Which type of film is specifically designed for detecting cavities in interproximal areas?

Periapical film is specifically designed to capture detailed images of the entire tooth, including the area around the apex (the root tip) and surrounding structures. This type of film is highly effective for diagnosing interproximal cavities because it allows the dentist to see the contact areas between adjacent teeth clearly. The close positioning of the periapical film relative to the teeth provides a clearer and more comprehensive view of the tooth structure, making it easier to identify decay, bone issues, and other dental conditions that may not be visible through visual examination alone.

In contrast, occlusal films are primarily used to view the occlusal surfaces of the teeth and to evaluate larger areas of dental anatomy. Panoramic films capture a broad view of the jaw and teeth, making them useful for overall diagnosis but not ideal for inspecting interproximal areas specifically. The mention of "Occusal film" may seem redundant, as it appears to be a typographical error for "occlusal film," reinforcing the notion that the periapical film is the most suitable choice for detecting cavities specifically located between teeth.
