1. A method of three-dimensionally visualizing the curvature of the root canal of a tooth, the method comprising:
(a) displaying a CT image of one or more teeth on the basis of CT image data of the one or more teeth;
(b) three-dimensionally rendering at least a portion of the root canal of a target tooth when a dental practitioner selects the target tooth on the CT image; and
(c) representing a curvature of at least a portion of the root canal that is three-dimensionally rendered in a visually identifiable manner,
wherein in response to an operation in which the dental practitioner designates a position on at least a portion of the root canal on a three-dimensionally rendered image, the representing (step (c)) comprises visually representing a curvature at the designated position using a visual factor, and
wherein the representing (step (c)) comprises representing a curvature at a position designated by the dental practitioner as a circle abutting the root canal and providing the dental practitioner with the radius of the circle in response to an operation in which the dental practitioner designates the position on the three-dimensionally rendered image of the root canal.
