Abstract | BACKGROUND: METHODS: Fifteen individuals with aggressive periodontitis received non-surgical periodontal treatment and 45 days after completion of treatment were treated with antibiotics. Clinical data and samples of subgingival plaque were collected at baseline, 45 days after the non-surgical periodontal treatment, and 1 month after the use of antimicrobial agents. After 3 and 6 months, only clinical data were collected. The presence and quantification of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), Treponema denticola (Td), and Dialister pneumosintes were determined by real-time polymerase chain reaction. RESULTS: All clinical parameters, with the exception of clinical attachment level (CAL), had significantly (P <0.05) improved at the end of the third month after non-surgical therapy associated with antibiotics. There was significant (P <0.05) reduction in the quantities of Td and Tf. After 1 month, there were significant (P <0.05) reductions in the frequencies of Pg and Tf. CONCLUSION: Non-surgical mechanical treatment associated with the use of amoxicillin and metronidazole led to an improvement in all clinical parameters studied, except for CAL, and significantly reduced the amount of subgingival Tf and Td.
