Why should the x-ray film be placed parallel to the long axis of the tooth?

To minimize distortion place the film parallel to the teeth. Distortion results from unequal magnification of different parts of the same object. If the film is not parallel to the tooth and/or the central ray is not perpendicular to the object and film plane, image distortion occurs.
