ABSTRACT:
The invention relates to an endodontic instrument which can be fitted on a vibratory handpiece (1) for the treatment of a tooth canal or the retreatment thereof, wherein it is made up of a rigid proximal portion constituting the sleeve which allows it to be fixed to the vibratory handpiece (1), of a median portion (4) which is also rigid and whose axis forms an angle (x) with the proximal portion, and of a distal portion (5) whose axis at the end forms an angle (y) with the median portion in the direction opposite that of the proximal portion, said distal portion being of a general conical line and of a dimension at the tip permitting its penetration into the canal.
