Laser versus LED polymerization: Comparison of in vitro preventive sealing procedures.

Introduction:: The technique of sealing is a widely accepted procedure for prevention of caries. The aim of our in vitro study was to compare the effect of two different curing units (traditional LED source and innovative laser diode lamp) on the integrity of fissure sealant material and its interface with tooth enamel.

Materials And Methods:: Sixty healthy third molars were randomly assigned to two groups.
