摘要
目的 :探讨影响白念菌粘附于硅橡能力的因素。方法 :对 C.albicans在两种硅橡胶材料表面粘附量进行计数 ,统计。结果 :SY- 1和 MDXA- 42 10在有无唾液获得膜存在条件下 ,白念菌粘附数量无显著差异 (P>0 .0 5 ) ;在有唾液获得膜存在时 ,各种材料表面的白念菌粘附数量明显低于无唾液获得膜存在时 (P<0 .0 1)。结论 :C.albicans对两种硅橡胶材料的粘附性无明显差异 ,唾液的存在有降低 C.albicans粘附的作用。
砄bjective:To compare the adherent ability of Candida albicans on the surface of two kinds of silicone elastomer used as prosthodontic materials and to study the factors affecting the adherence.Methods: Candida albicans were cultured on the surface of SY 1 and MDXA 4210 with or without saliva acquired pellicle for 10 min, then the number of the bacteria was counted.Results:With or without saliva acquired pellicle,the number (1×10 3/mm 2) of C.albicans on SY 1 was 24.5±0.88 and 2.0±0.47 respectively( P < 0.01 ),and that on MDXA 4210 was 22.1±0.96 and 1.8±0.43 respectively ( P <0.01).There was no significant difference between the adherence of C.albicans on the two materials in the two conditions ( P > 0.05 ).Conclusion:There is little difference between the adherent ability of C.albicans on the two kind of silicone elastomer.Saliva acquired pellicle can decrease the adherence.
