Periodontal pathogens enhance HIV-1 promoter activation in T cells
During the 39th Annual Meeting of the American Association for Dental Research, convening at the Walter E. Washington Convention Center in Washington, D.C, lead researcher O.A. Gonzalez (University of Kentucky, Lexington) presented a poster of a study titled "TLR2 and TLR9 Activation by Periodontal Pathogens induce HIV-1 Reactivation." Although oral co-infections (e.g. periodontal disease) are highly prevalent in HIV-1 patients and appear to positively correlate with viral load levels, the potential for oral bacteria to induce HIV-1 reactivation in latently infected cells has received little attention.More

Dentist: Beware of imported dental implants
Dr. Craig Spodak is concerned about an increasing number of dental implants, bridges and crowns that are being manufactured overseas in countries like China and India for about one-sixth the cost. But with less guarantee of regulation, he says, the imported products have shown dangerous levels of toxic chemicals in rare cases. The long-term effects are still unknown, and many patients in the U.S. have no idea their dental items are being made elsewhere.More

Successful treatment of periodontal disease lowered preterm birth incidences
Previous studies have explored the effect of periodontal treatment, irrespective of efficacy of treatment, in reducing infant prematurity. In a study titled "Risk of Preterm Birth is Reduced with Successful Periodontal Treatment," lead researcher M. Jeffcott, and colleagues S. Parry and M. Sammel (all from the University of Pennsylvania, Philadelphia) and G. Macones (Washington University, St. Louis, Missouri) determined whether a reduction in infant prematurity was associated with successful periodontal treatment.More

The Herald Dispatch
In severe gum disease, the tissue involved is approximately the same size as the skin on the back of your hand. What would you do if the back of your hand were red and swollen, and bled at the slightest touch? You'd haul your buns to the doctor. One way to keep yourself from getting anywhere near that stage of periodontal disease is by adding green tea to your daily menu. In one study, the more green tea men drank, the better their gums fared during dental exams.More

Small-business tax breaks in 2010
U.S. News & World Report
This year, taxes on small-business owners are under particular scrutiny. They're getting so much attention because Congress is currently debating a jobs bill with multibillion-dollar tax credits for small businesses. Recently, the Senate passed a bill with a payroll tax holiday for business owners and their employees and an extension of a tax deduction on capital expenditures. The payroll tax holiday -- dubbed the Hire Now Tax Cut -- allows an employer to forgo payroll tax on any unemployed person hired by the firm this year.More

A peri-implantitis update
Dentistry iQ
I recently scheduled a periodontal maintenance appointment with my talented periodontal co-therapists, Laurie Cason, RDH, and periodontist Jeffrey S. Sherry, DDS. I trust them completely, enjoying our visits. Laurie recently lost an implant to peri-implantitis. Her implant was placed 10 years ago, and it was difficult for her to face the terminal inflammation and sudden loss of supporting bone.More

Business owners can avoid common tax time pitfalls
The Associated Press
Small business owners who compile their own income tax returns can find themselves falling into some common quicksand pits. The mistakes can be costly if they raise a company's tax bill unnecessarily or subject it to penalties and interest in the future. Some of the problems are mechanical in nature, such as not filling out the right forms. Others are more strategic, including not considering how the deductions you take on your 2009 return might affect your taxes in future years.More
