Abstract
Objectives: The purpose of this study was to evaluate the association between the distribution of periodontopathic bacteria and oral conditions.
Methods: Stimulated saliva was collected from 162 adults aged 60 years and above. The prevalence and amount of periodontopathic bacteria in the saliva were analyzed using real-time PCR. Pocket depth and clinical attachment loss were examined to evaluate the oral conditions of the subjects. Patients who had at least one tooth surface involved, with a pocket depth ≥4 mm or clinical attachment loss ≥5 mm were classified as having periodontal disease.
Results: The detection rates of most bacteria in the orange and green complexes were more than 90%, while those of P. gingivalis and T. forsythia in the red complex were 58.6% and 61.7%, respectively. The number of bacteria in the red complex positively correlated with each other. There were no significant differences in the number of types of red complex bacteria in the saliva and the distribution of residual number of teeth and periodontal disease (P>0.05). On the other hand, the number of remaining teeth in subjects with higher bacterial density were more than those with lesser bacterial density. In addition, the occurrence of dental disease differed significantly depending on the number of P. gingivalis and T. forsythia.
Conclusions: The relative amount of periodontopathic bacteria is important in the occurrence of periodontal disease, and the number of these bacteria positively correlated with each other.
