Resumen de Automotive Technology Revolutionized Restorative Dentistry Discovery of Alpha- diketone/Amine Catalyst:: Part II - Reflections on Photopolymerization from Conception to Development of Composite Resin and Activator Light

Mohamed Ali Bassiouny, J.A. Yearn

• A full account of the preceded early research tribulation that led to the development of the first visible light activated composite resin and the first visible light activator source is documented. The events took place over four years since early 1974 when a raw industrial composite resin that was radiolucent, stiff paste, universal optically opaque white color, polymerized by exposure to a prototype visible light for 120 seconds was given to developed.
