The caries probe with a specially polished surface was developed for the early detection of approximal caries. Clinical studies have shown that more than twice as many carious defects can be detected with the help of transillumination compared to normal probes and mirrors. It has also been proven that fibre optics reveal more dental caries than X-ray examinations, as demonstrated by studies of Prof. Dr. Pieper.
The handle of the device has been improved: an interchangeable attachment set now allows easy switching between White Light and UV Light.
