FUSION is the most versatile LED light system that allows users to implement multiple functionalities from its advanced modular base kit. In addition to the Standard Light Head that comes with the FUSION Curing Light kit, optional add-on functions can be achieved with: Violet Light Head provides violet light (390 – 430 nm) for (a) oral lesion/cancer screening; (b) curing of lower wavelength initiator adhesives (e.g. TPO) and (c) composite visualization/removal. Oral screening enables early cancer detection using fluorescence generated from tissue and viewed through Fluorescence Viewer that comes with FUSION-to-DOE starter kit. White Light Head offers an exam probe light that provides high power intra-oral illumination and trans-illumination (best used with tacking tip) for detection of dental caries, cracks and location of root canal.
