New light curing options for composite resin restorations.

The concerned practitioner needs to understand the chemistry of the materials, the dynamics of polymerization, the stress factors created, and the specific light energy requirements needed to attain maximum results. If a practitioner chooses to use one of the nontraditional curing systems, he or she needs to consult with the manufacturer to determine the spectral output of the system, and contact the manufacturer of the composite to ensure that the material used will cure properly with the chosen light source. The manufacturers have customer service representatives who are usually very knowledgeable about their products. Current claims about new technological developments based on laboratory experiments and anecdotal information are promising. However, multicenter prospective clinical studies are still needed to validate safety and efficacy. Then clinicians can make informed decisions that will enable them to provide the highest quality dentistry for their patients. We will revisit this topic as more information becomes available.
