Abstract EN
Background : Polymers are very rarely used in their form.
These modifications are carried out in order to improve the properties of polymers.
Recently silver have been used successfully as antimicrobial (medical and dental) biomaterials that can prevent caries and infection of implants.
The aim of the present in vitro study is to evaluate the effect of addition of silver nitrate to acrylic resin in different concentrations through several tests part of these are : The effect of this additive on impact strength, transverse strength, and tensile strength of AgNO3–loaded resin, and to assess any effect of addition of silver nitrate on coloration of acrylic resin.
Materials and methods : Different concentrations of silver nitrate (9.375, 15, 30, 60, 120, 150, 300, 600 and 900 ppm) were prepared from stock solution of 1000 ppm silver nitrate.
The specimens were prepared in accordance with the manufacturer's instructions and the tested silver nitrate solution was added to the acrylic resin powder and monomer in a fixed volume (0.2ml).
Controls devoid of silver nitrate were included.
Results : Fourier transform infra-red confirmed that there was no chemical bond between the Poly methyl methacrylate and silver nitrate.
There was insignificant increasing (P = 0.05) in impact strength observed when compared with control group.
In transverse strength test, significant reduction was show (P < 0.001).
While for tensile strength there was insignificant reduction with 9.375 (P = 0.05NS) and 15 (P = 0.42NS) ppm silver nitrate.
However, it was significant above 15 ppm (P < 0.001).
Darkening of silver nitrate-loaded resins were shown to be started with concentration of silver nitrateof 300 ppm and above.
Conclusions : The additions of silver nitrate to acrylic resins yield good color stability and mechanical properties, depending on the concentration of silver nitrate.
