Abstract
OBJECTIVES: Compare the prevalence of certain periodontal pathogens in cases of aggressive and chronic periodontitis according to the valid classification at the time of the studies, in 101 Uruguayan patients. METHODS: This analysis is based on the works of detection of periodontal pathogens in patients with chronic and aggressive periodontitis in Uruguay using conventional and molecular methods (1,2). Both works analysed the same microorganisms and used the same techniques of recovery and analysis. Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Prevotella intermedia and Fusobacterium nucleatum were studied. RESULTS: A higher prevalence of F. nucleatum, T. forsythia and P. gingivalis was noticed in chronic cases whereas higher detections of F. nucleatum and P. intermedia were observed in aggressive ones. Within the last one, a higher proportion of P. gingivalis and T. forsythia was detected in the generalized and A. actinomycetemcomitans in the localized ones. CONCLUSIONS: It was found that the patterns documented in the bibliography remained in our country (3,4).
