In which scenario would you use an occlusal X-ray?

An occlusal X-ray is specifically designed to capture a broader view of the entire arch of teeth and their relationship to the jaw. This type of radiograph is particularly useful in situations where a comprehensive understanding of the dental and skeletal structures is needed. It helps in assessing the positioning of all teeth within the dental arch and is also valuable for viewing the layout of the maxilla (upper jaw) and mandible (lower jaw) in relation to one another.

In contrast, the other scenarios focus on narrower aspects of dental health. Checking alignment (the first option) primarily requires a different type of X-ray, typically a panoramic or cephalometric view. Isolating views of individual teeth (the third option) would generally necessitate periapical or bitewing X-rays, which are focused on specific areas rather than the entire arch. Detecting fractures in the crown (the fourth option) again usually demands targeted radiographic techniques that concentrate on individual teeth. Hence, for overall assessment of the jaw and teeth relationships, an occlusal X-ray is indeed the appropriate choice.
