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.
评估积极牙周治疗（APT）和支持性牙周治疗（SPT）对部分和完全依从患者以及退出治疗患者的探诊深度（PD）变化和年度牙齿缺失的影响。
记录了280例接受牙周治疗的部分和完全依从患者（定期进行支持性复诊，SPT持续时间为5.5±4.5年）以及55例退出治疗患者（SPT和退出治疗持续时间为8.3±3.8年，仅退出治疗持续时间为5.3±3.7年）的数据。PD数据以及APT开始时（T1）和SPT开始时（T2）的牙齿数量取自患者档案，并在最终检查时（T3）进行评估。
退出治疗患者在SPT期间的年度牙齿缺失显著高于部分和完全依从患者（p<0.001）（分别为0.31±0.50和0.19±0.55）。在部分和完全依从以及退出治疗的患者中，平均PD（所有可用部位数据）在T1（3.61±0.82对3.70±0.73mm）和T2（2.68±0.40对2.76±0.42mm）之间显著降低，而到T3时又略有增加（2.74±0.41对2.99±0.75mm）。
在部分和完全依从的患者中，SPT对PD稳定性和中期牙齿保留有积极影响。与预期相反，退出治疗的患者，尽管未实现PD稳定性，但PD并未恢复到基线值。
