EVALUATION OF MODIFIED EXTRAORAL TECHNIQUE IN ZYGOMATIC ARCH EXAMINATION

並列摘要


The zygomatic arch is the one of the commonest bone to get fractured in the face due to trauma, and the imaging of zygomatic arch is important in diagnosis and treatment of fractures. Occlusal and extraoral films require different exposure parameters, so the image characteristics of both the radiographs also varies. Thus we aimed to evaluate and compare the reliability of occlusal films in relation to extraoral films by modified extraoral technique in zygomatic arch examination. A total 50 subject will be randomly selected and divided equally into group A and B. Zygomatic arch in group A subjects was imaged on occlusal films while for group B subjects on extraoral films by modified extraoral technique. The image quality in two groups will be assessed by two observers and statistically analyzed using SPSS version 18.0 software. Statistically, the inter observer reliability of both the radiographs were found satisfactory and image quality was also acceptable. So this technique can be also used in dental office setup in patients having cervical injuries or suspected cervical injuries, thus overcoming the drawback of the jug handle view, and is easy to master.
