Poor oral hygiene has been frequently suggested as a predisposing factor for oral candidal colonization, but the convincing evidence is lacking.
To assess and compare oral candidal colonization, both quantitatively and qualitatively, in groups of healthy dentate subjects with different levels of oral hygiene as determined by the plaque index (PI) and gingival index (GI) scores.
The concentrated oral rinse technique was used to isolate Candida species from 149 healthy dentate subjects. Candida species were cultured on Sabouraud's dextrose agar plates and identified by germ-tube test and the automated Vitek(R) system biochemical yeast card. According to the PI and GI scores, subjects were divided into different groups of oral hygiene level.
Candida species were isolated from 86 (57.7%) subjects. The prevalence of candidal carriage increased significantly as a function of age (P = 0.023), but was comparable between males and females (58.7% and 56.7% respectively; P = 0.87). Oral candidal carriage rate and density were not affected by the levels of dental plaque or gingival condition. The prevalence of oral candididal carriage was significantly higher in the subjects who were not using dental floss compared with those who were using dental floss (P = 0.032).
Oral hygiene status, as determined by the PI and the GI scores per se, does not affect oral candidal colonization in healthy dentate subjects.
不良的口腔卫生习惯常被认为是口腔白色念珠菌定植的一个诱发因素，但目前还缺乏令人信服的证据。
评估并比较不同口腔卫生水平（通过菌斑指数和牙龈指数评分确定）的健康有牙颌受试者群体中，口腔白色念珠菌的定殖情况，包括定量和定性两个方面。
采用浓缩口腔冲洗技术从 149 名健康有牙颌受试者中分离白色念珠菌。将白色念珠菌接种于沙氏葡萄糖琼脂平板上，通过芽管试验和全自动 Vitek(R)系统生化酵母卡进行鉴定。根据菌斑指数和牙龈指数评分，将受试者分为不同的口腔卫生水平组。
86 名（57.7%）受试者分离出了白色念珠菌。念珠菌携带率随年龄增长而显著增加（P = 0.023），但男性和女性之间无差异（分别为 58.7%和 56.7%；P = 0.87）。口腔白色念珠菌携带率和密度不受牙齿菌斑或牙龈状况水平的影响。与使用牙线的受试者相比，不使用牙线的受试者口腔白色念珠菌携带率显著更高（P = 0.032）。
单纯通过菌斑指数和牙龈指数评分确定的口腔卫生状况并不影响健康有牙颌受试者的口腔白色念珠菌定植。
