The pin-amalgam restoration. Part I. A review

Abstract

A review of the literature indicates that the use of pins to support amalgam or cast gold restorations in advanced caries in posterior teeth is a quick and relatively inexpensive method of restoring teeth otherwise doomed to extraction. However, the use of pins demands a careful and skillful dentist who understands the morphology of these teeth and the proper use of the materials if injury to the pulp, accidental perforations, crazing of the dentin, and splitting of teeth are to be prevented. Until more objective and controlled studies are completed, the use of cemented pins vs. self-threading pins remains a matter of empirical and personal preference. It is clear that success in the use of any pin or pins depends more on the dentist's skill and judgment than on the particular type of pin technique used. In order to more objectively evaluate the use of pin-amalgam restorations, Part 11 of this study will analyze the results obtained in the Clinic at Tufts University School of Dental Medicine.
