Background: The aim of this study was to test the hypothesis that there are no differences in clinical parameters in generalized aggressive periodontitis patients after full‐mouth scaling and root planing (FRP) or quadrant‐wise basic periodontal therapy (BPT) when combined with an antibiotic regimen. Methods: Patients were allocated randomly to BPT (N = 15; mean age: 29.5 ± 5.7 years) or FRP (N = 15; mean age: 28.4 ± 5.7 years). All subjects received oral hygiene instructions including the use of a 0.12% chlorhexidine mouthrinse solution twice a day for 2 months. Patients also received amoxicillin, 500 mg, and metronidazole, 250 mg, three times a day for 7 days. Probing depth (PD), clinical attachment level, visible plaque, and bleeding on probing were recorded at baseline and at 2, 4, and 6 months post‐therapy. Statistically significant changes within and between groups were determined using the general linear model repeated measures procedure. Results: Both groups showed a significant improvement in all clinical parameters post‐therapy, which was particularly evident at 2 months in the sites that had been deepest at baseline. For instance, the mean PD at sites with mean PD ≥7 mm at baseline had decreased 3.9 mm in the BPT group and 3.6 mm in the FRP group. At 6 months, the percentage of sites with PD ≥7 mm decreased from 13.2% ± 3.2% to 0% in the BPT group and from 13.3% ± 3.5% to 0.2% ± 0.1% in the FRP group. No statistically significant differences were observed between groups for most clinical parameters. Conclusion: Within the limits of the present investigation, FRP and BPT caused comparable clinical effects in aggressive periodontitis patients when an adjunctive combined antibiotic regimen was included.
