The impact of ground-breaking research on the dental pulp and its response to dental procedures, materials and associated diseases significantly influenced the evolution and scope of Endodontics, creating a science of Endodontology. While there were scattered studies in the early 20th century in this regard, the clarification and codification of these concepts took a major leap forward in the late 1950s due to the academic prowess and in-depth research endeavors of Dr. Kaare Langeland. The story begins during World War I in Norway...

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. Four years later, the developed restorative composite resin ended up as a radiopaque, optically translucent, universal color with an additional three shades that possessed the biologic, esthetic, mechanical and physical characteristics with proven efficacy be used for esthetic zone...
