What type of drills are used in the low-speed handpiece?

The use of Gates-Glidden drills in low-speed handpieces is appropriate due to their specific design and function in dental procedures. Gates-Glidden drills are particularly effective for access preparation and the shaping of root canals. They are typically used with low-speed handpieces because these drills require a more controlled speed to allow for precision and efficient removal of tooth structure without excessive heat generation, which is crucial when working within the delicate confines of the root canal system.

Furthermore, low-speed handpieces are generally utilized for procedures requiring a gentle touch or when less torque is necessary. Gates-Glidden drills, characterized by their elongated, tapered design, help dentists navigate the curved anatomy of root canals, making them a preferred choice in endodontic treatments. The other types of drills mentioned have their own specific applications but do not align as well with the characteristics and intended use of low-speed handpieces.
