A periapical x-ray is taken to give a general overall view of the sinus area, nasal cavity, and the mandibular nerve.

Periapical radiographs are designed to show one or a few teeth and the bone immediately around their roots, providing detailed information about the tooth, its apex, and surrounding periapical bone. They do not offer a broad survey of the sinus area, nasal cavity, or the path of the mandibular nerve. To view these structures in a meaningful way, you’d use imaging with a wider field of view—such as a panoramic radiograph for the sinus and nasal regions, or CBCT for detailed nerve canal anatomy. Because of the limited field of a periapical image, it cannot reliably give a general overview of those structures.
