A total of 50 specimens were fabricated for each of Filtek Z 250, Clearfil ST, Aelite LS Packable according to the manufacturers' instructions. Ten specimens of each material were randomly selected and stored in 8% ethanol, 50% ethanol, heptane, distilled water, and air at 37 degrees C for 1 week. After one week conditioning period, hardness testing was carried out with a micro hardness tester. The hardness of composite resin materials are strongly influenced by food simulating solutions.en10.1177/0021998307086205info:eu-repo/semantics/closedAccesscomposite resinhardnessfood simulating solutionsdegradationArticle4216975Q2WOS:000252740700004Q2
