What is the primary goal of using the Water's projection?

• A. To assess dental caries
• B. To evaluate sinus diseases
• C. To measure occlusal plane
• D. To check dental implant placement

Answer: (B)

The primary goal of using the Water's projection is to evaluate sinus diseases. This radiographic technique, also known as the occipitomental view, is specifically designed to provide a clear view of the maxillary sinuses as well as other paranasal sinuses, facilitating the assessment of conditions such as sinusitis or other inflammatory diseases affecting the sinuses. The positioning of the patient's head allows the X-ray beam to pass through the maxillary sinuses, which helps in identifying any pathological changes, fluid levels, or obstructions in those areas, making it particularly valuable for diagnostic purposes related to sinus issues. In contrast, the other options focus on different aspects of dental and anatomical evaluations. Assessing dental caries typically relies on periapical or bitewing radiographs. Measuring the occlusal plane is more pertinent to orthodontic assessments or prosthetic design, which may utilize other imaging techniques. Checking dental implant placement often requires specialized views such as panoramic radiographs or cone-beam computed tomography (CBCT) to provide comprehensive three-dimensional information about the implant site.
