Quantitative cultural studies of yeasts and bacteria were made from 1-week-old denture plaque accumulated on pieces of self-adhesive tape stuck on the fitting surface of the maxillary denture in four well-defined locations. A tape piece was also stuck on the buccal denture flange. The cultural examinations were made in 15 patients with denture-induced stomatitis which affected most of the denture-bearing mucosa. There was no significant difference of the bacterial counts from the different sampling areas although the variations between patients was significant. The yeast counts from the test area located on the buccal denture flange were significantly lower than those originating from the fitting denture surface. On the other hand, there was no significant variation of the yeast counts when comparing the test areas of the fitting denture surface. In 12/15 of the patients yeast counts of greater than or equal to 10(3)/cm2 were obtained from the fitting denture surface. The results indicate that the environmental conditions beneath a denture base predispose for yeast colonization and are different from those present on the buccal flange.
对15例患有义齿性口炎且大部分义齿承托黏膜受累的患者进行了定量培养研究，研究对象为积聚在上颌义齿贴合面四块明确位置的自粘带上的1周龄义齿菌斑中的酵母和细菌。在义齿颊侧边缘也粘贴了一条胶带。对义齿贴合面不同采样区域的细菌计数无显著差异，尽管患者之间的差异显著。义齿颊侧边缘测试区域的酵母计数显著低于义齿贴合面的酵母计数。另一方面，比较义齿贴合面的测试区域时，酵母计数无显著差异。15例患者中有12例在义齿贴合面获得的酵母计数大于或等于10(3)/cm2。结果表明，义齿基托下方的环境条件易导致酵母定植，且与颊侧边缘的环境条件不同。
