Fig. (1) Clinical changes after non-surgical periodontal therapy. All periodontal sites were examined for bleeding on probing (BOP) and probing depth (PD) for patients D114 (a) and D119 (b) after non-surgical periodontal therapy. Both patients received Amoxicillin (500 mg) and Metronidazole (500 mg) TID for 8 days in conjunction with full mouth scaling and root planning completed over 2 visits. The follow up clinical examinations were conducted 8 weeks after the baseline examination. There were reduction of BOP and PD (from ≥6 mm to PD of 4-5 mm) in both patients.
