The DG 16 was designed by Dr. David Green in 1951, who was from upstate New York. The instrument was designed in its present form because a straight explorer and a cowhorn (#23) explorer did not enable the endodontist to locate a vast majority of canal orifices, especially in the posterior teeth.
Endodontic Explorer DG 16 enables the clinician to better determine canal orifices and the angle of the canal orifice as the canal exits apically from the chamber.
