What is the most common type of dental radiograph used to assess caries?

The bitewing radiograph is the most common type used to assess dental caries due to its specific design and purpose. Bitewing radiographs capture the crowns of the upper and lower teeth, providing a clear view of interproximal areas where caries often develop between teeth. This type of radiograph allows for effective identification of decay that might not be visible during a clinical examination alone.

The bitewing technique also helps in monitoring the progression of carious lesions over time, making it an essential tool for preventive dental care and treatment planning. Additionally, its placement is less invasive and comfortable for the patient compared to other types, which can be critical in routine evaluations.

In comparison, panoramic radiographs provide a broad overview of the entire mouth, but they are not detailed enough to detect early carious lesions effectively. Cephalometric radiographs are primarily used in orthodontics for evaluating tooth relationships and skeletal structures, while periapical radiographs focus on the entire tooth and surrounding bone but are less effective than bitewings for detecting caries specifically between adjacent teeth.
