Case 2:
"Upper Right 1st premolar with a long piece of broken fragment blocking the way for thorough Cleaning and Shaping of the Apical Third. Creating space with the TFRK ultrasonic tips led to uneventful removal with the TFRK Loop+ Once the fragment was gone, Shaping and Cleaning to a 35/03 miniKUT was no problem."
Case 1:
Upper premolar with 3 canals, referred for the extra challenge in the mb-canal. Instrument removal with the TFRK Loop + and further apical refinement with the 3% tapered miniKUT system.
