Dental OSCE (Objective Structured Clinical Examination) Practice Exam

Which type of dental radiograph shows the highest level of detail for specific teeth?

1. Panoramic radiograph

2. Bitewing radiograph

3. Periapical radiograph

4. Occlusal radiograph

The correct answer is: Periapical radiograph

The periapical radiograph is considered to show the highest level of detail for specific teeth because it captures the entire tooth from the crown to the root, including the surrounding bone structure. This specificity allows for the identification of numerous dental conditions, such as infections, fractures, and bone loss, that might not be visible in other types of radiographs. Periapical radiographs are typically taken in a way that focuses closely on one or two teeth at a time, giving a clear view of the tooth's anatomy and any pathological changes. This makes them particularly useful for diagnosing issues that are related directly to the tooth and its supporting structures. The technique used in periapical radiography also minimizes distortion, providing a more accurate representation of the anatomical details. In contrast, other radiograph types, such as bitewing radiographs, primarily focus on the interproximal areas between posterior teeth, which may omit critical details of the roots and surrounding bone. Panoramic radiographs provide a broad, birds-eye view of the entire dental arch and surrounding structures but at the cost of detail, particularly concerning individual teeth. Occlusal radiographs are used to assess larger areas of the dental arch and are not as focused on individual teeth in the same way as per
