Do you remember the days of rotary telephones? Technology is constantly evolving, and light curing should too! Curing technology has remained largely unchanged over the last decade. In this presentation you will be introduced to an evolution in light curing. One that overcomes the limitations of curing lights as we know them. Review the critical criteria of evaluating curing lights and how you can achieve better depth of cure, higher conversion (hardness), with less shrinkage (associated with sensitivity and failure.)
