Which radiographic view is commonly used to assess the proximal surfaces of posterior teeth?

• A. Maxillary Anterior Periapical
• B. Mandibular Anterior Periapical
• C. Bitewing
• D. Maxillary Posterior Periapical

Answer: (C)

Proximal surfaces of posterior teeth are best seen on bitewing radiographs because this view is designed to capture the crowns of both upper and lower posterior teeth together and clearly show the interproximal contact areas. By positioning the sensor between the teeth and directing the beam to image the crowns while the patient bites on a tab, the contact points are opened in the image, making it easy to detect interproximal caries and assess bone height at the crestal level. Other views focus on tooth roots or anterior regions and do not optimize visualization of the proximal contacts between posterior teeth, so they’re less effective for evaluating those surfaces.
