manual endodontic file / Hedstrom / coronal preparation
LM’s endodontic hand files with large handles are supreme in ergonomics.
The blade on LM-Hedstroem files is milled instead of twisted like on other root canal instruments. Especially well suited to procedures where space is made for the root canal orifice (coronal flare). Hedstroem files are only intended for use with filing, back-and-forth preparation motions.
