Gum Disease

Nurses who care for patients with dementia now have a tailored approach to dental hygiene for their charges, thanks to a pilot study by a team of nurses. "Poor oral health can lead to pneumonia and cardiovascular disease as well as periodontal disease," said Rita A. Jablonski, even though these illnesses are not usually associated with the mouth.

Dr. Emil Kozarov and a team of researchers at the Columbia University College of Dental Medicine have identified specific bacteria that may have a key role in vascular pathogenesis, specifically atherosclerosis, or what is commonly referred to as "hardening of the arteries" -- the number one cause of death in the United States.

There is a close relationship between infection outbreaks on teeth and the presence of alopecia areata or localized alopecia, a type of hair loss which has an unknown origin. Alopecia areata starts with bald patches on the scalp, and sometimes elsewhere on the body. The disease occurs in males and females of all ages, and experts believe that it affects 1 out 1000 people.

Sex hormones may be the biological reason why men are at greater risk than women for destructive periodontitis, an infection of the gums, according to researchers at the University of Maryland Dental School.

Periodontitis, a common inflammatory disease in which gum tissue separates from teeth, leads to accumulation of bacteria and potential bone and tooth loss. Although traditional treatments concentrate on the bacterial infection, more recent strategies target the inflammatory response.

The prevalence of periodontal disease in the United States may be significantly higher than originally estimated. Research published in the Journal of Dental Research from the Centers for Disease Control and Prevention (CDC) and the American Academy of Periodontology (AAP) suggests that the prevalence of periodontal disease may have been underestimated by as much as 50 percent. The implication is that more American adults may suffer from moderate to severe gum disease than previously thought.

Plaque-causing bacteria can jailbreak from the mouth into the bloodstream and increase your risk of heart attack, says a scientist at the Society for General Microbiology's autumn meeting in Nottingham.

When lean healthy young adults gained about 9 pounds, the functioning of their blood vessel lining became impaired -- but shedding the weight restored proper functioning, according to a Mayo Clinic research report. The finding is important because this vessel disorder, known as endothelial dysfunction, is a predictor of heart attacks and stroke, and the effects of modest weight gain on the disorder were not previously known.

Why is it that two people can consume the same high fat, high-calorie Western diet and one becomes obese and prone to diabetes while the other maintains a slim frame? This question has long baffled scientists, but a study by Yale School of Medicine researchers provides a simple explanation: weight is set before birth in the developing brain.

NYU dental researchers have found the first long-term evidence that periodontal (gum) disease may increase the risk of cognitive dysfunction associated with Alzheimer's disease in healthy individuals as well as in those who already are cognitively impaired.

Researchers from Case Western Reserve University School of Dental Medicine and University Hospitals Case Medical Center report initial results from a small sample that inflammation from gum disease and prostate problems just might be linked.

Despite a massive global research effort, many basics of Alzheimer's disease onset remain elusive. This has hampered development of treatments effective during the earliest stages of the disease, when prevention is most likely. But a new discovery by University of Central Florida researchers has revealed a previously unknown mechanism...
