Rubber stops play a crucial role in endodontic procedures by providing a visual indicator of the length of the root canal being treated. When a dentist or endodontist measures the length of the root canal with a file or other instruments, they place a rubber stop on the instrument. This allows them to maintain a consistent depth during the procedure and helps ensure that they do not extend beyond the apex of the root. Accurate measurement is vital for effective treatment and to prevent complications such as over-instrumentation or under-preparation of the canal, which could affect the success of the root canal therapy.

In this context, the other options do not accurately reflect the function of rubber stops. They do not indicate the total depth of the tooth root, the type of anesthetic to be used, or the measurement for filling material. Each of these aspects is managed through different protocols and tools specific to their functions in dental treatment.
