Which intraoral film types can show the apex of the tooth roots?

The question pertains to the types of intraoral films used in dental radiography, specifically which films can effectively capture the apex of tooth roots. The correct choice, which includes both periapical and occlusal films, is based on the purpose and design of these film types.

Periapical films are specifically designed to capture the entire tooth, from the crown down to the apex, including the periodontal structures surrounding the tooth roots. This makes them essential for diagnosing issues related to root tips, such as periapical abscesses or other pathological conditions at the root's apex.

Occlusal films, on the other hand, are larger and are used to capture a broader view of the dental arches. They can display the positions of multiple teeth and their roots, including the apices. While they primarily serve to visualize larger areas, they can still effectively show the apex of tooth roots, especially when the proper angling is performed during exposure.

In contrast, bite-wing films are primarily intended for interproximal examination of the upper and lower teeth, making them unsuitable for capturing the apex of tooth roots. They focus on the crowns of teeth and the alveolar bone, lacking the necessary coverage for root apices.

Therefore, the combination of periap
