It is often encountered in dental practice and occasionally in the emergency department; providing a convenient, inexpensive and rapid way to evaluate the gross anatomy of the jaws and ...

An orthopantomogram (OPG) is a common radiograph used to identify the hard tissues of the oral cavity and surrounding skeletal structures. It is an extra-oral radiograph that approximates the focal trough of the mandible.

2021年7月1日 · Panoramic films (OPTs/DPTs/OPGs) are a form of extra-oral radiograph that we take in dentistry. They provide an overview of the patient’s dentition as well as surrounding …

This article provides a guide to identifying key anatomical features on the radiograph and outlines its use in identifying pathology such as dental disease, cysts and traumatic injuries to the hard tissues of the face. An OPG is often ordered by dentists as a screening tool as it gives a complete view of the teeth and jaws.

2014年12月1日 · This presentation demonstrates the normal anatomy seen on the OPG, as well as artefacts produced by the tomographic technique, and incorrect patient positioning.

The normal anatomy of the OPG is complicated as a result of the tomographic technique. The image is produced by both the film and the x-ray source rotating around the stationary patient. This tomographic technique results in a panoramic image of the dental arches and surrounding bone, soft tissue structures and air cavities.

2022年1月1日 · The main anatomical characteristics of an OPG are described in this article, along with some typical pathologies that might be present.
