To evaluate the survival of teeth with class II furcation involvement (FI) ≥ 5 years after active periodontal treatment (APT) and to identify the prognostic factors.
All charts of patients having undergone APT at the Department of Periodontology of Goethe-University Frankfurt, Germany, were screened for teeth with class II FI. APT had to be accomplished ≥ 5 years ago. Charts were analysed for data of class II FI teeth at baseline (T0), after APT (T1) and at the last supportive periodontal care (SPC/T2).
Two-hundred and twenty-two patients (age: 56.5 ± 10.1 years; 118 females; 35 active smokers; 17 diabetics, 154 stage III, 68 stage IV, 94 grade B, 128 grade C) presented 543 teeth with class II FI. Sixty-one patients lost 93 teeth (17%), on average, over 108.4 ± 36.5 months of SPC. Logistic/Cox proportional hazards mixed-model regressions associated increased tooth loss with irregular SPC (p = 0.023/0.073), premolar versus molar (p = 0.041/0.017), root canal filling (RCF) (p < 0.001) and multiple class II FI per tooth at T1 (p = 0.001/0.024).
Of a total of 543 teeth with class II FI, 83% were retained for 108.6 ± 36.5 months. Multiple class II FI at T1, RCF, premolars and irregular SPC were found to compromise the long-term prognosis of teeth with class II FI.
评估II度根分叉病变（FI）牙齿在积极牙周治疗（APT）后≥5年的存留情况，并确定预后因素。
对德国法兰克福歌德大学牙周病科接受过APT治疗的所有患者病历进行筛查，以寻找患有II度FI的牙齿。APT必须在≥5年前完成。分析病历中II度FI牙齿在基线（T0）、APT后（T1）以及最后一次支持性牙周治疗（SPC/T2）时的数据。
222例患者（年龄：56.5±10.1岁；女性118例；35例现吸烟者；17例糖尿病患者，154例III期，68例IV期，94例B级，128例C级）共有543颗II度FI牙齿。在平均108.4±36.5个月的SPC期间，61例患者失去了93颗牙齿（17%）。逻辑/考克斯比例风险混合模型回归分析显示，牙齿脱落增加与不规律的SPC（p=0.023/0.073）、前磨牙与磨牙（p=0.041/0.017）、根管充填（RCF）（p<0.001）以及T1时每颗牙齿多个II度FI（p=0.001/0.024）有关。
在总共543颗II度FI牙齿中，83%存留了108.6±36.5个月。发现T1时多个II度FI、RCF、前磨牙以及不规律的SPC会影响II度FI牙齿的长期预后。
