What is the name of a single panoramic x-ray used in dentistry?

The term known for a single panoramic x-ray used in dentistry is "OPG," which stands for Orthopantomogram. This imaging technique captures a comprehensive view of the patient’s entire mouth, including the teeth, jaws, and surrounding structures, in one image.

In contrast to other options, the OPG is specifically designed to provide a broad overview, making it a vital diagnostic tool for dentists. It facilitates assessment of dental and skeletal abnormalities, tooth eruption patterns, and potential dental pathology, helping in treatment planning.

While the term "DPT" refers to the Dental Pantomograph and can sometimes be used interchangeably with OPG, it is more commonly recognized by its abbreviation "OPG." Therefore, while both terms relate to the panoramic x-ray, OPG is more widely used in clinical settings.

The other options do not accurately represent a single panoramic x-ray. A "pano shot" is an informal term that doesn't convey the specificity or technical accuracy necessary for formal communication in dentistry. A "full mouth series" refers to a comprehensive set of intraoral radiographs and is not a single panoramic image. Each of these distinctions highlights why "OPG" is the most appropriate answer.
