Abstract
In this study, the retention of composite resin and amalgam by a smooth, reverse-tapered pin was compared to that of threaded pins. The smooth pin was significantly lower in retention than the threaded pins for each material, and caused a greater frequency of failure of the restorative material than the threaded pins. The newer smooth pin is probably not an improvement over the conventional threaded design.
