What tool is specifically designed to widen the root canal?

1. Suture scissors

2. Gates glidden

3. Extraction forceps

4. Endo explorer

The correct answer is: Gates glidden

The tool designed specifically to widen the root canal is the Gates Glidden. This endodontic instrument is used during root canal procedures to increase the width of the canal and facilitate the removal of infected or damaged tissue. The design of Gates Glidden drills allows them to easily access and prepare the root canal system. They have a tapered shape and are typically made from stainless steel or NiTi, making them versatile for different canal shapes and sizes. Their primary function is to create a smooth, clean environment that can be effectively treated and sealed, making them essential in endodontic therapy. Comparatively, suture scissors are used for cutting sutures and would not be appropriate for widening root canals. Extraction forceps are tools designed for the removal of teeth and do not have applications within the root canal space. An endo explorer is utilized for locating canals and assessing the internal anatomy of the tooth, but it is not intended for widening the canal itself. Understanding the specific functions and designs of these instruments is crucial for effective dental practice.
