Effect of C-factor and LED Curing Mode on Microleakage of Class V Resin Composite Restorations

Abstract

Fast curing mode of LED curing light resulted in more microleakage at the gingival floor of class V cavities with high C-factor. There was no difference in dye penetration between enamel and dentin margins of the cavities except when the fast curing mode was used with high C-factor cavities. Both quantitative and qualitative measurements of microleakage gave the same results at both enamel and dentin margins.
