A panoramic radiograph is a special type of x-ray that utilizes a minuscule amount of ionizing radiation to produce a single image of the entire mouth. This includes the mandible, maxilla, teeth, and surrounding tissues and structures. While bitewing radiographs and other intraoral x-rays are often still done, the panoramic x-ray has become integral to the diagnosis and treatment of a wide variety of oral and dental health conditions. Unlike other types of radiographs, it provides dental professionals with information about possible bone abnormalities, the position of the teeth and their roots in relation to each other across the entire mouth, and the maxillary sinuses. Panoramic radiographs are often used by dentists to diagnose gingivitis (periodontal disease), oral cancer, tumors in the jaw, sinusitis, jaw bone cysts, impacted wisdom teeth, and TMJ (temporomandibular joint disorder) and other jaw disorders. There is no special preparation needed for patients to undergo a panoramic x-ray.
