42 samples were stored in distilled water at 370 C for 48 ± 2 hours. Micro hardness measurements were made for all samples with Vickers hardness tester using a 25 - gf load for 10 seconds (VHN before disinfection).The diagonals of the pyramid impressed on the sample by the Vickers diamond indentor were measured and noted.
