The cervical half of the cavity is shapedin the usual way, but instead of following the usual method of ob-taining anchorage for the occlusal half of the filling by drilling ob-liquely into the cavity between the plates of enamel \>hich givesus but a frail anchorage at best, one which is liable to fracture, re-sulting in dislodgment of the filling. I cut a groove leading fromthe cavity distally to near the center of the tooth, and in somecases I cut the groove entirely across the Fig. 2 Fig. 3 Fig. 4 This groove must be made deep enough ^nd wide enough tohold a sufficient amount of gold to give the necessary strength tostand all the force which may be brought to bear upon it in theact of mastication, and it should be made slightly deeper at thepoint furthest from the cavity which will greatly assist in bind-ing the filling in and more fully prevent its dislodgment. Some may object to the labial plate of enamel not being pro-tected more than represented, but by carefully beveling the cavitymargin and building gold over, it will be fully protected. In cases where the pulp has been freshly devitalized and thetooth healthy, the root canal offering such a place for good anchor-age, would cause me to save as much of the crown as possible. In cases where the pulp has been dead for some time and thetooth in a dry and brittle condition we will often do the patientbetter service by replacing the old tooth structure by an artificialcrown.
