Answer to Vol 234 Issue 4: Originally designed by Savigny in 1798, this later version of an extraction tool with ebony handle, brass shaft and steel serrated end was reasonably effective in removing the retained roots of fractured anterior teeth. By rotating the handle, the serrated end cut its way down the periodontal membrane of the tooth, thereby opening a gap between the root surface and surrounding alveolar bone. The spike, or pulp pin, would be forced down the pulp canal at the same rate as the trephine advanced along the root surface. For a very long straight root, the spike could be further extended by adjusting the sliding side screw, thereby giving the instrument greater ‘tugging’ power. Brian Williams – BDA Museum volunteer.
