Principles and practice of operative dentistry . Cylinders and mats inthe act of being intro-duced into a crowncavity. dividual case as it is presented rather than to depend upon materialprepared in advance, as this is very rarely just what is required. TREATMENT OF CARIES BY OBTURATION, OR FILLING. 259 The cylinders or pellets are then placed in the cavity with foil-carriers(see Fig. 378), being arranged side by side around the circumference ofthe cavity and condensed against its walls with suitable pluggers. Othercylinders or pellets are placed in like manner, and these are condensedtowards its walls by the use of the wedging process, and this method con-tinued until the filling is finally finished by a single hard-rolled pelletforced into the centre. No instruments are better adapted for this purpose than those shownin Fig. 380, made from patterns furnished by Dr. Bing. Fig. Bing pluggers. The cylinders, if the filling has been properly introduced, should pro-ject a little above the surrounding tooth surface. These should now bethoroughly condensed by hand-pressure or the mallet. Large serrated,round-faced foot-pluggers, as shown in Fig. 381, are the best for this pur-pose, as pluggers with sharp angles are liable to pulverize the enamelmargins, if by chance they should come in contact with them. Thoroughcondensation, directed always towards the cavity walls, is of the utmostimportance in finishing the fillings. The surface should next be bur-nished, also towards the enamel margins, and the surplus gold cut awaywith finishing burs, stones, or the file, as the location of the filling maymake most convenient, and the surface polished with sand-paper disks,emery strips, and pulverized pumice-stone or rouge, or burnished. 260 OPERATIVE PENTISTRY, Many operators who use non-cohesive foil employ the hand mallet allthrough the operation in preference to the excl
