Radiography is an imaging technique that uses electromagnetic radiation other than visible light, especially X-rays, to view the internal structure of a non-uniformly composed and opaque object (i.e. a non-transparent object of varying density and composition) such as the human body.

X-Ray during pregnancy
Much like the risk estimates in adults, fetal risk estimates are not proven with any certainty, but are taken very seriously. We know that children are more sensitive than adults, so we assume the fetus is at even higher risk. If there is any chance you may be pregnant, you must inform your doctor as well as the staff that is performing procedures.
What is OPG
A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw. It shows a two-dimensionalview of a half-circle from ear to ear. Panoramic radiography is a form of 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 deep to the trough are blurred.

How to Prepare for Dental X-rays?
You will be asked to wear a lead apron as a safety precaution to protect the rest of your body from any radiation exposure that may scatter from the dental x-rays. You may also be asked to remove your jewelry from the region being imaged, eye glasses and any metal objects that might interfere with the x-ray images.
Women should always inform their dentist or oral surgeon if there is any possibility that they are pregnant. If an x-ray is necessary, precautions will be taken to minimize radiation exposure to the baby.
After Dental X-Rays
When the images are ready—instantly in the case of digital X-rays—your dentist will review them and check for abnormalities. He or she will discuss the results with you.
If your dentist finds problems, such as cavities or tooth decay, he or she will discuss your treatment options. If your dentist finds no problems, keep up the good work.
