OBJECTIVES. To evaluate the microbiological effects of mechanical instrumentation (SM) associated to self-administrated use of local antimicrobials (AmF/SnF 2) in periodontal patients. MATERIALS AND METHODS. Patients underwent single or multiple sessions of SM and were prescribed with AmF/SnF 2-containing toothpaste and mouthrinse for 12 weeks. Subgingival microflora was sampled before SM and 12 weeks after SM. RESULTS. 12-week after SM bacterial counts still exhibited a substantial reduction with respect to those before SM (Total Bacterial Count: - 70%; Total Pathogens: - 69%; Red Complex: - 75%; Aggregatibacter (Actinobacillus) actynomicetemcomitans: - 94%). CONCLUSIONS. SM plus antimicrobial regimen induce a non-selective reduction of subgingival microbial flora, including periodontal pathogens bacteria, which persists after 3 months following treatment.
