Without question, the TFRK ultrasonics and the EndoCowboy are the best tools currently available for dealing with unforeseen complications during endodontic treatment. From visualization and negotiation of deep bifurcations to removal of separated instruments, PlanB Dental provides the tools to treat cases confidently and efficiently. With the TFRK ultrasonics and the EndoCowboy in hand, I no longer feel limited by my equipment. When a separated file is present, if I can see it, I can remove it!

Case 1

Patient was referred for RCT #3. Diagnosis: PN/SAP. Access prep completed. Orifice opening completed with ProTaper Universal SX. While scouting for WL, a #10 hand file separated at the orifice of the MB1 canal. Sponge and Cavit placed and new radiograph made. Ultrasonics used to trough around file, using the MB2 canal as a guide until the MB2 canal joined the MB1. Doing this, tooth structure palatal to the file was removed and very little tooth structure along the outer edges of the canal required removal. During this process, about 3mm of the coronal portion of the file broke and was removed. At this point, I switched to the TFRK ultrasonics and continued until 2-3mm of the file was exposed and there was some mobility present. EndoCowboy 0.12mm used to lasso the file. File removed in its entirety without complication. Case completed without further complication. No additional visit necessary. Post-op PA showed minimal loss of tooth structure required for file removal.
