To assess tooth-related factors contributing to tooth loss over a period of 10 years after completion of active periodontal therapy (APT).
All patients who had received APT by the same experienced periodontist, 10 years before beginning the research, were recruited until 100 patients were re-examined. Examinations included, at the patient level: test for interleukin-1 polymorphism, compliance to supportive periodontal therapy (SPT), mean plaque scores during SPT; at the tooth level: assessment of baseline bone loss (type, amount), tooth type, furcation status and abutment status. Logistic multilevel regression was performed for statistical analysis.
Hundred patients with 2301 teeth at the baseline (completion of APT) were retrospectively examined. One hundred fifty-five teeth were lost over 10 years after APT. Logistic multilevel regression identified high plaque scores, irregular attendance of SPT and age as patient-related factors significantly accounting for tooth loss. Tooth-related factors significantly contributing to tooth loss were baseline bone loss, furcation involvement and use as an abutment tooth. However, in patients with regular SPT, 93% of teeth with 60-80% bone loss at the baseline, survived 10 years.
The following tooth-related risk factors for tooth loss were identified: baseline bone loss, furcation involvement, and use as an abutment tooth.
评估在积极牙周治疗（APT）完成后的10年期间导致牙齿缺失的牙齿相关因素。
招募所有在研究开始前10年由同一位经验丰富的牙周病医生进行过APT治疗的患者，直至重新检查了100名患者。检查包括：在患者层面，白细胞介素-1多态性检测、对支持性牙周治疗（SPT）的依从性、SPT期间的平均菌斑评分；在牙齿层面，基线骨丧失评估（类型、数量）、牙齿类型、根分叉状况和基牙状况。进行逻辑多水平回归分析。
对100名在基线（APT完成时）有2301颗牙齿的患者进行了回顾性检查。在APT后的10年中，有155颗牙齿缺失。逻辑多水平回归分析确定，菌斑评分高、不定期接受SPT和年龄是与患者相关的、显著导致牙齿缺失的因素。显著导致牙齿缺失的牙齿相关因素为基线骨丧失、根分叉病变和作为基牙使用。然而，在定期接受SPT的患者中，基线骨丧失60%-80%的牙齿中有93%存活了10年。
确定了以下与牙齿缺失相关的危险因素：基线骨丧失、根分叉病变和作为基牙使用。
