The endodontic obturator comprises an obturation needle (1; 11) and a handle (2; 12) for positioning of the obturator, and is characterised in that said obturation needle (1; 11) and said handle (2; 12) are joined by means of rod (4; 14) breakable by turning said rod on its longitudinal axis. When the obturator is a central obturator said obturation needle (1) advantageously includes a locating head (3) fitted at the end of the obturation needle (1) in contact with said rod (4). Said head facilitates withdrawing the handle by simply turning it a few times. |
