Phim X-quang toàn cảnh (OPG) là gì?

A panoramic radiograph (orthopantomogram or OPG) is a two-dimensional dental X-ray capturing the entire mouth in one image. The machine rotates around the patient's head, showing all teeth, both jaws, TMJ joints, sinuses, and nasal area. Used for treatment planning, wisdom teeth assessment, jaw pathology, and implant evaluation. OPGs are standard in virtually every dental practice.
