虽然以前的流行病学研究大多集中在牙周破坏的受试者水平的危险因素上，但与牙齿相关的因素还没有得到充分的探索。本研究的目的是使用两水平多水平模型来评估影响牙周病进展的牙齿相关因素和受试者相关因素。材料与方法对286名70岁的社区老年人进行了为期10年的纵向调查。临床附着水平(CAL)被测量在所有存在的牙齿上每颗牙齿的6个部位，牙周疾病进展被定义为CAL=3 mm。结果79%的受试者有牙周疾病进展，最常见的是上颌磨牙。多水平Logistic回归分析显示，戴可摘义齿的受试者患牙周病进展的风险显著。可拆卸/固定义齿的基牙也明显更容易发生牙周破裂。此外，与牙齿相关的变量可能是牙周病进展的危险因素：上颌牙和多根牙。结论固定义齿的多根牙和基牙可能是牙周病进展的危险因素。
P>ObjectiveWhile most previous epidemiological studies have focused on subject-level risk factors for periodontal destruction, tooth-related factors have not been fully explored. The purpose of this study was to evaluate both tooth-related and subject-related factors affecting periodontal disease progression using a two-level multilevel model.Material and MethodsA longitudinal survey over a period of 10 years was carried out on 286 community-dwelling elderly subjects aged 70 years at baseline. Clinical attachment level (CAL) was measured at six sites per tooth on all teeth present and periodontal disease progression was defined as CAL >= 3 mm.ResultsPeriodontal disease progression was found in 79% of the subjects and most frequently in maxillary molars. Multilevel logistic regressions revealed that subjects wearing removable dentures were significantly at risk for periodontal disease progression. Abutment teeth for removable/fixed dentures were also significantly more likely to suffer periodontal breakdown. Furthermore, the following tooth-related variables were found to be possible risk factors for periodontal disease progression: maxillary and multirooted teeth.ConclusionMultirooted teeth and abutments for a fixed denture were possible risk factors for periodontal disease progression.
