title: Statistical analysis of the ability of police dental surgeons in identification of dental filling materials.
abstract: The subjects, 77 police dental surgeons at 50 police stations in Kanagawa prefecture, were asked to identify either gold foil filling, gold inlay, palladium alloy inlay, silver alloy inlay, which had been filled in 5 human skulls. We conducted a statistical analysis of the dispersion of agreement rates in identifying the filling materials according to their clinical career. The results showed that the rates for gold inlay and gold foil filling were higher than those for silver alloy inlay and palladium alloy inlay. However, it was concluded that caution is necessary in identifying elaborately-finished fresh filling materials.
