What type of film is primarily utilized for diagnosing interproximal decay?

The type of film primarily utilized for diagnosing interproximal decay is Bitewing (BW) film. Bitewing radiography is particularly effective for detecting caries located between the teeth (interproximal areas) and assessing the bone level surrounding the teeth. This film type captures a view of the crowns of both the maxillary and mandibular teeth in the same film, allowing for clear visualization of the contact points and interproximal spaces.

Bitewing films are adept at showing early decay that might not be detectable visually during a clinical examination. Additionally, they can also help in observing any changes in bone levels caused by periodontal disease, making them a valuable tool for both diagnosing decay and monitoring overall dental health.

Other types of films, such as periapical, occlusal, and panoramic, serve different diagnostic purposes. Periapical films focus on the entire tooth, including the root and surrounding bone, which is helpful in endodontic assessments but less effective for interproximal views. Occlusal films give a broader view of the dental arches but do not specifically target interproximal spaces. Panoramic films provide a wide-angle view of the entire mouth and are useful for evaluating overall dental alignment and pathology but lack the detail needed for diagnosing
