Dental OSCE (Objective Structured Clinical Examination) Practice Exam

Which radiographic view is best for visualizing sinus structures?

1. Periapical view

2. Panoramic view

3. Waters view

4. Lateral cephalometric view

The correct answer is: Waters view

The Waters view, often referred to as the occipitomental view, is particularly well-suited for visualizing the paranasal sinuses, especially the maxillary sinuses. This radiographic view is achieved by positioning the patient's chin up and the X-ray beam directed at an angle through the occipital region, which allows for a clear view of the sinuses above the maxilla. In this view, the orbits, nasal cavity, and the maxillary sinuses can be seen in a way that shows their full extent and any potential pathologies, such as sinusitis or other abnormalities. This makes the Waters view a go-to choice for both diagnostic and treatment planning purposes related to sinus issues. The other options, such as the periapical view, are primarily used to visualize the roots of teeth and surrounding bone but do not adequately capture the sinus structures. The panoramic view provides a broad overview of the jaw and dental structures but lacks the specificity needed for detailed sinus imaging. Lastly, the lateral cephalometric view is typically employed for orthodontic analysis and craniofacial measurements rather than for direct visualization of sinus anatomy. Therefore, for the specific goal of evaluating sinus structures, the Waters view is the most effective choice.
