Abstract:

 Background: The aim of this study was to evaluate the effect of thermo cycling and different pH of artificial saliva(neutral, acidic, basic) on impact and transverse strength of heat cure acrylic resin reinforced of with 5% silanatedZrO2 nano fillers.Materials and methods: 120 samples were prepared, 60 samples for impact strength test and another 60 samples fortransverse strength test, for each test, samples were divided into two major groups (before and after thermo cycling),then each of these major groups were further subdivided into 3 subgroups according to the pH of prepared artificialsaliva (neutral, acidic, basic). Charpy impact device was used for impact strength test and Flexural device was usedfor transverse strength test.
Result: There was a non-significant difference between the two major groups (before and after thermo cycling). Alsoresults showed that there was a non-significant difference between the subgroups for each major group in referenceto pH of artificial saliva. These results were found in both impact and transverse strength.
Conclusion Transverse strength and impact strength of heat cure acrylic resin reinforced with silanated ZrO2nanofillers was not affected by thermocycling and different PH of artificial saliva suggesting improvement in themechanical properties.
