The occurence of periodontal pathogens in subgingival flora in periodontitis is a risk for periodontal disease progression. Therefore microbiologic diagnostic procedures are justifiably indicated in the detection of pathogens, monitoring of therapy success and outcome of the disease. The aim of this study was to show the effect of scaling and root planing on clinical and microbiological factors in 28 patients with chronic and aggressive periodontitis. Clinical assessment and microbiological testing were performed prior to, and three months after mechanical therapy. The presence or absence of bacterial plaque, gingival bleeding, pocket depth and attachment loss were assessed before and three months after scaling and root planing. Samples of subgingival plaque taken from periodontal pockets, were analysed by polymerase chain reaction technique for the presence of seven bacterial pathogens.
Results of clinical parameters and bacterial prevalence were analysed before and after therapy by Wilcoxon Rank test.
The mean pocket depth significantly decreased from 3.9 to 3.0 mm. Clinical attachment level decreased moderately from 4.1 to 3.8 mm. Mean plaque and gingival bleeding values also decreased after therapy. The prevalence of subgingival pathogens in relation to subjects was as follows: only one pathogenic species was found in 28.6%, two were found in 46.4% and three in 14.3% of subjects. The most prevalent pathogens were bacteroides forsythus in 85.7%, Porphyromonas gingivalis in 32.1%, Actinobacillus actinomycetemcomitans and Fusobacterium in 32.1% of subjects. After therapy the prevalence of pathogens decreased moderately. The total number of tested pathogens decreased in 12 subjects and this result was statistically significant. (p=0.001). In 16 subjects the number of pathogens was the same, and did not increase in any of the subjects. The results indicate that the effect of scaling and root planing in the treatment of periodontitis was effective in achieving clinical and microbiological improvement by decreasing the prevalence of pathogens responsible for disease progression.
