ResumoThis study was designed to develop an indirect method for measuring the time required for restoration placement; and to compare the operator time required for placement of amalgam and composite resins in posterior teeth in children. Forty children, aged seven to nine years old, were selected to participate. Either amalgam or an experimental resin was used to restore the primary and permanent molars. All restorations and sealants were completed under the rubber dam. Each restorative appointment was videotaped with a color video camera mounted on the ceiling. Ninety-six restorative procedures were reviewed and evaluated for the amount of time necessary to accomplish them. The Class I permanent molar composite restoration required 35 percent more insertion and finishing time than did the amalgam.
