Abstract
Aim: The purpose of this study was to evaluate the impact of silver nanoparticle incorporation into maxillofacial silicone material on its hardness tear strength and color stability. Methodology: A total of 90 silicone specimens were fabricated. The control samples were fabricated with- out silver nanoparticles and test samples were fabricated with 20 ppm concentration of silver nanoparticles. Digital shore A hardness tests was used to measure hardness, for tear strength the specimen was placed in the jaws of the universal testing machine and stretched at a rate of 500 ram/rain, for color stability Spectrophotometer had been employed. The independent sample’s “t” test was used to test significant differences. Results: The mean difference for hardness between control and test group was 0.54 and t value was 2.08 and ( p < 0.05).tear strength 0.66 and “t”value was 0.93 and ( p < 0.05) and for color stability it was -0.02 and t value was -0.92 and ( p < 0.05). Conclusion: The present study findings suggest that addition of silver nanoparticles at 20 ppm concentration decreased the hardness of silicone elastomer, and it did not affect tear strength and color stability.
