Depth of cure and compressive strength of dental composites cured with blue light emitting diodes (LEDs).

Abstract

OBJECTIVE The primary objective of this pilot study was to test the hypotheses that (i) depth of cure and (ii) compressive strength of dental composites cured with either a light emitting diode (LED) based light curing unit (LCU) or a conventional halogen LCU do not differ significantly. The second objective of this study was to characterise irradiance and… (More)
