To do this we will use a cement syringe, which consists of a tubewith a piston working easily within it (Fig. i), and a contracted tubeor point at one end small enough to enter an enlarged canal that willreceive a pin; the cement is introduced into the syringe through alateral opening near the upper end. Mix the cement to the con-. sistency of thick cream or vaseline; if it is very quick setting, haveit thinner. Insert the small end of the instrument to the bottom ofthe canal; press upon the piston until you can see the cement comingout of the canal; continue to do this as you draw the point out of thecanal. The material is deposited at the bottom first, and the entirecanal is filled. Now insert the pin of your crown or bridge into the ce-ment and you have a perfect setting with no air confined at the end ofthe pin. How many times in setting a crown or bridge have wepressed it up to place only to find, after removing the pressure, it will 116 THE DENTAL REVIEW. come a little way out of the root and we are required to keep apressure upon it until the cement hardens enough to hold it does the crown start out?
