Dental Amalgam, Micro-hardness and BurnishingAbstract
The authors studied the micro-hardness of restorations of conventional and high copper amalgam alloys with the purpose of verifying the effects of burnishing, at the age of 24 and 168 hours. Our data show that the micro hardness values for all amalgams studied, increased with time. Furthermore, there was no statistical significant difference between the micro-hardness mean values in the two areas of the restorations. The micro-hardness values of high copper amalgam system are higher than the one of conventional alloys, considering both sites studied.
