An Update on Demineralization/Remineralization
Fiber-Optic Transillumination

When the product originally launched, optical transillumination was taken to a new level with DIFOTI, an instrument designed for the early detection of demineralized enamel. Schneiderman et al.³² in vitro results showing more sensitivity than bitewing radiography for early caries detection using this technology. Keem and Elbaum,³³ also using in vitro data, concluded DIFOTI was superior to radiography, based on their position that, using DIFOTI, there is "no ionizing radiation, no film, real-time diagnosis, and higher sensitivity in detection of early lesions not apparent to X-ray."
