| Research Abstract |
A comparison of national surveys on oral health suggested that the population of South Korea has better periodontal health status than that of Japan, despite their similar inherent background. Here, we investigated differences in oral bacterial assemblages between Korean and Japanese orally healthy adults. The microbiota of Japanese subjects comprised a more diverse community, with higher proportions of 17 bacterial genera, including Veillonella, Fusobacterium and Prevotella, as compared with those of Korean subjects. Conversely, Neisseria and Haemophilus species were present in much lower proportions in the microbiota of Japanese subjects. Because higher proportions of Prevotella and Veillonella and a lower proportion of Neisseria were implicated in periodontitis in our previous study, the results of this study suggest that the greater proportion of dysbiotic oral microbiota in the Japanese subjects is related to their higher susceptibility to periodontitis.
