| Research Abstract |
In this study, oral microflora was examined in relationship to periodontitis and malodor, and was further analyzed with febrile days and pneumonia in institutionalized elderly. To characterize the composition of oral microflora, chromosomal DNA was extracted from bacteria in saliva or tongue coat and Terminal-Restriction Fragment Length Polymorphism analysis was carried out using the extracted bacterial DNA as template. The results indicated that T-RFLP pattern of salivary bacteria was closely associated with the prevalence of periodontitis and malodor. In addition, T-RFLP pattern in tongue coat was also associated with febrile days and pneumonia in institutionalized elderly.
