| Abstract: | Objective\ To examine the influence of RD denture cleansers on the strength of polymethyl methacrylate. Methods\ This study consisted of three groups: cleanser group, tap water group and blank group, 10 samples for each group. The samples were soaked in solution of RD denture cleansers and tap water for 240 hours respectively. Then the elastic modulus and the flection strength of each group were tested and analyzed by the ANOVA. \ Results\ There was no difference in the elastic modulus and the flection strength among the groups ( F=0.090,0.806,P >0.05). \ Conclusion\ The RD denture cleansers does not affect the strength of polymethyl methacrylate. |
