The Influence of Temperature on the Crushing Strength of Dental Amalgams

Abstract

Abstract

Investigation were made on the influence of temperature upon the crushing strength of amalgams, partly at elevated temperatures (Tables 1 and 2, Figure 1), partly after short heating and recording to room temperature (Table 3, Figure 2). Furthermore it was investigated how fast short-heated and recooled amalgam will recover strength (Table 4, Figure 3).

The experiments show that the strength is essentially reduced by increased temperature, and that the amalgam specimens regain their mechanical properties after a relatively short time.
