    Author: Aimetti M, Romano F, Guzzi N, Carnevale G.
    Journal: J Clin Periodontol; 2012 Mar; 39(3):284-94. PubMed ID: 22220822.
    Abstract:
    AIM: The present investigation aimed to analyse clinical and microbiological effects of systemic administration of metronidazole and amoxicillin combined with the One-Stage-Full-Mouth-Disinfection protocol (OSFMD) in generalized aggressive periodontitis patients (G-AgP). MATERIALS AND METHODS: Thirty-nine systemically healthy patients with G-AgP were consecutively included. The test group (n = 19) received amoxicillin-metronidazole combination (500 mg of each, three times a day for 7 days) and the OSFMD, the control group (n = 20) received the OSFMD and a placebo. In addition to clinical parameters subgingival plaque samples from moderate (4-5 mm) and deep (≥ 6 mm) pocket sites were analysed for the presence of Aggregatibacter actinomycetemcomitans, Prevotella intermedia, Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola using polymerase chain reaction. RESULTS: Both therapies led to a statistically significant decrease in clinical and microbiological parameters compared to baseline (p < 0.001). The most beneficial changes were observed in the test group which showed significantly greater improvements in probing depth and clinical attachment level and a lower prevalence of Aggregatibacter actinomycetemcomitans, Treponema denticola, and Tannerella forsythia compared to the control one (p < 0.05). CONCLUSIONS: Systemic administration of metronidazole and amoxicillin as an adjunct to OSFMD therapy significantly improved clinical and microbiological outcomes in patients with G-AgP over a 6-month period.
