目的：本回顾性研究的目的是评估在巴西一家私人牙周诊所接受牙周治疗和支持性牙周治疗（SPT）的患者样本中牙齿脱落的原因。材料和方法：从参加牙周治疗的患者中选择120名治疗并维持10年或更长时间的受试者作为样本。所有患者都接受了类似的治疗：基本程序，重新评估和牙周手术。牙齿脱落的原因分为牙周、龋齿、牙髓、牙根骨折和拔出保留或部分出牙的第三磨牙。结果：在完成积极牙周治疗的2927颗牙中，因牙周病丢失53颗（1.8%），因牙根断裂丢失16颗（0.5%），因龋齿丢失6颗（0.2%），因根管原因丢失5颗（0.2%），因拔出保留或部分出牙的第三磨牙丢失31颗（1.0%）。采用Logistic回归分析研究牙周炎导致的牙齿脱落与5个独立变量之间的关系。只有年龄（0 ~ 60岁）和吸烟有统计学意义（p < 0.05）。结论：本调查结果与以往的研究结果一致。年龄较大的受试者和吸烟者更容易患牙周牙齿脱落。此外，广泛性慢性牙周炎患者接受治疗并长期维持，牙齿脱落率低。
Aim: The objective of this retrospective study was to assess the reasons for tooth loss in a sample of patients who underwent periodontal therapy and supportive periodontal therapy (SPT) in a Brazilian private periodontal practice.Material and Methods: A sample of 120 subjects who had been treated and maintained for 10 years or longer was selected from patients attending a periodontal practice. All patients followed a similar treatment: basic procedures, re-evaluation and periodontal surgery where indicated. Reasons for tooth loss were categorized as periodontal, caries, endodontal, root fractures and extraction of retained or partially erupted third molars.Results: Of the 2927 teeth present at the completion of active periodontal treatment, 53 (1.8%) were lost due to periodontal disease, 16 (0.5%) for root fracture, six (0.2%) to caries, five (0.2%) for endodontic reasons and 31 (1.0%) were lost to extraction of retained or partially erupted third molars. Logistic regression analysis was performed to investigate the association between five independent variables with tooth loss due to periodontitis. Only age (> 60 years) and smoking were statistically significant (p < 0.05).Conclusion: The findings of this survey were consistent with previous studies. Older subjects and smokers were more susceptible to periodontal tooth loss. In addition, patients with generalized chronic periodontitis were treated and maintained for long-term periods with low rates of tooth loss.
