An Orthopantomogram (OPG) is a specialized dental X-ray that captures a panoramic view of the entire mouth, including the teeth, jaws, jaw joints, and surrounding bone structures. It is commonly used to detect impacted teeth, dental infections, jaw fractures, cysts, tumors, and bone loss due to gum disease. Dentists often recommend an OPG before dental surgeries, implants, or orthodontic treatments.
