A recent article about curing lights appreared in Inside Dentistry1 and since that is a topic that I cover for our participants in two workshops, Anterior Restorative Dentistry and Excellence in Composite Restorations, it caught my attention and my interest.
There was one bit of information that was new to me so I'd like to pass it on. LED lights that emit multiple frequencies, the poly-wave LED lights, should be moved over the materials as you are light curing because the frequencies do not mix well together. Moving the light ensures that all areas of the composite material interact with the appropriate frequency of light and initiate polymerization. Who knew? Apparently the ADA, since this is where the authors got the information.2
Don't forget to Move it, Move it!
