In pathology, oral greenery answerable for periodontal illness is polymorphic. The periodontal contamination results either from the infiltration of pathogenic microorganisms in the tissues, or even the actuation of previously existing microbes, yet not pathogenic under ordinary conditions. In excess of Twenty microbes had been confined and recognized from subgengival plaques of patients impacted with forceful (28%) and persistent periodontitis (18,4%),. By and large ,the bacterial greenery of forceful periodontitis had shown prevailing gram-negative and motile morphotypes, among them, straight poles, bended, spirochetes and fusiform Gram negative. For persistent periodontitis the bacterial vegetation is described by the predominance of poles and motile to the uncommon gram-negative morphotypes. Certain microbes known as parodontopathogènes were distinguished in forceful periodontitis as Aggregatibacterium actinomycetemcomitans (7,3%), Prevotella intermedia (4,2%), Eikenella corrodens (6,3%), Bacteroides fragilis (4,6%) and Capnocytophaga sp (4,7%).
Relevance of the topic: the use of antibiotics after surgery in the treatment of periodontal disease is aimed at eliminating the pathogenic microflora of the periodontium, oral cavity and restoring the normal microbiota, which is inherent in healthy periodontal tissues. We know that periodontal diseases are caused by periodontal pathogens: Porphyromonas gingivalis. Actinobacillus actinomycetemcommitans ,Bacteroides forsithus, Threponema denticola , Prevotella intermedia, Actinomices viscosus. Numerous studies suggest that the role of polymicrobial synergy in the development of dental diseases. When prescribing antibacterial drugs, the doctor should remember that most microorganisms of the oral cavity are combined into a microbial biofilm. Microorganisms of the oral cavity form a microbial biofilm on the surface of the teeth – a special form of organization of microorganisms, which is surrounded by a protective matrix – a complex of glycosaminoglycans and proteins. It is this protective matrix that does not allow antibacterial drugs from saliva or gingival fluid to penetrate inside the biofilm. Therefore, microorganisms in the biofilm are more resistant to antibiotics, antimicrobials and other active agents. The most effective choice for the treatment of infectious and inflammatory processes of the oral cavity should be based on the results of modern scientific research, proving the clinical and microbiological efficacy and safety of any drugs.
