Common questions
Is a panoramic dental X-ray harmful?
The dose is very small, less than a chest screening X-ray. The benefit for your treatment is much greater.
How is an OPG different from a dental CT scan?
An OPG is a flat picture of all your teeth. A CT gives a 3D view. It is done, for example, before implants.
