What are the answers to the following questions regarding dental radiography?

Here are the answers to the questions:

8. B) Digital radiography sensors are more sensitive than film, meaning they require lower exposure to produce an image, which reduces the patient's radiation dose.
9. B) A "herringbone" or "tire-track" pattern on a dental film indicates that the film was placed backwards in the oral cavity, causing the X-rays to expose the pattern of the lead foil backing.
10. B) Cement base/Restorations (such as amalgam or gold) are typically the most radiopaque structures on a dental X-ray because they are made of dense materials that absorb a high amount of X-rays, appearing very white.
11. A) Fixer splashes on a film before development will remove the unexposed silver halide crystals, resulting in clear or light spots on the processed radiograph.
12. C) CBCT (Cone Beam Computed Tomography) is the imaging modality commonly used in dentistry for a 3D view, which is crucial for detailed assessment of implant sites and bone volume.
13. A) The Submentovertex (SMV) view is particularly useful for visualizing fractures of the zygomatic arch as it projects the arches laterally, allowing for clear assessment.
