Soft Start

Clinical Relevance The preheating of resin composite prior to curing yielded a better degree of conversion but had a negative impact on the induced post-gel shrinkage strain; soft-start mode is recommended, as it reduces the post-gel shrinkage strain without affecting the degree of conversion.

Restoration Failure

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.

Lower Irradiance

Clinical Relevance Curing methods using lower irradiance levels were shown to be effective in reducing the rate of stress generation without compromising the conversion of the restorative composite. Higher C-factor was shown to enhance the stress rate and amount of stress generated.
