Additionally, the endodontic brush includes a spiral wire at least partially surrounding the core and extending to the tip of the core opposite the end of the tip. Tip protrudes beyond the spiral wire at the end opposite to the end of the tip, and the tip is cut along a line directed at angle of 10 to 80 degrees to the axis of the core to increase the area of contact between the strands and the walls of the root canal of the tooth.
