All machine files have their own downward suction force, so doctors do not need to apply additional downward pressure during clinical operations. Use your fingers as a simple fulcrum to keep pulling, and pull every 1mm to 2mm forward. When encountering resistance, pull. It is also recommended to use a "brush" technique when pulling. During root canal treatment, root canal instruments should never be allowed to work in one position for a long time. When encountering resistance, pull along the root canal wall immediately.
🔍It is recommended to check the instrument before each use. The manufacturer recommends checking whether the thread has changed before each use. Once unthreading (there will be obvious thread changes) and reverse threading are found, excessive use is not recommended. At this time, the chain structure has been damaged, which will increase the probability of instrument separation. It is strictly forbidden to skip numbers in root canal treatment. EDTA and sodium hypochlorite should be used in sequence according to the correct parameters. After flushing with the syringe, use the chain 10# file by hand to break up the debris blockage caused by flushing, fully flush and clean the debris on the file, and use accurate torque speed.
