Den største utfordringen man møter innen endodontien, er at nesten alle kanaler er bredere buccolingualt enn mesiodistalt.
Hvordan kan man takle denne utfordringen og få en ren kanal?

XP-3D Finisher™ file — the next step in restorative endodontics
Drs. Martin Trope and Gilberto Debelian discuss reaching areas of the canal impossible with standard files.
The XP-3D Finisher instrument is a NiTi file No. 25 without taper, making it extremely flexible and resistant to cyclic fatigue. Below 30°C, it is in its pliable martensite form and can be straightened or manipulated to any shape. Above 35°C (body temperature), it transforms to its austenite phase and is straight until the last 10 mm where it has a spoon shape with a depth of 1.5 mm (Figure 4).
When rotating, this extremely flexible file has a natural diameter of 3 mm in the last 10 mm (Figure 5).
In addition, when the tip is squeezed, the bulb can be expanded to 6 mm; and when the bulb is compressed, the tip will expand to 6 mm.
