PROBLEM TO BE SOLVED: To provide a new system for evaluating intraoral radiography practice wherein intraoral radiography practice can be rapidly and accurately evaluated with a simple configuration and without performing X-ray irradiation. SOLUTION: The system for evaluating intraoral radiography practice includes: a dental cast 1 so configured that tissues 3 around the teeth can be attached and detached while the row of teeth is being fixed; a film simulation plate 6 simulating the shape of an intraoral X-ray film; a holding means 7 for holding the film simulation plate 6; a cone simulation cylinder 9 simulating the shape of an X-ray irradiation indicator cone; a photographing means 10 for photographing an area corresponding to an X-ray irradiation field through the cone simulation cylinder 9; and a display means 13 for displaying the image photographed by the photographing means 10.
