Comparison of panoramic and standard radiographic radiation exposures in the diagnosis of mandibular fractures

Radiological examination of the maxillofacial region is required to confirm fractures and to identify lesions that are present in the jaws. The complex anatomy of the area necessitates multiple radiographic views with standard projections. The accuracy of diagnosis is at times suspect. An orthopantomogram, which is supplemented by a posteroanterior projection of the lower jaw where required, allows a more accurate diagnosis. This pilot study was designed to compare the radiation dosage that is delivered after a standard hospital series of films and an orthopantomogram. The results demonstrate the significant reduction in irradiation to patients who undergo orthopantomography.
