Using mouth mirror it is difficult to check up a status of dentition precisely. In this situation intraoral camera is very helpful, both in diagnostics and, for example, in complicated root canal treatment. Also we can use it instead of X-ray apparatus. It is one of the best way of carietic defects detection, particularly defects on tangent surfaces (between teeth).

A dentist places a thin tube with camera at the apex in patient’s mouth. The tube is connected with computer, so we obtain enlargement of teeth and gums on the monitor screen.
A patient can observe the dentist’s work on the screen. At the end of a visit the patient receives a printout of teeth in order to compare their condition during next visits.
