Inflammation of the gingiva: The other reasons besides the obvious
Gingival inflammation usually is attributed to bacterial-induced gingivitis and/or periodontitis. Although bleeding most often is caused by this etiology, there can be other systemic issues at work. The most common of these entities are the diseases listed under the category desquamative gingivitis. Desquamative gingivitis is a clinical term used to characterize attached and/or free (marginal) gingiva that demonstrates epithelial erythema and erosion. Desquamative gingivitis can be seen alone or with focal areas of ulceration. When a patient presents with desquamative gingivitis, the most common diseases or disorders that may be causing the problem include the following.More

Cigna study supports association between treated periodontal disease and reduced hospital admissions, ER visits, lower medical costs
Regular visits to the dentist may do more than just brighten your smile; they also may lead to fewer hospital visits and trips to the emergency room, as well as lower your medical costs. These are the conclusions from a three-year Cigna dental study that looked at the potential benefits of treated periodontal disease. The findings were presented at the International Association for Dental Research conference in Seattle.More

Really? Treating sleep apnea reduces inflammation
The New York Times
Doctors have plenty of good reasons to persuade people with sleep apnea to get it treated. The widespread disorder causes disruptions in breathing at night, which can ruin sleep and raise the likelihood of problems like obesity and fatigue. The standard treatment for the condition, a mask worn at night that delivers continuous positive airway pressure, or CPAP, significantly improves apnea, even though many people don't like to wear it. But the mask may do more than restore normal breathing at night. Some research suggests it reduces inflammation, benefiting overall health.More

Gum disease treatment can lower annual medical costs for individuals with rheumatoid arthritis and women who are pregnant
PR Newswire
Annual medical costs are lower by $3,964 for individuals with rheumatoid arthritis and $2,430 for pregnant women when treated for gum disease, according to a fourth round of findings from an oral health study by United Concordia and Highmark Inc. "The latest findings from our landmark study continue to clearly demonstrate the importance of good oral health," said Dr. James Bramson, chief dental officer for United Concordia. "Plenty of research exists that shows good oral health can impact overall health; however, this study &mdsah; and its four round of findings — reveals the financial repercussions that could be realized by failing to prevent or treat dental disease."More

Common test for measuring mercury may overestimate exposure from dental amalgam fillings
Medical News Today
A common test used to determine mercury exposure from dental amalgam fillings may significantly overestimate the amount of the toxic metal released from fillings, according to University of Michigan researchers. Scientists agree that dental amalgam fillings slowly release mercury vapor into the mouth. But both the amount of mercury released and the question of whether this exposure presents a significant health risk remain controversial.More

Arizona bill would increase oversight of mobile dental services

State Rep. Doris Goodale, R-District 5, has introduced H.B. 2426, which would require double parental notification before a mobile dental unit can provide treatment to children: one for routine cleanings and sealants, and a second for irreversible procedures such as restorations or extractions.

Oral microbes differ between smokers, nonsmokers
Smokers have a richer population of microbes associated with periodontal disease than nonsmokers, according to research presented at the recent International Association for Dental Research meeting in Seattle. Matthew Mason, an oral biology graduate student at the Ohio State University College of Dentistry, described the efforts he and his co-investigators undertook to compare and characterize the oral microbial fingerprints of 100 smokers and 100 nonsmokers selected at random from the Columbus, Ohio, community. The participants were both periodontally and dentally healthy, had no known systemic diseases, and had not received a professional dental cleaning or antibiotics in the previous 90 days.
