M Access K Files are high-quality stainless steel dental instruments specifically designed for use in endodontics, which is the branch of dentistry focused on root canal treatment. These files are essential tools used by dentists to clean and shape the root canals of teeth during the procedure. One of the notable features of Dentsply K Files is their unique cross-sectional designs. From sizes 6 to 40, the files have a square cross-section, allowing for efficient removal of debris and dentin from the root canal walls. For larger sizes, starting from size 45 and onwards, the files have a triangular cross-section, providing effective cutting and shaping capabilities in the more challenging areas of the root canal.
