Morphological changes in oral mucosa of rabbits induced by light emitting diode [LED] used as dental curing light

ABSTRACT

A dental curing light is apiece of dental tool that is used for the hardening of light cure composites. Many studies have shown these lights induce changes in DNA, mitosis and mitochondria through free radicals production. Light emitting diode [LED] are most commonly used and claim less hazards to the adjacent soft tissues. Current study was therefore designed to observe the morphological changes induced by light emitting diode [LED] as a dental curing light source in oral mucosa of experimental animals
