for each root canal of the plurality, connecting a negative pressure irrigation needle (20) to a corresponding one of a tube (35) of a suction manifold (37);
inserting each negative pressure irrigation needle into a corresponding root canal of the plurality, the negative pressure irrigation needles being spaced from the suction manifold;
sealably surrounding a portion of each negative pressure irrigation needle adjacent the human tooth with a first light-cure polymer in an unpolymerized state;
connecting an irrigant inlet tube (41) to an irrigant container (33);
inserting the irrigant inlet tube into the human tooth, the irrigant inlet tube spaced from the negative pressure irrigation needles;
sealably surrounding a portion of the irrigant inlet tube adjacent the human tooth with a second light-cure polymer sealably in an unpolymerized state; and
maintaining a closed vacuum system when:
drawing irrigant through the irrigant inlet tube into the plurality of root canals containing the negative pressure irrigation needles;
suctioning the irrigant down each root canal of the plurality; and
