ABSTRACT
Objectives@#Periodontitis-causing microorganisms and their virulence factors can provoke periodontal destruction in the host. This study was aimed at evaluating the distribution of periodontal disease and its relationship with 11 periodontal disease-causing bacteria in the elderly. @*Methods@#Individuals aged 60 years or above were recruited after obtaining informed consent. The clinical attachment loss was measured at studied sites to determine the severity of periodontitis. Further, the stimulated salivary samples were collected and analyzed with real-time polymerase chain reaction to detect 11 strains of periodontitis-causing bacteria. @*Results@#The severity of periodontal disease was proportional to the amount of periodontal diseasecausing bacteria. Porphyromonas gingivalis in the red complex increased from 6.60±5.50 in stage 1 to 5.36±5.39 in stage 2 and 7.19±5.56 in stage 3 (P=0.003). Tannerella forsythia increased from 6.54±4.60 in stage 1 to 7.44±4.56 in stage 2 and 8.49±4.70 in stage 3 (P=0.007). @*Conclusions@#The presence of complex bacterial groups and their number of strains were high in participants with severe periodontitis. Controlling periodontitis-related bacteria is important for periodontal health in the elderly.
