【摘要】 ①目的　检测RD义齿清洁剂对聚甲基丙烯酸甲酯树脂材料强度的影响。②方法　本实验分为清洁剂组、自来水组和空白组 3组 ,每组 10个式样。将受测式样分别用RD义齿清洁剂、自来水浸泡 2 40h后 ,测量各组式样的弹性模量和挠曲强度 ,结果行方差分析。③结果　受测式样的弹性模量和挠曲强度各组间比较差异无显著性 (F =0 .0 90 ,0 .80 6 ,P均 >0 .0 5 )。④结论　RD义齿清洁剂对聚甲基丙烯酸甲酯树脂材料的强度无影响更多还原

【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.更多还原
