Correct answer: D — Bitewing radiograph (vertical)
Vertical bitewing radiographs are the most useful standard radiographic technique for assessing interproximal alveolar bone height and detecting bone loss in periodontal disease. They show the relationship between the alveolar crest and the CEJ with minimal geometric distortion. Horizontal bitewings are standard for caries detection but may not capture the entire alveolar crest in patients with bone loss. Vertical bitewing orientation captures more of the root and crestal bone. A full-mouth periapical series may be needed for comprehensive assessment.
