目的：本研究旨在探讨积极牙周治疗(APT)后残余PPD和探诊出血(BOP)对牙周炎和牙齿脱落的影响。材料和方法：本研究回顾队列中172例接受APT和支持性牙周治疗(SPT)3-27年(平均11.3年)的患者。分析是利用现场、牙齿和患者水平的信息进行的。采用多水平Logistic回归分析，探讨危险因素与牙周炎牙体脱落和牙周炎进展的关系。结果：在SPT过程中，残留PPD数量增加。PPD分别为7mm37.9和64.2。在患者水平上，重度吸烟、初诊、SPT和PPD>；=6 mm是疾病进展的危险因素，而PPD>；=6 rum和BOP>；=30%代表牙齿脱落的风险。结论：残留PPD>；=6 mm代表牙周治疗结果不完整，需要进一步治疗。
Background: Limited evidence exists on the significance of residual probing pocket depth (PPD) as a predictive parameter for periodontal disease progression and tooth loss.Aim: The aim of this study was to investigate the influence of residual PPD >=, 5 mm and bleeding on probing (BOP) after active periodontal therapy (APT) on the progression of periodontitis and tooth loss.Material and Methods: In this retrospective cohort, 172 patients were examined after APT and supportive periodontal therapy (SPT) for 3-27 years (mean 11.3 years). Analyses were conducted using information at site, tooth and patient levels. The association of risk factors with tooth loss and progression of periodontitis was investigated using multilevel logistic regression analysis.Results: The number of residual PPD increased during SPT. Compared with PPD = 7 mm 37.9 and 64.2, respectively. At patient level, heavy smoking, initial diagnosis, duration of SPT and PPD >=, 6 mm were risk factors for disease progression, while PPD >= 6 rum and BOP >= 30% represented a risk for tooth loss.Conclusion: Residual PPD >= 6 mm represent an incomplete periodontal treatment outcome and require further therapy.
