Sumario:Objetive: Evaluate microbiological composition and clinical features of periodontal pockets at initial phase, after initial therapy, and during third and sixth month, in response to surgical and non surgical periodontal treatment. Materials and Techniques: Patients with chronic periodontitis diagnosis were split in two groups: treated with mechanical therapy alone, and those who besides mechanical therapy underwent on surgical intervention. Clinical records were taken (Bacterial plaque, bleeding probing, pocket depth, clinical attachment level and recession). Subgingival biofilm samples were obtained from 22 sites in 4 differents phases. Polymerase chain reaction technique identified putative periopathogens (Porphyromona gingivalis, Treponema denticola, Tanerella forsythia). Patients were reassessed at thirth and sixth month after treatment. Results: improvement in clinical features and percentage of infected sites were found after initial therapy, especially during maintenance months. T denticola was prevalent specie (59%) and bacterial asociation between T. denticola and P. gingivalis were found in 14% of samples. Conclutions: both treatments significantly improved clinical features and reduce infected periodontal pockets. However the clinical advantage of surgery , wasn´t conclusive in periodontal lessions without bone regeneration. Obtained benefits appeared mostly in maintenance therapy.
