An endodontic instrument for the irrigation of a dental radicular canal accompanied by aspiration of reflux liquid from said canals comprises at least two separate inlet ducts for irrigation liquid, and a third or outlet duct for aspiration of liquid reflowing from the irrigated radicular canals. It comprises further a needle holder head having two inner chambers, one communicating with the inlet ducts and the other one with the outlet duct. The head carries, firmly fixed thereto, a hollow needle for conveying the irrigation liquids to the radicular canal. The head has moveably fitted thereon an aspiration spout coaxial to the needle and movable in both directions with respect to the needle, as to make it possible to vary the depth of penetration of the needle into the radicular canal while the aspiration spout remains in a fixed position at the opening of the pulp cavity of the tooth.
