牙根尖部炎症增加心脏病风险

      HELSINKI, Finland, Aug. 2 (合众国际社UPI)  摘要_研究发现有齿科问题的会增加心脏疾病的风险。以前的研究也表明即使小规模的炎症也能诱发一系列疾病包括心脏病。
      研究人员说齿根炎症是一种免疫反应,牙髓炎症感染比较常见。有时炎症是没有症状的,需要通过X射线检查诊断。
      该项研究将平均62岁有心脏病症状的508名患者做X线造影术检查,其中123人没有冠心病,184例是稳定性冠心病和169例是急性冠脉综合征。确认心脏有问题占近70%。
      并发现58%以上有牙齿或颌骨的炎症性病变和高浓度的炎症血清抗体。
      赫尔辛基大学(University of Helsinki)的John Liljestrand说“需要根管治疗而未治疗者的急性冠脉综合征是一般患者2.7倍” 该研究报告发表在牙科研究杂志上。

HELSINKI, Finland, Aug. 2 (UPI) -- Dental root tip infections -- relatively common and often symptomless -- increase risk for heart disease, researchers found in a new study.
More than half the participants in a study of heart disease patients in Finland also had dental root tip infections, report researchers at the University of Helsinki, adding to growing evidence that dental problems increase risk for heart disease.
Low-grade inflammation caused by a range of dental conditions, including periodontal disease, has been linked to heart disease in previous studies.
Dental root tip infection is an immune response to infection of dental pulp, the most common cause of which are cavities. The infections are often symptomless and detected by chance in X-rays, researchers say.
For the study, published in the Journal of Dental Research, researchers took angiograms of 508 patients with a mean age of 62 who had symptoms of heart disease, 123 of whom did not have coronary heart disease, 184 had stable coronary heart disease and 169 had acute coronary syndrome.
The researchers report 58 percent of the participants had one or more inflammatory lesions in their teeth or jaws, finding high levels of serum antibodies linked to infection in participants with one or more lesion.
While root canal can clear the infections, more research is needed on whether the treatment reduces risk of heart disease -- though researchers say it's worth it to have the procedure anyway.
"Acute coronary syndrome is 2.7 times more common among patients with untreated teeth in need of root canal treatment than among patients without this issue," John Liljestrand, a researcher at the University of Helsinki, said in a press release.
