Amalgam retention using pins, boxes, and Amalgambond.
The purpose of this study was to evaluate and compare the retentive strength of amalgam to tooth structure by utilizing pins, boxes, Amalgambond adhesive only, and Amalgambond adhesive plus retentive boxes. There was no statistical difference (P = 0.05) in retentive strength of the amalgam between the group utilizing pins alone and the group utilizing Amalgambond plus retentive boxes. However, both of these sample groups demonstrated statistically greater retentive strengths than either the boxes only or Amalgambond only groups.
