      abstract     = {To assess the impact of active (APT) and supportive
                      periodontal therapy (SPT) on the change in probing depth
                      (PD) and annual tooth loss in partially and fully compliant
                      and drop-out patients.Data of 280 periodontally treated
                      partially and fully compliant (regular supportive visits,
                      SPT duration 5.5 ± 4.5 years) and 55 drop-out patients (SPT
                      and drop-out duration 8.3 ± 3.8 years, only drop-out
                      duration 5.3 ± 3.7 years) were recorded. PD data and the
                      number of teeth present at the start of APT (T1) and at the
                      start of SPT (T2) were taken from the patient files and
                      evaluated at the time of the final examination (T3).Annual
                      tooth loss during SPT was significantly higher (p < 0.001)
                      in drop-out patients than in partially and fully compliant
                      patients (0.31 ± 0.50 vs. 0.19 ± 0.55, respectively). In
                      partially and fully compliant and drop-out patients, the
                      mean PD (all available site data) decreased significantly
                      between T1 (3.61 ± 0.82 vs. 3.70 ± 0.73 mm) and T2 (2.68
                      ± 0.40 vs. 2.76 ± 0.42 mm), while the values increased
                      again slightly up to T3 (2.74 ± 0.41 vs. 2.99 ± 0.75
                      mm).In partially and fully compliant patients, SPT had a
                      positive impact on PD stability and medium-term tooth
                      preservation. In contrary to expectations, drop-out
                      patients, PD did not return to baseline values, although PD
                      stability was not achieved.},
