The largest study of its kind finds that a history of frequent dental x-rays, particularly at a young age, is tied to an increased risk of developing meningioma, the most common type of primary brain tumor in the United States. Dr Elizabeth Claus, a neurosurgeon at Brigham and Women's Hospital (BWH), in Boston, and the School of Medicine at Yale University in New Haven, and colleagues, write about their findings in a paper due to be published in the journal Cancer on 10 April. Claus said in a statement: "This research suggests that although dental x-rays are an important tool in maintaining good oral health, efforts to moderate exposure to this form of imaging may be of benefit to some patients." Meningiomas arise in the "meninges", or the lining of the brain, and account for around 33% of all primary brain tumors in the United States.
A common and potentially debilitating non-cancerous brain tumor has been linked to dental X-Rays. Research from the Yale School of Public Health published online in Cancer, a journal of the American Cancer Society, says that people who received frequent dental X-Rays before doses were lowered, were more than twice as likely to develop the tumors known as meningioma. Meningioma is listed as a rare disease by the National Institutes of Health, with estimates showing around 8 people in 100, 000 thousand suffer from the problem, which occurs more frequently in women than men. The tumors develop in the membrane that surrounds the brain (meninges) and can go undetected for years. They have been reported to get larger than a baseball and while not cancerous, the invasion of the skull cavity can cause problems ranging from headaches and vision problems to loss of speech and motor control.
During the 41st Annual Meeting & Exhibition of the American Association for Dental Research (AADR), held in conjunction with the 36th Annual Meeting of the Canadian Association for Dental Research, an abstract titled "Periodontal Therapy Reduces Hospitalizations and Medical Care Costs in Diabetics" to determine if periodontal treatment was associated with the number of hospitalizations and cost of medical care among diabetics with periodontal disease. A longitudinal study compared medical costs for diabetic subjects with periodontal disease who received periodontal treatment versus periodontally untreated controls over a three year period. Subjects were enrolled in Highmark (Blue Cross) medical and United Concordia Companies, Inc. dental plans, and received medical and dental services.
Oral bacteria that escape into the bloodstream are able to cause blood clots and trigger life-threatening endocarditis. Further research could lead to new drugs to tackle infective heart disease, say scientists presenting their work at the Society for General Microbiology's Spring Conference in Dublin. Streptococcus gordonii is a normal inhabitant of the mouth and contributes to plaque that forms on the surface of teeth. If these bacteria enter into the blood stream through bleeding gums they can start to wreak havoc by masquerading as human proteins. Researchers from the Royal College of Surgeons in Ireland (RCSI) and the University of Bristol have discovered that S. gordonii is able to produce a molecule on its surface that lets it mimic the human protein fibrinogen - a blood-clotting factor.
During the 41st Annual Meeting & Exhibition of the American Association for Dental Research (AADR), held in conjunction with the 36th Annual Meeting of the Canadian Association for Dental Research, a symposium titled "Building the Oral Health Care Workforce: Multipronged Research on Dental Therapy" took place to help attendees understand opportunities for effective utilization of new workforce models in nontraditional settings within the oral health care community. For decades, the composition of the oral health care workforce in the United States consisted of dentists, hygienists, and assistants. These traditional team members are well established and there is a common understanding of their roles within the oral health care delivery model. However, in this study with the introduction of the dental therapist in Minnesota, different opinions have been formulated regarding their role on the oral health care team and their potential to impact the delivery of oral health care.
