The Effect of Chemical (Glutaraldehyde ) And Microwave Sterilization On Impact Strength of Autopolymerizing ( PMMA ) Resins.

This study evaluated the effect of sterilization methods on the Impact strength of a self cured resins. A 10 hours immersion in 2 % alkaline glutaraldehyde, 15 minute exposure to microwaves energy was employed as a sterilization procedure. Storage in water for 10 hours was used as control. For each procedure 10 specimens were used. Results indicated that impact strength of the two groups did not change significantly as compared to control. Microwave sterilization can be opted as effective method and time saving procedure than immersion in chemical solution.
