Question

Extraoral radiographs, which are needed to evaluate the height, width, and quality of bone, include which of the following views?

A) Bitewing view
B) Periapical view
C) Panoramic view
D) Occlusal view

Answer 1

Extraoral radiographs, such as panoramic view, lateral cephalometric view, and cone-beam computed tomography (CBCT), are used to evaluate the height, width, and quality of bone.

Step-by-step explanation:

Extraoral radiographs that are used to evaluate the height, width, and quality of bone include the following views:

1. Panoramic view: This view provides a broad view of the entire mouth, including the jawbones and surrounding structures, helping to assess bone structure and density.
2. Lateral cephalometric view: This view focuses on the side of the head, enabling evaluation of bone growth and facial proportions.
3. Cone-beam computed tomography (CBCT): CBCT provides highly detailed 3D images of the teeth and bones, allowing for accurate assessment of bone height, width, and quality.

Answer 2

Extraoral radiographs, which are needed to evaluate the height, width, and quality of bone, include C) Panoramic view.

Step-by-step explanation:

Panoramic views are extraoral radiographs that provide a comprehensive image of the entire mouth, including the upper and lower jaws. Unlike intraoral views like bitewing and periapical, panoramic radiographs capture a broad view of the oral and maxillofacial structures. This makes them particularly useful for assessing the height, width, and quality of the jawbone, aiding in the diagnosis and treatment planning for procedures such as dental implants or oral surgery.

The panoramic view offers a two-dimensional representation of the entire oral region, allowing dental professionals to evaluate the condition of teeth, supporting structures, and adjacent tissues. This view is especially valuable for gaining insights into the overall oral health and bone structure, facilitating a more comprehensive understanding of the patient's dental anatomy. Its non-invasive nature and ability to reveal a broad spectrum of information make the panoramic view an essential tool in dental radiography for assessing bone health and guiding various dental interventions.
