**Core Concept**
Bitewing radiographs are a type of dental radiograph that provides a two-dimensional representation of the upper and lower posterior teeth and the interproximal areas. This radiographic technique is particularly useful for detecting caries between teeth, bone loss due to periodontal disease, and the height of the alveolar bone.

**Why the Correct Answer is Right**
Bitewing radiographs are ideal for monitoring interproximal caries, as they allow for the detection of lesions that are not visible on clinical examination. The X-ray beam is directed between the teeth, creating a shadow of the interproximal area on the radiograph. This technique is also useful for assessing the height of the alveolar bone and detecting periodontal bone loss. The use of bitewing radiographs in dental practice helps in early detection and treatment of dental caries and periodontal disease.

**Why Each Wrong Option is Incorrect**
**Option A:** Periapical radiographs are better suited for evaluating the entire tooth, including the crown, root, and surrounding bone, making them less ideal for monitoring interproximal caries.
**Option B:** Occlusal radiographs are typically used to evaluate the entire dental arch and are not as effective for detecting interproximal caries.
**Option C:** Panoramic radiographs provide a broader view of the dental arch but may not be as sensitive for detecting interproximal caries.

**Clinical Pearl / High-Yield Fact**
Bitewing radiographs should be taken every 6-12 months for patients with a high risk of interproximal caries, and more frequently for those with a history of caries or periodontal disease.

**Correct Answer:** C. Occlusal radiographs.
