Waveone Gold Small, Primaly, Medium, Large File Dentsply 21mm, 25mm, 31mm 4files
The Small 21/06 file has a fixed taper of 6% over its active portion. Fortuitously, the Primary 25/07 file is generally the only file required to fully shape virtually any given canal. The WAVEONE GOLD system is a single-file and single-use technique.
