Which statement is NOT true about dental radiography safety?

• A. The operator should stand behind a wall or barrier when taking x-rays on a patient.
• B. Lead aprons are required when taking conventional x-rays.
• C. BW stands for bitewings.
• D. A periapical x-ray is taken to give a general overall view of the sinus area, nasal cavity, and the mandibular nerve.

Answer: (D)

In dental radiography safety, the goal is to minimize exposure by using barriers, shielding, and appropriate imaging choices. The operator should stand behind a wall or barrier to reduce scatter exposure, and protective gear like lead aprons is a standard precaution for conventional x-rays. Bitewings refer to a specific small-field view used to detect interproximal caries and assess bone levels between teeth. A periapical radiograph, however, is intended to image one or a few teeth and the surrounding bone up to the tooth apex, not to provide a general survey of the sinus area, nasal cavity, or the mandibular nerve. For evaluating broader anatomy like the maxillary sinuses or the inferior alveolar canal, panoramic radiographs or other specialized views are used.
