本研究旨在探讨老年人缺牙数与口腔环境因素（刺激唾液流速、缓冲能力、变形链球菌、乳酸菌和念珠菌计数）的关系。研究对象为64名老年固定义齿患者和49名65岁以上的可摘局部义齿患者。我们采用单因素方差分析检验5个口腔环境因素间MT数量的总体差异。使用活动义齿时，乳酸菌数量随活动义齿数量的增加而增加，乳酸菌数量随活动义齿数量的增加而增加。综上所述，对于佩戴活动义齿的患者，MT数量的增加与唾液中乳酸杆菌计数的增加有关。对于戴牙冠和固定义齿的患者，MT数量不受唾液变形链球菌、乳酸菌和念珠菌计数的显著影响。
The purpose of this study was to investigate the relationship between the number of missing teeth (MT) and the statuses of oral environmental factors (the stimulated salivary flow rate, buffering capacity, and the counts of mutans streptococci, lactobacilli, and Candida) in the elderly. The subjects were 64 elderly subjects with fixed prostheses and 49 who wore removable partial dentures aged over 65 years. We used one-way ANOVA to test for overall differences of the number of MT among 5 oral environmental factors. The significant differences were observed in the lactobacilli counts for different number of MT. The number of MT increased with an increase in the lactobacilli counts with removable denture. In conclusion, for the patients wearing removable dentures, increasing number of MT was associated with an increase in the lactobacilli counts in saliva. For the patients with crowns and fixed partial dentures, the number of MT was not significantly affected by salivary mutans streptococci, lactobacilli, and Candida counts.
