Nearly Half of American Adults Have Periodontal Disease

Over 47 percent of the U.S. adult population aged 30 years and older have mild, moderate or severe periodontitis, according to new research from the Centers for Disease Control and Prevention (CDC). In addition, nearly two-thirds (64%) of adults over age 65 have moderate to severe forms of periodontal disease.

These findings are based on epidemiologic data from the 2009–2010 National Health and Nutrition Evaluation Survey (NHANES), which included full-mouth periodontal examinations to obtain more accurate estimates of the prevalence and extent of periodontal disease in the United States. The study, published online in the October 2012 issue of the Journal of Dental Research, was developed in collaboration with a CDC Periodontal Disease Surveillance workgroup, which included representatives from the American Academy of Periodontology (AAP).

HPV-Associated Oropharyngeal Cancers Increasing in the U.S.

The new publication is titled the “Annual Report to the Nation on the Status of Cancer, 1975-2009.” Among the Annual Report’s primary findings on HPV-associated oropharyngeal cancer:

•From 2005 to 2009, incidence rates were four times higher among men than women (8.2 versus 1.8 cases per 100,000 persons, respectively), with the highest incidence rates found in white and black men (8.5 and 7.9 cases per 100,000 persons).

•Incidence rates of HPV-associated oropharyngeal cancer increased among white men (3.9%) and women (1.7%) over the same time period.

•Of the 13,446 new HPV-associated cancer cases among men in 2009, 78.2% were HPV-associated cancers of the oropharynx.

•Although cervical cancer remains the primary HPV-associated cancer among women, comprising 53.4% of U.S. cancer cases in 2009, 11.6% of HPV-associated oropharyngeal cancers also occurred in women.

Detecting Early Tooth Decay

“Both low-coherence light and ultrashort laser pulses can be used to measure internal structure in biological systems. An optical signal that is transmitted through or reflected from a biological tissue will contain time-of-flight information, which in turn yields spatial information about tissue microstructure.”

So began Huang et al. 20 years ago in the journal Science to describe their initial efforts to adapt a non-invasive fiberoptic imaging technique called optical coherence tomography, or OCT, to view tissues in the body. In this case, they visualized the retina and coronary artery. Five years later, Colston et al. applied OCT to the periodontal tissues of a pig, showing clearly the physical boundaries of the gingiva from the tooth and the tooth’s enamel from the cementum. This study marked the first time that OCT had imaged a hard biologic tissue successfully.

Since these groundbreaking papers, OCT is often employed with a polarization sensitive (PS) feature, creating the designation PS-OCT. The PS feature eliminates reflection from the tissue surface and monitors changes to the incident polarized light due to structural changes in the tissue.

Study Warns of Killer Bugs in Dentures

A new study has warned that dentures, despite its clean look, could be teeming with killer bugs like MRSA.

Researchers have advised that putting infected false teeth in a microwave oven for three minutes makes them safe.

Dentures are known to get covered with thin layers of bacteria called biofilms, which can lurk until they are breathed into the lungs.

Nearly 20 million people in the U.S. wear full or partial dentures often infected with MRSA or drug-resistant staphylococcus aureus bacteria.

A point pollution source, not only of mercury but also of other amalgam constituents

Shraim A, Alsuhaimi A, Al-Thakafy JT Taibah University, Faculty of Science, Chemistry Department, Al-Madinah Al-Munawarah, Saudi Arabia; University of Queensland, National Research Centre for Environmental Toxicology (EnTox), 39 Kessels Road, Brisbane, QLD 4108, Australia. Current literature suggests that amalgam waste from dental clinics is a point-source of mercury pollution in the environment. However, apart from mercury, other amalgam constituents (e.g. Ag, Sn, Cu, and Zn) in dental clinics' wastewater have not been reported in the literature before. The objective of this study was to evaluate the concentrations of mercury and other metals in the wastewater of some dental clinics and the influent of a wastewater treatment plant in Al-Madinah Al-Munawarah (KSA). This renders dental clinics wastewater a hazardous waste which should be properly treated before it is discharged into the environment.

More Americans seeking dental treatment at the ER

By LINDSEY TANNER AP Medical WriterAssociated Press

CHICAGO—More Americans are turning to the emergency room for routine dental problems—a choice that often costs 10 times more than preventive care and offers far fewer treatment options than a dentist's office, according to an analysis of government data and dental research.

Most of those emergency visits involve trouble such as toothaches that could have been avoided with regular checkups but went untreated, in many cases because of a shortage of dentists, particularly those willing to treat Medicaid patients, the analysis said.

The number of ER visits nationwide for dental problems increased 16 percent from 2006 to 2009, and the report released Tuesday by the Pew Center on the States suggests the trend is continuing.

Unhealthy Gums Increase Risk of Premature Delivery

Gum disease can do more than affecting just your gums. It can increase the risk of diabetes, cardiovascular disease and premature delivery. The following is the conclusion arrived at a conference on periodontal disease, held at New York.

Participants at the conference highlighted the accumulating evidence regarding increased risk of serious illness in association with gum disease. They further reflected the need for a collaborative work between both dentists and medical health professionals.
