Abstract |
The detection of special bacteria of oral plaque and quantitative analysis are possible through the real-time PCR technique. The aim of this study was to investigate the prevalence and the amount of five periodontopathic bacteria using real-time PCR, and evaluate the relationship among amount of bacteria, plaque index and gingival index. Sixty five subjects ranging from 8 to 18 years old were enrolled. Plaque index and gingival index were examined and five periodontopathic bacteria were surveyed in subgingival plaque samples. The results were analyzed by ANOVA and Pearson's correlation. Results: The prevalence of P. gingivalis was 61.5%, T. forsythia was 53.8%, T. denticola was 29.2%, A. actinomycetemcomitans was 15.4% and F. nucleatum was 100%. Plaque index and gingival index have a significant relationship with the amount of F. nucleatum. The amount of T. forsythia has a strong relationship with the amount of T. denticola and A. actinomycetemcomitans(p<0.05). |
