What does the Water's projection primarily show?

The Water's projection, also known as the occipitomental view, is primarily utilized in radiography to visualize the maxillary sinuses. This technique provides a clear view of the sinus anatomy by allowing the X-ray beam to pass through the orbits and exit through the mentum. As a result, it highlights the maxillary sinuses located laterally to the nasal cavity, making it an essential projection for diagnosing conditions related to these sinuses, such as sinusitis.

While other projections can demonstrate different anatomical structures, the Water's projection is particularly designed to emphasize the maxillary sinuses by minimizing the distortion of other surrounding structures and providing an unobstructed view. This makes it an invaluable tool in dental and medical radiology for assessing sinus health.
