Patient referred to the clinics with a separated hand file for non- surgical retrieval. Upon examination I found that the upper 6 had a 6mm long hand file in the MB canal extending beyond the apex.
-----------------------------------------
After coronal flaring using a mix of rotary files and GG burs a straight line access was obtained, and troughing on the inner wall was done using the E6 ultrasonic tip to try to loosen the file and half way through the troughing a secondary fracture occurred.
About 2 mm short of the apex the file started to loosen, after which the Leo pen was used to grip it and pull it out.
-----------------------------------------
Due to the apical violation of the previous work canal patency was achieved with #20 & #25 files in watch winding motion to reach the apex and create a glide path, Mechanical shaping done using M-pro files up to sizes #40 4% in P and DB and 25 6% in the last part of the MB canal to preserve that root.
Cleaning was done with NaOCl 5.25% with ultrasonic activation and intracanal heating.
-----------------------------------------
Finally, obturation was completed with CWC and resin sealer, except for the MB canal where first the apex was plugged with a down packed GP, then filled with MTA to enhance the fracture resistance of this root and a small flowable composite was placed on top of it to allow the MTS to set undisturbed.
