What is it indicated for?

C50 is intended for clinical practice of general dentistry, as an aid in the diagnosis of pit and fissure caries, as an aid to highlight dental plaque and gingival inflammations (restricted to gingival inflammations which lead to bleeding upon probing) and as intra-oral camera to visualize anatomical details invisible to the naked eye or with a mirror (thanks to magnification).

Indications for use as stated in the FDA summary.
