Main use of bitewings?

• A. Evaluate root canal
• B. Detect root fractures
• C. Periodontal bone loss & interproximal caries
• D. Assess occlusal wear

Answer: (C)

Bitewings are designed to show the crowns of the upper and lower teeth and the height of the alveolar bone between them. This view makes it the best tool for seeing decay that occurs between adjacent teeth (interproximal caries) and for monitoring periodontal bone loss by assessing the crestal bone level around those teeth. It’s not the ideal view for evaluating root canal anatomy or pathologies (that’s what periapical radiographs are for), and root fractures or occlusal wear are better assessed with other imaging or clinical examination.
