Inclusion criteria

Inclusion criteria: - Systematic periodontal treatment not prior to October 2004 consisting of step 1 (supragingival biofilm and risk factor control), step 2 (SI in cases of aggressive or severe chronic periodontitis and detection of Aggregatibacter actinomycetemcomitans with adjunctive systemic antibiotics (Eickholz et al., 2013)) and if required step 3 (surgical treatment). If A. actinomycetemcomitans had been detected, 500 mg amoxicillin and 400 mg metronidazole were prescribed 3 times daily for 7 days. In case of sensitivity to penicillin, 250 mg ciprofloxacin and 500 mg metronidazole were prescribed 2 times daily for 7 days (Griffiths et al., 2011, Feres et al., 2012). - At least one tooth with class III prior to start of treatment - Complete periodontal charting with probing pocket depth (PPD) and vertical clinical attachment level (CAL-V) at 6 sites/tooth, FI (Hamp et al., 1975) at all furcation entrances of multi-rooted teeth prior to treatment (baseline, T0) and after accomplishment of APT (re-evaluation 1 or 2 and start of SPC, T1). FI was exclusively assessed clinically using a Nabers probe (PQ2N, Hu-Friedy, Chicago, USA). - Radiographs of all teeth at T0 - Follow-up =5 years after accomplishment of APT (complete periodontal charting =5 years after accomplishment of APT, T2) - Supportive periodontal care (SPC) was carried out at the Department of Periodontology of Goethe-University
