Intervention: Apical gauging
Description: Establish the depth of apical constriction - this is the zero reading on your apex locator. your working length will be 0.5mm - 1mm short of this.~After cleaning and preparing the canal system to your working length, passively insert 02 taper hand files, starting from #15. If the file goes past the apical constriction (your working length + 0.5-1mm), then choose the next largest file and repeat.~When a file passively binds short of the apical constriction, that will be the upper limit of the apical constriction diameter. The smaller file before that would be the lower limit.~Apical gauging helps with:~Choosing the best master cone that closely matches canal length and taper Achieving true tug back - as opposed to false tug back! Minimising gutta percha extrusions during obturation
