OPG (Orthopantomogram) is a specialized dental X-ray that captures a panoramic view of the entire jaw, teeth, and surrounding structures in a single image. It is widely used in dentistry to assess tooth development, detect fractures, infections, and gum diseases, and plan orthodontic treatments. OPG is a quick, non-invasive procedure that helps dentists evaluate both the upper and lower jaw simultaneously. The scan uses low-dose radiation, making it a safe diagnostic tool for routine dental checkups. It is especially useful in identifying impacted wisdom teeth and jawbone abnormalities. OPG plays a crucial role in dental and maxillofacial diagnostics for effective treatment planning.
