Which instrument condenses gutta-percha points in the root canal during endodontic treatment?

• A. gates-gidden bur
• B. spreader/plugger
• C. endodontic spoon excavator
• D. hand files

Answer: (B)

The instrument used to condense gutta-percha points in the root canal during endodontic treatment is the spreader/plugger. These instruments are specifically designed to compact and adapt the gutta-percha to the canal walls effectively.

The spreader is typically used first to create space for additional gutta-percha points and to ensure that the material is tightly packed, which helps achieve a proper seal and prevents future reinfection. The plugger is then utilized to further compact the gutta-percha into the canal, ensuring that there are no voids or air bubbles that could compromise the success of the root canal treatment.

The other instruments listed, such as the gates-glidden bur, are primarily used for canal preparation rather than for condensing gutta-percha. The endodontic spoon excavator is designed for removing decay or debris from the cavity but is not intended for use in the root canal filling process. Hand files are essential for shaping and cleaning the canal but do not condense the filling material. Thus, the spreader/plugger is the correct choice for the specific task of condensing gutta-percha during endodontic procedures.
