Which radiograph is used for diagnosis of pathological conditions of the teeth during endodontic procedures?

The correct choice is the periapical radiograph, which is specifically designed to provide a detailed image of the entire tooth structure, including the roots and the surrounding bone. This type of radiograph is particularly useful during endodontic procedures, as it allows the dentist to visualize the tooth's root canal system and any associated pathological conditions, such as abscesses or periapical lesions.

By capturing detailed images of the apex of the tooth and the surrounding periapical area, the periapical radiograph enables accurate diagnosis and effective treatment planning for endodontic issues. It is ideal for assessing the extent of infection or damage to the tooth structure, which is critical for procedures like root canal therapy.

The other types of radiographs, while useful for different diagnostic purposes, do not provide the same level of detail in the context of endodontics. Bite-wing radiographs primarily capture the crowns of adjacent teeth and are used to detect interproximal caries and assess bone levels. A full mouth survey encompasses a variety of exposures, including periapical and bite-wing images but may not focus specifically on endodontic conditions. Occlusal radiographs are used for visualizing larger areas of the dental arch and can capture the positioning of teeth
