Periodontitis is a common disease that is considered to be a manifestation of the distortion of the ratio between the normal and conditionally pathogenic microflora of periodontal pockets. In this study, the ratio between the six most important periodontal pathogens and the total microflora of the periodontal pocket in healthy individuals and patients with varying severity of periodontitis was ...

BACKGROUND Periodontitis is a disease that affects and destroys the tissues that support teeth. Tissue damage results from a prolonged inflammatory response to an ecological shift in the composition of subgingival biofilms. Three bacterial species that constitute the red complex group, Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola, are considered the main pathogens inv...

Prosthodontic treatment using dental implants is one of the solutions for partially and completely edentulous patients. The peri-implant area is colonized by a large variety of oral microbial complexes. Various prosthesis may provide means of mechanical attachment to the microflora; this in turn allows their aggregation and colonization. There exists a relationship between the peri-implant micr...

Aim of the study. To determine the role of bacteria on the dorsal surface of the tongue in periodontal disease. Material and methods. Fifthytwo patients aged 18 to 25 were enrolled in the study; the subjects had to complete a questionnaire on general health, diet and dental hygiene habits. Decay-missingfilled teeth index (DMFT), the periodontal screening index (PSI), bleeding on probing (BOP) a...

Advances in molecular research and the oral microbiome [3] study have depicted the number of oral bacteria (cultivable and not) to a mind-boggling 700 species! The subgingival biofilm is the primary etiology of periodontal disease initiation and progression and for this reason periodontal microbiology has been the focus of research over centuries. It has gone through paradigm shifts of ideologi...

BACKGROUND To assess changes in oral microflora in dental plaque from cancer patients within 7 days of the first course of chemotherapy, and the relationship of the changes with mucositis. MATERIAL AND METHODS Thirty cancer patients, divided into a test group undergoing chemotherapy and a control group no undergoing chemotherapy, were enrolled in this pilot study. Oral microflora were culture...

processes of periodontal disease. Long term sensitization with oral microflora may cause tissue destruction by an intricate mechanism. In this report, the chronic sensitization with human oral bacteria in guinea pigs was analyzed and the antibody to oral bacteria was assayed. The presense of antibody to oral bacteria or to the patient's own gingiva extract in sera of subjects with periodontal d...

In the present work, metronidazole and doxycycline with different antibacterial spectra are proposed to be formulated as combination therapy to have a broader antibacterial therapy, which is effective against both aerobic and anaerobic periodontal microflora. Simultaneous use of metronidazole and doxycycline is effective against wide range of periodontal pathogens. Metronidazole and doxycycline...

Recently developed molecular methods have made it possible to characterize mixed microflora in their entirety, including the substantial numbers of bacteria which do not grow on artificial culture media. In a previous study, molecular analysis of the microflora associated with acute oral infections resulted in the identification of three phylotypes, PUS3.42, PUS9.170, and PUS9.180, representing...
