The Waters projection is also known as what?

• A. Occipitomental II projection
• B. Lateral cephalometric projection
• C. Submentovertex projection
• D. Panoramic projection

Answer: (A)

The Waters projection is an occipitomental projection. This view is used to visualize the maxillary sinuses and is produced by positioning the head with the chin elevated toward the film, which places the petrous ridges below the maxillary sinuses on the image. In some texts, this same view is labeled Occipitomental II projection. The other options describe different skull or dental radiographs (lateral cephalometric, submentovertex, panoramic) and not this particular sinus-focused view.
