Abstract
Abstract This plate for packaging dental root-canal instruments comprises a support formed with recesses adapted to receive the instruments and a protection cover which is a slide fit on the plate. The recesses consist of parallel elongated cavities extending at a short distance from, and at right angles to a longitudinal edge of the support, and comprise each an extension in the form of a neck towards the opposite longitudinal edge. The support also comprises a flat central area somewhat recessed in relation to the bottoms of the necks in order to facilitate the gripping of the instruments' shanks.
