Effectiveness of composite resin polymerization using light-emitting diodes (LEDs) or halogen-based light-curing units
Composite resins Spectrophotometry
2009/10/20
The clinical performance of composite resins is greatly influenced by the quality of the light-curing unit used. The aim of this study was to compare the efficiency of a commercial light-emitting diod...
Safety assessment of near infrared light emitting diodes for diffuse optical measurements
Safety assessment diffuse optical measurements
2010/3/1
In this study, we demonstrate that the major risk source of the LED in direct contact with skin is the conducted heat of the LED semiconductor junction, which may cause serious skin burns. Adjusting o...
