Bitewings are taken at a horizontal angle to reduce distortion.

• A. False
• B. They are not used for bone loss
• C. True
• D. They only show posterior teeth

Answer: (C)

Angle matters in bitewing radiography because it determines how faithfully the teeth and the spaces between them are represented. A horizontal angulation directs the X-ray beam through the contact areas, minimizing overlap and reducing distortion of the interproximal surfaces. This orientation, with the film kept parallel to the teeth, yields a true view of bone levels around posterior teeth and helps reveal caries between teeth. If the angle shifts vertically or diagonally, the contacts may appear distorted or overlapped, compromising diagnostic value.
