ABSTRACT

Early colonization of periodontal pathogens has been related as a risk indicator for the subsequent development of periodontal disease. Such colonization can be easily detected with mediums like saliva and plaque. This study aimed to evaluate the prevalence of the bacteria associated with periodontal disease in saliva and plaque in healthy children and adolescents. The experiment was conducted using 90 samples from subjects consisting of thirty elementary school students, thirty high school students and thirty adults. PCR was used to detect the prevalence and distribution of five periodontal pathogens in the collected saliva and plaque. The detected periodontal pathogens are as follows: A. actinomycetemcomitans, P. gingivalis, T. forsythia, F. nucleatum and P. intermedia. Periodontal pathogens were prevailed in a higher number of adolescents than the number of children. A. actinomycetemcomitans and P. intermedia were detected the most in the adolescents group. T. forsythia and F. nucleatum were detected the most in the children group. The overall result showed that saliva is more a useful medium than supragingival plaque. The detection of high risk periodontal pathogens in children and adolescents without clinical signs of periodontal disease can emphasize the importance of the early diagnosis and preventive approach.
