Utilize your dental X-ray set better.
The dental X-ray set should not be used in a stereotyped way, but should be regarded as an instrument with a wealth of potential. For its optimal utilization the operator should be familiar with the principles of projection geometry and of image formation. The diagnostic problem should be analysed so that the determination of projections and angulations of the X-ray beam will result in the maximum information. To ascertain true morphology and interpret the radiographic images three-dimensionally multiple views are required. Distortion is a disturbing factor in radiographic image formation and methods minimizing distortion are to be preferred. The benefits of occlusal radiography are emphasized. In order to limit the detrimental effects of ionizing radiation X-ray examinations should not be used unless the outcome represents a net benefit to the patient. However, it is wrong policy to restrict the number of radiographs in dental practice if substantial indications for radiography exist.
