DANB Radiation Health and Safety (RHS) Practice Exam

Which of the following is a key characteristic of the panorex film?

1. Captures only bitewing images

2. Shows the entire tooth and root structure

3. Exclusively for occlusal views

4. Only used for anterior teeth

The correct answer is: Shows the entire tooth and root structure

The panorex film, or panoramic radiograph, is specifically designed to capture a wide view of the entire dental arch in a single image. This includes not only the teeth but also the surrounding structures, such as the jawbone and the sinuses. A key characteristic of the panorex film is its ability to show the entire tooth structure, including the crown and roots, which is crucial for diagnosing various dental conditions and planning treatments. This comprehensive view allows dental professionals to evaluate the alignment of teeth, assess jaw conditions, and plan for procedures such as extractions or orthodontics. In contrast, the other options do not accurately describe the panorex film's capabilities. For instance, it does not capture only bitewing images, which are a specific type of radiograph used to view dental decay between the teeth and to assess the bone level supporting the teeth. It is not exclusively for occlusal views, which focus on the bite of the teeth, and it is certainly not limited to anterior teeth, as the panoramic view encompasses both the anterior and posterior teeth, providing a full perspective on the patient's oral health.
