The effects of certain disinfectants on the stability of a polymethyl methacrylate denture base resin were investigated, including those of a novel disinfection method using excited-oxygen. The following disinfectants were tested : 5% sodium hypochlorite, 70% alcohol, and excited-oxygen. Furthermore, the attachment of Candida albicans to the resin surface was investigated. The surface roughness and flexural strength of the excited-oxygen treated specimens did not significantly differ from those of the control specimens, and the excited-oxygen treated specimens exhibited diminished Candida attachment. These results demonstrate that the excited-oxygen disinfection method preserves acceptable material stability levels in polymethyl methacrylate resins.

研究了几种消毒剂对聚甲基丙烯酸甲酯义齿基托树脂稳定性的影响，包括一种新型的激氧消毒方法。测试了以下消毒剂：5%次氯酸钠，70%酒精和激发氧。此外，还研究了白色念珠菌在树脂表面的附着。激氧处理样品的表面粗糙度和抗弯强度与对照样品没有显著差异，并且激氧处理样品的念珠菌附着减少。这些结果表明，激氧消毒方法在聚甲基丙烯酸甲酯树脂中保持了可接受的材料稳定性水平。
