Distribution of salivary Lactobacillus and Bifidobacterium species in periodontal health and disease

We surveyed the distribution of salivary Lactobacillus and Bifidobacterium species in periodontitis patients and healthy subjects. Approximately 700 lactobacilli and 300 bifidobacterial isolates were obtained from 16 young, orally healthy subjects (mean age +- standard deviation: 21.0 +- 2.0y), 16 p...

Description
Summary:We surveyed the distribution of salivary Lactobacillus and Bifidobacterium species in periodontitis patients and healthy subjects. Approximately 700 lactobacilli and 300 bifidobacterial isolates were obtained from 16 young, orally healthy subjects (mean age +- standard deviation: 21.0 +- 2.0y), 16 periodontitis patients (51.6 +- 13.8y), and 14 well-maintained former periodontitis patients (60.2 +- 9.6y). Among eleven Lactobacillus species detected in saliva, L. salivarius, L. gasseri, and L. fermentum were prevalent, but no species was specifically associated with periodontal health. In contrast, of four Bifidobacterium species, B. adolescentis was specifically (P0.05) prevalent in young healthy subjects compared with the other two groups. Furthermore, the bifidobacterial count of the well-maintained subjects was the highest (P0.05) among the groups. These results suggest that bifidobacterial count and species might be associated with periodontal health status and/or age.
