The aim of modern root canal treatment is to disinfect, shape and fill the complex three- dimensional root canal system of a tooth.

Modern endodontic treatment makes use of an ever-increasing toolbox of sophisticated diagnostic techniques, rotary instrumentation, disinfecting chemicals and filling materials to restore the health of the tooth and the surrounding bone. For a long time, certain American dentists have proposed controversial ideas about root canal treatments and their effects on a patient’s general well-being. Much of this research has been discredited in the scientific literature and their proponents dismissed as quacks and charlatans.
