2D dental panoramic X-ray

The dental panoramic X-ray, also called an orthopantomogram (OPG), is a specialized radiograph that provides, in a single image, a complete, unfolded view of both dental arches, the upper and lower jaws, the temporomandibular joints and the adjacent bone structures. This technique uses an X-ray beam that rotates around the patient's head during acquisition, producing a 2D panoramic image. This examination is fundamental in dentistry and maxillofacial surgery. It makes it possible to visualize the entire dentition (present, impacted and supernumerary teeth), the condition of the roots and alveolar bone, extensive carious lesions, periapical infections (cysts, granulomas, abscesses), periodontal disease with bone loss, tumors and cysts of the jaws, as well as mandibular fractures. The dental panoramic X-ray is a rapid, low-radiation and non-invasive first-line examination. It provides a valuable overall view that guides the practitioner toward additional examinations if necessary (cone beam CT, CT scan). It is systematically requested before orthodontic treatment, wisdom tooth extraction, dental implant placement or any maxillofacial surgery. At Clinique Pasteur in Tunis, the 2D digital dental panoramic unit provides high-resolution images allowing an accurate diagnosis. The examination is quick, comfortable and delivers a very low radiation dose, equivalent to about one day of natural exposure to background radiation.
