The “Endodontics” (root canal treatment) has developed rapidly in recent years. If the nerve of the tooth must be removed, his “cave” sampled with electronic measuring instruments and cleaned using special agents and disinfected.
Then, the channel is electrically extended and filled with sterile biological ceramic materila. A tooth may have up to five small root canals. To detect the tiny structures, I generally work with loupes or an operating microscope. Of course, under aseptic conditions.
