The Effect of Soft-start Polymerization by Second Generation LEDs on the Degree of Conversion of Resin Composite

Abstract

Clinical Relevance Photo-polymerization using second generation LED and halogen light in the soft-start mode of curing was able to produce an adequate degree of conversion in resin composites. The lower degree of conversion produced by low power LED in the soft-start mode could lead to restoration failure, degradation of the organic matrix and recurrent caries.
