MicroMega B5 HyFlex Remover 19mm N30 7% Classics 5pk

File to remove obturation materials from the root canal during non-surgical endodontic retreatments. Rationales for retreatment may be an endodontic failure during initial procedure, a reinfection in the tooth (new decay), a broken crown, a treated tooth that sustains a fracture, or in case an existing restoration must be redesigned. Retreatment involves reaccessing the pulp chamber and removing the 3D intra-canal obturation materials before proceeding to the the new roots treatment. No solvent required.
