Szukana fraza: [Abstrakt = "Chronic periodontitis, along with caries, are considered to be the most frequent pathological processes occurring in the oral cavity. Periodontal pockets, which are formed in the course of these diseases, make a perfect niche for microorganisms, especially anaerobic bacilli, which are characterised by high pathogenicity. It has been proved that bacteria, bacterial products and inflammatory and immunological mediators present in the pathologically changed periodontium may have an influence outside the oral cavity, and the pathogens coming from the periodontium may be an inflammatory factor participating in the aetiopathogenesis of vascular diseases related with atheromatous processes. Although numerous scientists have dealt with the problem of occurrence of bacteria coming from periodontal pockets in the atheromatous plaque collected from coronary vessels, carotid arteries and the walls of abdominal aortic aneurysms, the role of periopathogens in the aetiopathogenesis of vascular diseases has not been thoroughly explained. Therefore, a decision was made to start research on this controversial problem. The aim of this dissertation was to evaluate the condition of the periodontium in patients with atherosclerosis and abdominal aortic aneurysms and to examine the occurrence of 5 selected bacterial pathogens\: Porphyromonas gingivalis, Tanarella forsythiensis, Actinomyces actinomycetemcomitans, Prevotella intermedia and Treponema denticola in the patients\? periodontal pockets. The atheromatous plaque and specimens of the pathologically changed walls of aortic aneurysms were checked for the occurrence of the selected periopathogens."]
