Light Curing or Light Killing ?!


"Let there be light: and there was light." The light curing unit is a must-have "magic" tool in modern dentistry that can initiate radicals formation in resin-based dental materials. In fact, different resin products contain various photo-initiators and thus manufacturers are making their own light curing units specific for their products. We had some low power halogen light powered devices decades ago but now we have LEDs that are advocated for their high power and narrow wavelength(s), from blue to purple and from monowave to polywave. These units also possess different hazards to the materials and dental practitioners if not used properly. How to choose the light for a better clinical practice? In this workshop, we will talk about some basics and updates about light curing technologies, and there are some demo and testing units for you to try, whereas you are also welcome to bring your current light curing unit for trial.
