The present study was designed to evaluate the ability of photoroentgenographic panoramic radiography in detecting experimental bony defects in the jaws by comparison with conventional panoramic radiography. Bony defects in the lingual site of the anterior and molar regions of the jaws and the lingual site of the premolar region of the lower jaw were equally detected by both panoramic radiography. However, bony defects in the labial site of the anterior and premolar regions of the jaws and the lingual site of the premolar region of the upper jaw were predominantlly detected by conventional panoramic radiography.There was no differences on the detection of bony defects, which have diameters from 2mm to 4mm, between photo-roentgenographic and coventional panoramic radiography. However, there was no differences, on the detection of the bony defect with a diamere of 5mm, between photo-roent-ogenographic and conventional panoramic radiography.

本研究旨在通过与传统全景X线摄影的比较，评价光断层全景X线摄影在检测实验性颌骨骨缺损中的能力。两种全景X线摄影均检测到颌骨前磨牙区舌侧部位和下颌前磨牙区舌侧部位的骨缺损。而常规曲面断层片主要检出上颌前牙区唇侧和前磨牙区舌侧的骨缺损，对直径2 ~ 4 mm的骨缺损的检出率与普通曲面断层片无差异。而对于直径为5 mm的骨缺损，光片与普通曲面断层片的检出率无差异。
