Orthopantomogram (OPG) X-ray :
What is a dynamogram (OPG) X-ray?
Orthopantomogram (OPG) X-rays are also known as panoramic dental X-rays.
OPG X-rays are used to capture images of the teeth, jawbones, and surrounding areas in just one film. It helps diagnose dental problems and helps plan procedures such as implants and orthodontics.
X-ray OPG is a two dimensional dental X-ray and non-invasive test. It uses a small amount of radiation to take images of the internal tissues of the body. X-ray technology is one of the most widely used and oldest medical imaging techniques.
The jawbone is a horseshoe-shaped curved structure, but produces a flat image on X-rays. This test helps dentists diagnose various medical conditions. For this type of X-ray, the film is placed inside the machine, whereas in conventional X-rays, the film is placed in the patient's mouth.
Why is OPG X-ray done?
This can be done to help with the following types of diagnosis:
tooth position and other bone abnormalities
jaw tumor and oral cancer
Other impacted teeth including wisdom teeth x
sinusitis
advanced periodontal disease
cyst in jaw bone
jaw disorders
erosion of the jawbone due to gum disease or missing teeth
tooth decay, especially under a filling or between two teeth
dental infections, including abscesses under the gum line or under a tooth
Hyperdontia and hypodontia (a genetic condition of having too many or too few teeth)
misaligned jaw
jaw fracture
This test can also help with surgery and treatment planning for dentures, extractions, braces, and implants.
How to prepare for OPG X-ray?
You do not need any extra preparation for this exam. Take off your jewelry, glasses and other accessories, as these can affect the test results. You may need to wear a lead apron to protect yourself from exposure to scattered radiation from the X-ray. You should inform your doctor if you are pregnant or there is any possibility of you becoming pregnant.
