Which imaging modality best shows the entire jaw on one image?

• A. Panoramic X-ray
• B. Periapical X-ray
• C. Bitewing X-ray
• D. Occlusal X-ray

Answer: (A)

The main idea this item tests is obtaining a single radiograph that covers both the upper and lower jaws. A panoramic X-ray achieves this by using a rotating beam and film (or digital sensor) around the patient’s head to produce one broad image that includes the maxilla and mandible, along with surrounding structures like the sinuses and the temporomandibular joints. This broad view is why it’s best for showing the entire jaw in one image. It’s especially useful for assessing eruption patterns, identifying impacted teeth, planning orthodontic or surgical treatment, and evaluating jaw relationships or pathology on a single shot. Other techniques focus on much smaller areas: periapical images show a tiny region around the tip of a single tooth or a few teeth; bitewings reveal crowns and interproximal spaces mainly to detect caries and bone levels; occlusal views cover one arch at a time and are useful for surface details or assessing large areas, but they do not capture the whole jaw in one image.
