Paper Abstract

The objective of this study was to characterize the photo activation reaction of experimental graphene dental nanocomposites and to compare this reaction between commercial nanocomposite by dynamic laser speckle patterns. One commercial nanocomposite and two experimental graphene nanocomposites were used. LED curing unit was used to produce the photo activation reaction and the speckle patterns were generated by the incident light from the laser diode. These patterns were captured with the CMOS camera; later the speckle correlation was calculated. The photo activation process originates different speckle patterns between the commercial and the experimental graphene nanocomposites; having this less speckle activity.
