Which radiograph type shows the entire tooth from crown to root apex and surrounding alveolar bone?

• A. Periapical radiograph
• B. Bitewing radiograph
• C. Panoramic radiograph
• D. Occlusal radiograph

Answer: (A)

Showing the entire tooth from crown to root tip and the surrounding alveolar bone is what a periapical radiograph is designed to do. This view captures the full length of the tooth, including the apex, and the bone around it, allowing you to assess the root structure, the condition of the lamina dura and periodontal ligament space, and any periapical pathology or bone loss.

Bitewing images focus on the crowns of adjacent teeth and the height of the alveolar bone between them; they don’t include the full root length or the periapical region. Panoramic radiographs provide a broad view of the entire dental arch, but with less detail at the roots and potential distortion, so they’re not ideal for evaluating the precise periapical area of a single tooth. Occlusal radiographs are used for other purposes, such as viewing the floor of the mouth, nasal area, or large sections of the jaw, and they don’t consistently show the full tooth length with its surrounding periapical bone.
