The meter numbers 1.0, 2.0, 3.0 and digital numbers 00-16 do not
represent the actual length from the apical foramen. It simply indicates
the file progression towards the apex. The digital numbers -1 and -2
indicate that the file has passed the apex foramen. The digital number “00”
indicate that the file has reached the apex foramen. Subtract 0.5-1mm
from the measured file length as the working length. These numbers are
used to estimate the canal’s working length.
