Abstract
Abstract A finger pad for utilization in connection with angled dental instruments such as pluggers, margin trimmers, enamel hatchets, etc. The finger pad includes a piece of plastic or similar material mounted on the angled portion of the instrument and provided with pressure points contoured into the pad for reception of the tip of the operator''s finger. The contoured portions are positioned so that a direct pressure is properly directed toward the tip of the tool thereby eliminating inaccuracies. The pad can either be removably placed on the angled portion of the tool, permanently secured to the end of the tool handle or made integral therewith.
