| 牙周炎是一种由菌斑引起的以牙周软组织和牙槽骨破坏为特征的慢性感染性疾病，其病因尚不明确，目前普遍认为是细菌
感染和宿主防御相互作用的结果，受遗传有关的宿主易感性、环境、行为因素的影响。致病菌的存在是牙周炎发生的必要条件，基

抗原识别有关的物质。FcrR 就是其中之一。FcrR 属于免疫球蛋白超家族，主要有FcrRI、FcrRII、FcrRIII 三类，大量研究表明

| 英文摘要: |
| Human periodontitis is a chronic infectious disease that is characterized by plaque-induced destruction of periodontal
soft tissue and alveolar bone. The etiology of the disease is unclear, but it is commonly believed that bacterial infection interacts with host
defense, which is modified by a multitude of agents, such as genetic, behavioral and environmental factors. Genetic factors can influence
the intensity and severity of host responses to bacterial challenge, which may result in various levels of periodontal tissue destruction.
Most genetic research in periodontitis has focused on gene polymorphisms that play roles in immunoregulation or metabolism, such as
cytokines, cell-surface receptors, chemokines, enzymes and others that are related to antigen recognition, including FcrR. Therefore,
many studies have been carried out to investigate genetic susceptibility to periodontal diseases. The human leukocyte FcrR family consists
of 3 classes: FcrRI, FcrRII, FcrRIII. In many studys, FcrRIIA has been documented to be associated with the susceptibility of periodontitis.
However, the results are various from different race. It also suggests genetic polymorphisms of the allele frequency differences
between races result in differences in the definition of periodontitis etiology and prognosis related applications. Genetic diagnosis will become
the new direction for periodontal disease prevention and treatment in the future. This article mainly reviews the current research
progress of correlation of Fc RIIA polymorphisms with periodontitis. |
