What type of radiograph is used to diagnose periodontal disease and endodontic therapy?

The periapical radiograph is highly effective for diagnosing periodontal disease and evaluating endodontic therapy because it provides detailed images of the tooth roots and the surrounding bone structures in a localized area. This type of radiograph captures the entire tooth, from the crown to the apex, which allows for the assessment of periapical pathology, root fractures, and the condition of the surrounding periodontal tissues.

Additionally, periapical radiographs help in identifying bone loss associated with periodontal disease, as they clearly illustrate the relationship between the tooth roots and the alveolar bone. In endodontic therapy, these radiographs assist in determining the length of the root canal and evaluating the success of treatment after the procedure.

Other types of radiographs, such as panoramic and bitewing radiographs, provide different views and types of information, but they do not offer the same level of detail regarding the roots and adjacent bone structure that is critical for diagnosing periodontal and endodontic conditions. Cephalometric radiographs are primarily used in orthodontics and to analyze the relationships between teeth and skeletal structures, making them less relevant for diagnosing these specific dental issues.
