Comparative study on effect, denture cleanser and disinfectant have on flexural strength of PMMA

AUTHOR(S): Vidya Bhat S, Karkala Sayed Suhaim, K. Kamalakanth Shenoy
ABSTRACT:In selecting a disinfectant for dental prosthesis, compatibility between the disinfectant and the type of denture base material must be considered to avoid adverse effects in the acrylic resin. In this study a total of 75 specimens of heat cure acrylic of dimension (65x10x3) mm were prepared. 15 specimens were immersed in distilled water, used as control and 60 samples were treated. 30 were treated with 4.8% of sodium perborate (Fittydent ®) at 50 0C for 8 hours and 24 hours. The third group were treated with 2.45% alkaline glutaraldehyde (Cidex®) at 37 0C for 20 min and 1 hour. All the specimens were subjected to three point flexural load in universal testing machine. The findings were analyzed using one way Analysis of Variance (ANOVA). Acrylic resin selected for this study did not demonstrate any significant difference in flexural strength after immersion. As the flexural strength of the denture base resins remained unaffected, all immersion solutions evaluated in this study could be safely applied in everyday practice for the disinfection of dentures.
