Anaerobic Microbiological study of periodontitis in Salah Al – Deen City

Abstract

Oral flora responsible for periodontal disease is polymorphic. The periodontal infection results either from the penetration of pathogenic microorganisms in the tissues, or even the activation of already existing germs, but not pathogenic under normal conditions. The aims of this study was carried out to evaluate selected bacterial agent s causing periodontitis. One hundred eighty samples were examined in the present study. Clinical measurements of per iodontal parameters used included dental plaque index, gingival index, bleeding on probing, probing pocket depth and clinical attachment loss. The results of periodontitis were the most comm on anaerobic periodontal bacteria isolated from patients were pe ptostreptococcus prevotii which represented 15(8.3%) isolates, while prevotella intermedia, prevotella melani, prevotella disiens, Bifidobacterium sp., Fusibacterium mortiferum peptostreptococcus tet radius, and Wolinella sp. represented only 1 (0.5%) isolates.Also another anaerobic subgingival bacteria isolated from inflamed sites in patients were fusibacterium varium ,vellionella sp., campylobacter gracilis, capnocytophaga sp. ,peptostreptococcus magnus, peptostreptococcus micros, peptostreptococcus niger,peptostreptococcus anaerobius, staphylococcus saccharolyticus, streptococcus consellatus, and gemella morbillorum. Concerning to the results of this study the researcher concludes peptostreptococcus prevotii, prevotella intermedia, prevotella melani, prevotella disiens, Bifidobacterium sp., Fusibacterium mortiferum peptostreptococcus tetradius, and Wolinella sp. fusibacterium varium ,vellionella sp., campylobacter gracilis, capnocytophaga sp. ,peptostreptococcus magnus,eptostreptococcus micros, peptostreptococcus niger,peptostreptococcus anaerobius, staphylococcus saccharolyticus, streptococcus consellatus, and gemella morbillorum were the most common anaerobic periodontal pathogens isolated from patients in the present study.
