NCT01098448

Brief Summary

The purpose of this study is to test combined effects of scaling and root planing with periodontal surgery, systemically administered amoxicillin and metronidazole, and/or local tetracycline on pocket depth reduction and attachment level "gain" in patients with chronic periodontitis.
