Abstract
Background and Methods:: Evaluate the effects of antiviral hydrogen peroxide in different percentage (1%, 2%, 3%) applied at different time intervals on commercially pure titanium surfaces in prostheses and calculate the amount of titanium ions release, eighty of commercially pure titanium samples were divided in to (4) groups according the concentration of hydrogen peroxide that exposed to different time interval (5 ,10,15,30) mint as aging time, cpTi samples were coded, the quantities of ions released of (Ti) were measured for each solutions, after the immersion time was finished. Result: After immersion time, (Ti) ion release in solution with (1% H2 O2) present in small amount in of all exposure time, while 3% H2O2 solution (Ti) ion release in large amount when compare with control (immersed in deionize water) when compare between four immersion solutions after various immersion times, a statistically significant difference occur at (p ≤ 0.05). Conclusion: Antiviral hydrogen peroxide usage as a therapeutically agent in different concentration and immersion in different time lead to release of ions (toxic ions), release of (Ti) ions increase with the more in the (H2O2) concentration and increase in the time of exposure to it.
