A little set of two unsigned toothkeys made in steel and horn and a quite early example, unsigned, of this unusual double dental elevator, called by Garengeot “repoussoir” but more generally called “pied de biche” and used for roots.
According with Bennion, the double dental elevator was used in this way : “The upper branch was intended to displace roots, the lower to raise the roots to the outside” (Bennion, page 41).
The elevator is in great condition with a wood handle, not ebony, with only a little crack.
The two toothkeys are in general good condition excepted a small lack of horn on each handle ;
They measure 13,5×9,7 cm and 13×11,4 cm ; the elevator 13,3 cm lenght.
