Abstract：
OBJECTIVE: To assess the importance of achieving a successfully treated stable periodontitis patient status (PPS) during long-term supportive periodontal care (SPC).
METHODS: This retrospective cohort study included 100 periodontitis patients, who continued for ≥ 7.5 years after active periodontal treatment with SPC and were judged as overall adherent. The effect of various predictors on 3 patient-related outcome parameters was assessed: number of 1) diseased teeth at last SPC, 2) teeth lost due to periodontitis, and 3) teeth lost due to any reason.
RESULTS: One fifth of the patients were classified as stable after active periodontal treatment. After a mean follow-up of 10.77 years, 24 patients lost 38 teeth due to periodontitis. An unstable PPS and a higher number of diseased teeth per patient at first SPC, and inadequate oral hygiene levels over time significantly increased the risk for a higher number of diseased teeth per patient at last SPC and for more lost teeth due to periodontitis. However, high adherence to SPC appeared to mitigate the negative effect of an unstable PPS, especially regarding tooth loss due to periodontitis. Further, tooth loss due to any reason was about 3-times higher than tooth loss due to periodontitis and was affected by a larger number of predictors.
CONCLUSIONS: Successfully treated patients with a stable PPS maintained a low number of diseased teeth and barely lost teeth during long-term SPC compared to patients not achieving a stable PPS after active periodontal therapy. This article is protected by copyright. All rights reserved.

摘要：
目的：评估在长期支持牙周护理（SPC）中成功获得稳定牙周炎患者状态（PPS）的重要性。
方法：这项回顾性队列研究包括100例牙周炎患者，在使用SPC进行主动牙周治疗后持续≥7.5年，并被判定为整体粘附。评估了各种预测因子对3种患者相关结果参数的影响：最后SPC时1）患病牙齿的数量，2）由于牙周炎而失去的牙齿，和3）由于任何原因而丢失的牙齿。
结果：1/5的患者在积极的牙周治疗后被认为是稳定的。经过10.77年的平均随访，24例患者因牙周炎而失去38颗牙齿。在第一次SPC时，不稳定的PPS和每位患者的患病牙齿数量较高，随着时间的推移，口腔卫生水平不足会显著增加每位患者在最后一次SPC时患病牙齿数量增加以及牙周炎导致牙齿丢失更多的风险。然而,对SPC的高依从性似乎减轻了不稳定PPS的负面影响，尤其是牙周炎引起的牙齿脱落。Further,由于任何原因导致的牙齿损失比牙周炎导致的牙齿损失高约3倍，并且受到更多预测因素的影响。
结论：与主动牙周治疗后未达到稳定PPS的患者相比，成功治疗稳定PPS的患者在长期SPC期间保持了较低的患病牙齿数量，并且几乎没有牙齿脱落。本文受版权保护。保留所有权利。
