摘要

Abstract Background . Periodontitis has a complex etiology, with bacteria constituting the main etiological factor. It is not a classic infectious disease, because it is not caused by a specific pathogen. Instead, it is caused by a shift in the microbiological composition, so that the microorganisms, which physiologically inhabit the oral cavity, become pathogenic. Objectives . The aim of this study is to discuss whether the presence of specific bacteria depends on the form of the disease or on the depth of the periodontal pocket. Material and Methods . The study included 60 patients with chronic or aggressive periodontitis. Periodontal parameters were evaluated and the microbiological material from periodontal pockets was collected. Results . Porphyromonas gingivalis occurred more frequently in patients with chronic periodontitis, Aggregatibacter actinomycetemcomitans was observed only in patients with aggressive periodontitis. The occurrence of Treponema denticola and Aggregatibacter actinomycetemcomitans differed depending on the pocket depth. Conclusion . The bacterial spectrum and count is not directly related to the pocket depth, so it is not only an effect of the disease progression. Although some relations between bacterial species and particular forms of periodontitis have been observed, they cannot constitute the basis of the diagnosis and differentiation between chronic and aggressive periodontitis. Microbiological testing of the subgingival biofilm would gain more value if extended to studies related to antibodies to selected bacteria.
