Light Curing

Clinical Relevance The results of this study indicate that preheating composites can improve adaptation of resin composites to tooth structure. This technique significantly reduced microleakage. However, delaying light curing of the preheated composite after placement appears to be counterproductive and diminishes the positive effects from the preheating treatment. Flowable liner was less effective than preheating the composite in reducing microleakage.

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.

Clinical Relevance The effects of polishing techniques on surface roughness, microhardness and microleakage of resin composites are material dependent. In general, since immediate polishing has not had a negative influence on the tested properties of the two composites compared to delayed polishing, this procedure could be preferred, reducing the number of clinic sessions and bringing more comfort and satisfaction to the patient.

Clinical Relevance When using resin composites as core buildup materials, dual-cured resin composites show higher shear bond strength to dentin than self-cured resin composites. Light activation of bonding agents prior to applying a resin composite core can improve the shear bond strength of resin composites to dentin.
