Peregrination of endodontic tools-past to present

[摘要] The clinical practice of yesterday«SQ»s endodontics becomes the heresy of today, and today«SQ»s endodontic practice becomes the heresy of tomorrow. The history of endodontics begins in the 17 th century. Since then, there have been numerous advances and developments, and research has proceeded continuously without pause. The manufacture of the first instruments for endodontic use dates back to 1875. These early instruments were made by hand from thin steel wires, and they performed the function of modern barbed broaches. In 1955, Ingle was the first to express the need for standardization of canal instruments. In 1965, the American Association of Endodontists adopted the terminology and nomenclature of the proposed standardized system. For many years, the standard cutting instruments have been the reamer, the K-type file, and the Hedstroem file. Recent changes in both metallurgy and endodontic concepts have led to the introduction of a wide range of new instruments. An effort has been made here to present the journey of endodontic instruments from the past to the present.
