Silver point

The apical seal of silver points is rarely as good as their radiographic appearance would suggest, and in many cases the seal relies on the cement used. If this washes out, corrosion occurs leading to failure of the root filling. As a result the use of silver points is decreasing in popularity because of possible long-term failure problems. The radiographic aspect of a silver point obturated tooth can be seen in the thumbnail below, which can be clicked for a larger picture.
