What is the minimum number of radiographs needed for an endodontic procedure?

In endodontic procedures, the minimum number of radiographs typically needed is two. The first radiograph is usually taken to assess the initial condition of the tooth and to visualize the anatomy of the root canal system before treatment begins. This image helps the dentist determine the extent of the infection, the shape and length of the root canals, and any other anatomical considerations that may be present.

The second radiograph is generally taken after the cleaning and shaping of the canals to confirm that they have been adequately prepared and that no remaining debris or infected tissue is present. This image is crucial for verifying the working length of the canal and ensuring that the filling material can be placed effectively.

In some complex cases, additional radiographs may be required, but two is the standard minimum for ensuring a thorough assessment and guiding the treatment process.
