The opening of the root canal system is followed by the preparation of the root canals. Given that most bacteria are found in the coronal third of the root canal, it is particularly important to clean this section of the canal right at the start, making sure that the subsequently used files do not spread the bacteria towards the apex. This step has the added advantage of facilitating the work of the next files and improving the dentist’s field of vision. Komet provides a vast line of instruments for this, from the well-established Gates-Glidden burs to openers.

These files for the mechanical preparation of root canals are provided with a short working part and large taper to facilitate particularly efficient work.
