The Blue Revolution Over the last five years, we applied all of our technical expertise, in conjunction with scientific and clinical researchers, to develop a patented technology which is based on the principle of fluorescence. The result of this effort is a revolutionary new device—SoproLIFE® SoproLIFE® (Light Induced Fluorescence Evaluator) can diagnose both occlusal or interproximal caries and can differentiate with outstanding accuracy healthy tissue from infected tissue, guiding you to only excavate only the decayed areas. SoproLIFE® is an indispensable aid for the practitioner preferring minimally invasive dentistry.
