PoFile (profiles) is a new type of nickel-titanium (NiTi) rotary endodontic instrument. Four features distinguish them from standard tools. First, they are made of nickel-titanium alloy, which gives them high ductility and allows processing of the channel with bending up to 90 °. Secondly, the files have a taper of 4 and 6%, which ensures safe operation. The third feature is a U-shaped cross section without pronounced cutting edges, which allows you to remove sawdust from the root canal. The fourth is a modified (blunt) tip, through which the tool can penetrate into the channel without creating additional direction (perforation).
ProFile® tools, introduced in 1996, are as secure as possible due to non-cutting radial flat edges and a U-shape in cross section.
ProFile®’s multiple taper, ranging from 2 to 8%, allows you to successfully complete the entire root canal using the crown-down technique.
The increased flexibility of the finishing files allows you to gently form the root canal, especially in the apical third.
