Endodontic hand files are instruments used during endodontic treatment to mechanically prepare root canals.
Avue H files are used to grasp canal obstructions and deliver them coronally through application of an upward force.The Angle between the cutting groove and the long axis of the Avue H file is generally in the range of 60-65 degrees.
This property helps in making them safe while working with canals having steep curvatures.
H-files are specially designed for shaping canals after they are previously cleaned and enlarged with K-files in root canal treatment. The H file can effectively enlarge the canal during filling motion
The Angle between the cutting groove and the long axis of the K file is generally in the range of 25-40 degrees.
