ASSOCIATION OF THE BONE LOSS WITH MAIN CLINICAL AND MICROBIOLOGICAL PARAMETERS IN CHRONIC PERIODONTITIS

Literature data have reported that certain Gramnegative anaerobe bacteria from the subgingival environment are important etiological agents of chronic periodontal disease.Based on published criteria identifying periodontal pathogens, major evidences has been shown for: Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis and Tannerella forsythia; moderate evidences for: Prevotella intermedia, Peptostreptococcus /Micromonas/ micros, Fusobacterium nucleatum, Eubacterium nodatum, Campylobacter rectus, and spirochetes (Treponema denticola).Microbiological data has been suggested by several studies as a useful indicator of disease progression, selection of an adjunctive antimicrobial administration, healing assessment and disease recurrence.The results of this study demonstrate statistically significant correlation between periodontal attachment loss and the prevalence of Porphyromonas gingivalis, Tannerella forsythia and Peptostreptococcus (Micromonas) micros in deep periodontal pockets of severe chronic periodontitis patients.
