Dental review; devoted to the advancement of dentistry. . on. I start my needle in the septum of gum between the teeth, ex- 382 THE DENTAL REVIEW. pressing a drop of the anesthetic here, then directing the needleto a point where I may force it well up between the alveolus andthe root of the tooth; and then, with considerable pressure lastingfrom five to eight minutes, force the novocain into the tissue. Caremust be taken to support the syringe so as not to vibrate it enoughto break off the point of the needle. This is done by using a restwith the left hand on the teeth and helping support the instrumentin this way. If this is done, one will get an anesthesia lasting about forty-rive minutes with a minimum amount of anesthetic expressed intothe tissue, which is to be taken into consideration. The less anes-thetic used,—and in this way about all that is necessary is fouror five drops of the novocain solution,—the better, for I do notbelieve it is well to see how much anesthetic—or any foreign sub-stance—we can express into the Fig. 1 Fig. 1-A and B will show the direction of the needle in mytechnique. We are now ready to grind down the incisal of our tooth. Toaccomplish this, we use a ^-inch rapid cutting stone, about ^-inchin thickness, giving to the incisal edge a plane which will receiveforce of incision at right angles to this applied force. (Fig. 2-A,B and C.) Only grind off incisally to a depth a little more than thedento-enamel junction. The mesial and distal are removed with a flat safe-sided sep-arating disk, and here one must keep in mind the fact that we mustnot cut off too much of either side, for we wish only to remove ORIGINAL COMMUNICATIONS. 383 enough to leave the sides slightly tapered after the shoulder is cut.(Fig. 3-A, B and C.)
