a) When the indicating bar reaches the position of the dial 0.0[Picture 7(a)],

anatomical apical foramen. On the basis of measured length, subtract 0.5-1.0 mm to
get the working length.
b) When the indicating bar reaches the red area "OVER"[Picture 7(c)], it indicates
that the endo file has exceeded the apical foramen.
