DANB General Chairside Practice Test

Which instrument is specifically used to adapt and condense gutta-percha points during endodontic treatment?

1. Rotary file

2. Spreader or plugger

3. H-file

4. Explorer

The correct answer is: Spreader or plugger

The specific instrument used to adapt and condense gutta-percha points during endodontic treatment is the spreader or plugger. These instruments are designed to handle the soft, thermoplastic nature of gutta-percha when it is heated, allowing dental professionals to effectively compact and shape the material within the root canal system. The spreader is typically used to laterally compact gutta-percha, helping to adapt the material against the walls of the canal and eliminate voids, while the plugger is employed for vertical condensation, ensuring a tight and secure fill. This is critical for achieving a good seal, preventing reinfection, and promoting healing after an endodontic procedure. In contrast, other instruments mentioned may serve different purposes in endodontic treatment. Rotary files are used for shaping and cleaning the canals, H-files help with the removal of debris, and explorers are primarily used for detection purposes rather than the adaptation or condensation of filling materials. Understanding the specific roles of these instruments is essential for effective endodontic practice.
