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 ...
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. ...
In-Office dental bleaching efficacy assessment in function of the light exposure regime by digital colometric reflectance spectroscopy
(2011)
In-office dental bleaching has been subject of several studies. Generally those studies quantify through visual analysis, the shade reduction of the teeth submitted to different bleaching protocols (light sources, bleaching ...
Exposure to ambient levels of particles emitted by traffic worsens emphysema in mice
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
Objectives: We investigated effects of chronic exposure (2 months) to ambient levels of particulate matter (PM) on development of protease-induced emphysema and pulmonary remodeling in mice. Methods: Balb/c mice received ...
Effect of curing time on the bond strength of a bracket-bonding system cured with a light-emitting diode or plasma arc light
(European Orthodontic SocietyPorto Alegre, 2011)
The purpose of this study was to assess the influence of two light units, a light-emitting diode (LED) and a plasma arc light (PAC), on the shear bond strength (SBS) of brackets bonded to enamel. Ninety bovine teeth were ...

Antimicrobial photodynamic action on dentin using a light-emitting diode light source
(Mary Ann Liebert, Inc., 2008-08-01)
Objective: The aim of this study was the evaluation of two different photosensitizers activated by red light emitted by light-emitting diodes (LEDs) in the decontamination of carious bovine dentin.Materials and Methods: ...
Chronic exposure to fine particulate matter emitted by traffic affects reproductive and fetal outcomes in mice
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
Air pollution is an important environmental health risk factor that can result in many different gestational and reproductive negative outcomes. In this study, we have investigated the effects of two different times of ...
Shear bond strength of metallic brackets photo-activated with light-emitting diode (LED) at different exposure times
