Bitewing radiographs essential for periodontal assessment because they visualize which structures?

• A. Interproximal surfaces, crestal bone height, and proximal caries.
• B. They visualize the entire tooth root.
• C. They assess occlusal contacts.
• D. They replace periapical radiographs.

Answer: (A)

Bitewing radiographs are used for periodontal assessment because they show the interproximal surfaces and the crestal bone height along the proximal contacts. This view lets you see how high the alveolar bone sits relative to the cementoenamel junction, making it possible to detect early bone loss and monitor changes over time. In addition, bitewings reveal proximal caries, which can influence periodontal health and treatment planning. They do not show the full tooth roots or apices, so they aren’t used to evaluate root morphology or periapical pathology, and they don’t replace periapical radiographs for that purpose. They also don’t assess occlusal contacts.
