Dental X-Ray–OPG (Orthopantomogram)
Diagnostic Centres have Panoramic radiograph. It 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 mandibleare in the focal trough and the structures that are superficial and deep to the trough are blurred.
An OPG is a panoramic or wide view x-ray of the lower face, which displays all the teeth of the upper and lower jaw on a single film. It demonstrates the number, position and growth of all the teeth including those that have not yet surfaced or erupted. It is different from the small close up x-rays dentists take of individual teeth. An OPG may also reveal problems with the jawbone and the joint which connects the jawbone to the head, called the Temporomandibular joint or TMJ. An OPG may be requested for the planning of orthodontic treatment, for assessment of wisdom teeth or for a general overview of the teeth and the bone which supports the teeth.
Indications
- Impacted wisdom teeth diagnosis and treatment planning - the most common use is to determine the status of wisdom teeth and trauma to the jaws.
- Periodontal bone loss and periapical involvement.
- Finding the source of dental pain
- Assessment for the placement of dental implants
- Orthodontic assessment. pre and post operative
- Diagnosis of developmental anomalies such as cherubism, cleido cranial dysplasia
- Carcinoma in relation to the jaws
- Temporomandibular joint dysfunctions and ankylosis.
- Diagnosis of osteosarcoma, ameloblastoma, renal osteodystrophy affecting jaws and hypophosphatemia.
- Diagnosis, and pre- and post-surgical assessment of oral and maxillofacial trauma, e.g. dentoalveolar fractures and mandibular fractures.
- Salivary stones (Sialolithiasis).
