Analysis of the microtensile bond strength to enamel of two adhesive systems polymerized by halogen light or LED
Adhesives Dental bonding Polymerization Light-emitting diode (LED)
2009/10/20
With the development of composite resin polymerization techniques, LEDs were introduced to the market place. Based on the studied literature, the aim of this study was to evaluate, through microtensil...
Water sorption of resin-modified glass-ionomer cements photoactivated with LED
Glass ionomer cements Water Light
2009/10/19
The Light Emitting Diodes (LED) technology has been used to photoactivate composite resins and there is a great number of published studies in this area. However, there are no studies regarding resin-...
Reducing, by Pulse Width Modulation,the Curing Temperature of a Prototype High-power LED Light Curing Unit
Light emitting diode (LED) Light curing units (LCUs) Pulse width modulation (PWM)
2009/9/14
Third-generation LEDs have high irradiance and efficiency, but the associated temperature rise is potentially hazardous to the pulp of teeth. We evaluated, during composite polymerization, the irradia...
Stability and Reproducibility of Radiometric Properties of Light Curing Units (LCUs). Part II: LED LCUs
LED light curing units (LED LCUs) Radiometric properties Spectral emission
2009/9/11
The present work is the second part of a study on the stability and reproducibility of the energy and spectral emission of some light curing units (LCUs). In this part, Part II, LED LCUs were investig...
Microleakage beneath Ceramic and Metal Brackets Photopolymerized with LED or Conventional Light Curing Units
Ceramic bracket Metal bracket Microleakage LED curing Photopolymerization
2008/11/24
Objective: To test the null hypotheses that (1) the type of light curing unit used (quartz-tungsten-halogen [QTH] or light-emitting diode [LED]) would not affect the amount of microleakage observed ...
