第93届国际牙科研究协会会议展览(IADR)即将召开,美国波士顿马萨诸塞州综合医院研究员Sheila Arvikar,将在此会议中提出一项名为“口腔炎症与风湿性关节炎”的议题。
牙周炎与类风湿性关节炎(RA)的致病机制可能相同。在这项研究中,研究人员通过牙科联合检查确定了卟啉单胞菌属龈拟杆菌(p . gingivalis)抗体,并分析了早期炎症微环境和慢性风湿性关节炎之间的情况。
这项研究中有23名慢性风湿性关节炎患者(15例新发疾病,8例慢性病例),与20名年龄或性别相符的健康受试者(HS)共同参与本研究,健康受试者没有牙周炎或者慢性风湿性关节炎。通过ELISA实验测定卟啉单胞菌属龈拟杆菌IgG抗体血清。通过Luminex液相技术进行测量血清、唾液、牙龈缝液(GCF)和关节液中的二十种炎性介质。
研究中23例病人(87%女性)中除了一例之外都接受了常规的牙科治疗,并且这些病例都不抽烟。23例慢性风湿性关节炎患者中,10例有牙龈炎,9例有牙周炎。慢性风湿性关节炎患者与健康受试者相比,前者表现出牙周袋深度增加,临床牙周附着丧失,探诊出血并有牙龈缝液的出现。23名患者中的6名患者体内有卟啉单胞菌属龈拟杆菌抗体,且这6名患者都有牙周炎。
尽管类风湿性关节炎患者做常规的牙科保健,但这些患者体内所有的微环境中都有明显的炎性标记分布,包括口腔内微环境。卟啉单胞菌属龈拟杆菌抗体被风湿病学家视为生物标志物,用来识别那些经过牙周治疗好转的病人。

Alexandria, Va., USA – The International and American Associations for Dental Research (IADR/AADR) have just released the fifth clinical supplement to the Journal of Dental Research (JDR). This peer-reviewed supplement encompasses all areas of clinical research in the dental, oral and craniofacial sciences.
As the first clinical supplement in 2015 (the fifth since 2012), this supplement brings together emerging contributions in discovery and translational science to clinical application for the healthcare community. This issue is dedicated to clinical and translational research, which is covered through a wide range of topics including the relationship between sleeping in dentures and pneumonia risks in the elderly, improving clinical trials in dentistry, predicting severe pain after root canal therapy, universal health coverage, tooth loss and atherosclerosis, and more.
This clinical supplement also includes a corresponding podcast to the featured free-access editorial titled “Universal Health Coverage: A Unique Policy Opportunity for Oral Health” by M.R. Mathur, D.M. Williams, K.S. Reddy and R.G. Watt. In the podcast, Richard Watt is interviewed by JDR Editor William Giannobile and JDR Associate Editor Jessica Lee, and he provides his perspective on the implications of universal health coverage to the oral health community.
“The Journal of Dental Research is excited to release its fifth clinical supplement,” said JDR Editor-in-Chief William Giannobile. “This supplement was created to provide a unique opportunity to publish the highest quality research articles on clinical and translational research. I thank the researchers who submitted their science for publication in this special issue.”
