What if I can´t reach the working length with the 25/06 Sendoline S1 Plus file?

Use the Sendoline S1 Small file in cases with very narrow canals if the Sendoline S1 Plus (25/06) file does not reach working length. After reaching working length with the Sendoline S1 Small file, finish the preparation with the Sendoline S1 Plus (25/06) file.
