Dentsply ProTaper Next Refill 21mm is a dental product that includes a set of files used in root canal treatment. These files are designed to be used with the ProTaper Next system, which is the successor to the ProTaper Universal system. The ProTaper Next system is known for its versatility and flexibility, providing efficient solutions for endodontic practitioners. The off-centered rectangular cross-section of the ProTaper Next files gives them a unique “swaggering” movement as they navigate through the root canal. This design, along with the off-centered cross-section and unique file design, creates an enlarged space for debris removal during the root canal procedure. One of the key features of the ProTaper Next files is the M-Wire NiTi (Nickel Titanium) material used in their construction.
