluated the exposure time of light-curing of the polymers used for cementation on microhardness test in different storage times. The polymers (specifically called resin cements) were RelyX ARC, RelyX U100, and ...

Effects of light exposure time on composite resin hardness after root reinforcement using translucent fibre post
(ELSEVIER SCI LTD, 2008)
Objectives: The purpose of this in vitro study was to evaluate the Vickers hardness (VHN) of a Light Core (Bisco) composite resin after root reinforcement, according to the light exposure time, region of intracanal ...
Bond Strength of Fiber Posts to Weakened Roots After Resin Restoration With Different Light-Curing Times
(ELSEVIER SCIENCE INC, 2009)
Introduction: This study evaluated the bond strength of translucent fiber posts to experimentally weakened radicular dentin restored with composite resin and polymerized with different light-exposure time. Methods: Roots ...
Non-visual photopigments effects of constant light-emitting diode light exposure on the inner retina of Wistar rats
(Frontiers Media S.A., 2017-08)
The retina is part of the central nervous system specially adapted to capture light photons and transmit this information to the brain through photosensitive retinal cells involved in visual and non-visual activities. ...
Entrainment of circadian rhythms to irregular light/dark cycles: A subterranean perspective
(Nature Publishing Group, 2016-10)
Synchronization of biological rhythms to the 24-hour day/night has long been studied with model organisms, under artificial light/dark cycles in the laboratory. The commonly used rectangular light/dark cycles, comprising ...
