Outline of Final Research Achievements

Periodontal disease not only causes the loss of teeth but is also associated with systemic diseases, such as circulatory disease and diabetes. Three bacterial species, P. gingivalis, T. forsythia, and T. denticola, known as the red complex, are the major causative agents of periodontitis and are highly associated with its severity. In this study, the periodontal pathogens were detected in the plaque samples from 48 female university students, 22 mothers who now raising their infants, and 33 elderly women, by using the species-specific polymerase chain reaction method. The detection rates of the above 3 species in the university students were lowest of the three groups. The results suggested importance of the oral care for women before reaching pregnancy. Furthermore, the composition of oral bacterial flora from university students was most diverse out of these three groups.
