Fig. 330. A photograph of the direct quadrangle pliigger in action condensing a filling in the
mesial surface of a molar while the separator is in place. With this pair of instruments one is able
to obtain a direct stroke over any portion of the mesial surface. The picture also gives an excellent
exhibition of a half-reversed pen grasp.
