A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw.It shows a two-dimensional view of a half-circle from ear to ear. Panoramic radiography is a form of focal plane tomography; thus, images of multiple planes are taken to make up the composite panoramic image, where the maxilla and mandible are in the focal trough and the structures that are superficial and ...
Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities.. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor.
In some cases, teeth might show slightly amber-coloured, but in most of the cases permanent teeth are unaffected and appear normal regardless of colour, shape and size. Dental X-rays are the key to diagnosing dentine dysplasia, especially on permanent teeth. Abnormalities of the pulp chamber is the main characteristic to make a definitive ...
An orthopantomogram (OPG) is a panoramic dental X-ray of the upper and lower jaw. It shows a two-dimensional image from ear to ear. It shows a two-dimensional image from ear to ear. Particularly, OPG facilitates an accurate postoperative follow-up and monitoring of bone growth under a mono- or double-distractor treatment.
Dental panoramic radiograph showing Stafne defect in the right mandible, below the inferior alveolar nerve canal (arrowed, appears on lower left of image). This x-ray was taken for an unrelated assessment of wisdom teeth, and the Stafne defect was a chance finding. Axial computed tomograph of the same person.
Panoramic radiographs [3] can also be used to confirm the presence of an OAC. If simple radiographs are deemed not to give enough information, cone beam computed tomography (CBCT) [3] (special x-ray equipment that can scan in 3 dimensions) may be used. Imaging can help locate the communication, determine the size of it and can give an ...
X-ray showing supernumerary teeth in the premaxillary area. Supernumerary teeth may be detected by taking two different dental X-rays at different angles. Examples of this may be an intra-oral X-ray (one that is taken inside the mouth) and a panoramic radiograph.
This section from a panoramic X-ray film depicts the teeth of the lower left quadrant, exhibiting generalized severe bone loss of 30–80%. The red line depicts the existing bone level, whereas the yellow line depicts where the gingiva was located originally (1–2 mm above the bone), prior to the person developing periodontal disease.
