Abstract


Background:  A common practice for avoiding cross infection is the sterilization of all items contaminated directly or indirectly with blood or saliva. Aim: To evaluate and compare the  dimensional stability  of heat cure acrylic resin , when subjected to repeated microwave and chemical disinfection for the purpose of disinfection”  Materials and Methods: This study was carried out in the department of prosthodontics at Dr. D.Y.Patil dental college and hospital,pune. “To evaluate  and compare the dimensional stability of the maxillary heat cured denture base after disinfection from microwave and chemical disinfectant at 0, 7th ,15th, 30th day.” The cast with the record bases were tested at 3 points.  Point A , point B at hamular notches  and point C at the deepest point in the palate with the help of the. REICHERT ,OPTICAL MICROSCOPE (AUSTRIA ,SR.NO.363798).  Results: When multivariate ANOVA test was applied it shows there is no significant difference between the three groups.  Conclusion: There is no significant change in the dimensional accuracy of acrylic resin samples of test groups when compared to control group (C ) on 7th, 15th, and 30th day after disinfection.
