表1经Bartlett方差齐性检验，各均数两两比较得白色念珠菌对Co-Cr 合金色度只影响绿色 区域内值，而对明度和黄色无影响。
表2经Bartlett方差齐性检验，各均数两两比较得空白对照组与培养基对照组之间色度无差 异，实验组与空白组和培养基对照组色度有明显差别。白色念珠菌对Ni-Cr 合金色度有影 响。
表3经Bartlett方差齐性检验，各均数两两比较得空白对照组与培养基对照组铸钛修复 体色泽差异不显著。实验组与培养基组和空白组色度有显著差异。白色念珠菌对铸钛修复体 色度有影响。

3 讨 论口腔微生物的数量很多。于显微镜下计数每毫升唾液含有细菌4 300万至55亿，加之口腔环 境变化复杂，细菌间有相互作用，因此，整体研究微生物对修复体失泽变化没有特异性。目 前，口腔中常见修复体种类为Co-Cr合金、Ni-Cr合金，铸钛修复体。白色念珠菌是一种条 件致病菌，通常存在于正常人口腔、上呼吸道、肠道等部，当机体免疫功能或一般防御能力 降低，或正常寄居的微生物间相互作用失调，就容易引起念珠菌病〔4〕。而白色念 珠菌病多见于戴用修复体的患者〔5〕。
