ObjectivesThe primary aim of this study was to investigate the prevalence of peri‐implant diseases in a randomly selected Norwegian population. The secondary aims were to explore risk indicators for peri‐implant diseases and to validate self‐reported outcome measures from a survey with clinical parameters.Material and MethodsPatients (n = 3083) rehabilitated with dental implants in 2014 were mailed a questionnaire and invited to a clinical examination. A randomly selected subset of responders underwent a clinical examination (n = 242). Full mouth clinical and radiographic examinations were conducted. Multiple logistic regression was used to assess patient‐related risk indicators for peri‐implantitis. Self‐reported data were compared with data from the clinical examination using Spearman correlation and binary logistic regression.ResultsThe prevalence of peri‐implantitis was 17.0% at patient level and 8.6% at implant level, according to the 2018 classification. Risk indicators for peri‐implantitis included smoking and periodontitis in the adjusted model. The correlation was strong (r = 0.91, p < 0.001) between number of self‐reported implants and clinical counts, whereas self‐reported peri‐implant inflammation was associated with peri‐implantitis (OR 6.4 [95% CI 3.0, 13.7]).ConclusionsSmoking and periodontitis were identified as key risk indicators for peri‐implantitis. Questionnaire data rendered clinically valid estimates of implant number, and self‐reported peri‐implant inflammation was associated with clinical peri‐implantitis.

挪威随机人群种植体周围疾病的横断面研究：患病率、风险指标和患者报告结果的临床验证


目的本研究的主要目的是调查随机选择的挪威人群中种植体周围疾病的患病率。次要目标是探索种植体周围疾病的风险指标，并验证来自具有临床参数的调查的自我报告的结果测量。材料和方法2014 年使用种植牙康复的患者 （n = 3083） 邮寄了一份问卷并被邀请参加临床检查。随机选择的反应者子集接受了临床检查 （n = 242）。进行全口临床和影像学检查。多元 logistic 回归用于评估种植体周围炎的患者相关风险指标。使用 Spearman 相关和二元 logistic 回归将自我报告的数据与临床检查数据进行比较。结果根据 17.0 年的分类，患者层面种植体周围炎的患病率为 8.6%，种植体水平为 2018%。种植体周围炎的风险指标包括调整模型中的吸烟和牙周炎。自我报告的种植体数量与临床计数之间存在很强的相关性 （r = 0.91，p < 0.001），而自我报告的种植体周围炎症与种植体周围炎相关 （OR 6.4 [95% CI 3.0， 13.7]）。结论吸烟和牙周炎被确定为种植体周围炎的关键危险指标。问卷数据提供了临床上有效的种植体数量估计值，自我报告的种植体周围炎症与临床种植体周围炎相关。
