Compared to needles with apical opening, a needle with lateral opening and blunt end will prevent any risk of damage at the apex of the tooth (acute desmondontitis), especially with a chronically infected tooth (eg.: widely opened apex), or when the apessification is not complete.
The small diameter of the opening allows enough water pressure to expel the debris from the canal.
Cleaning root canals without risking a perforation of the apex.
3 diameters available:
0.30 mm (purple), for thin canal irrigation.
0.40 mm (yellow) for medium-size canal irrigation.
0.60 mm (blue), for large canal irrigation (canines and incisives).
33 mm length, suitable even for upper maxillar canine.
Very flexible, to adapt to all canal morphology.
