Is there any new innovation in the area of caries detection?

Yes, Midwest Caries Device (DENTSPLY Professional Midwest) is a handheld device similar to a handpiece that uses fiber-optic technology and a light-emitting diode to reflect light from the surface of the tooth to detect both occlusal and interproximal caries. This instrument is a battery-powered cordless unit and has recently received FDA approval for proximal caries detection.
