The Effect of Chemical (Glutraldehyde ) And Microwave Sterilization on Flexural Strength Autopolymerizing (PMMA ) Resings.

ABSTRACT

This Study evaluated the effect of disinfection methods on the Flexural Properties of Auto Polymerizing Resin. (Tooth Colored and Repair Resin). Specimens were exposed to microwaves for 15 min and 2 % Glutaraldehyde for 10 hours. Specimens stored in Water for 12 hours were used as control. For each procedure 10 specimens were used. The result indicated that changes in Flexural Strength observed were of no significance for both Tooth Colored and Repair Resin. The Microwave method is useful alternative to immersion disinfection having advantage of less time consumption.
