Study Links Oral Bacteria and VAP

Every day in emergency rooms across America, hospital staff must insert plastic ventilation tubes into the airways of their sick or severely injured patients to keep them breathing. Unfortunately for those who have the tubes in place for 48 hours or longer, at least one in 10 will develop a bacterial infection in their lungs. In some cases, the resulting pneumonia will prove fatal. In others, the infection – known as ventilator-associated pneumonia, or VAP - will prolong the patient’s hospital stay from two weeks to a month on average, often resulting in extra hospital fees of $40,000 or more.

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.

Periodontal Disease in Senior Men

In the June issue of the journal Gerodontology, NIDCR grantees and colleagues provide some interesting new data on the periodontal health of older men. The data are from the MrOS dental study, a component of the Osteoporotic Fractures in Men (MrOS) study that is under way at research sites in Portland, Oregon and Birmingham, Alabama. In the reported study, dentists and hygienists offered half-mouth periodontal examinations to 1,347 study participants. The men were mostly Caucasian, averaged 75 years of age, and nine out of 10 retained their natural teeth. But, as the authors noted, they formed an especially unique research cohort. The men were highly educated, largely in good to excellent health, most visited the dentist annually, and 37 percent had never smoked.

Early Success Using Saliva to Detect Oral Cancer

Scientists funded by the National Institute of Dental and Craniofacial Research, part of the National Institutes of Health, reported today taking a major step forward in using saliva to detect oral cancer. As published in the current issue of Clinical Cancer Research, the scientists found they could measure for elevated levels of four distinct cancer-associated molecules in saliva and distinguish with 91 percent accuracy between healthy people and those diagnosed with oral squamous cell carcinoma.

This so-called "proof-of-principle" study marks the first report in the scientific literature that distinct patterns of "messenger RNA" not only are measurable in saliva but can indicate a developing tumor. Messenger RNA (mRNA) is the molecular intermediate between gene and protein, serving as a chemical record that an individual gene has been expressed.

According to David Wong, D.M.D., D.M.Sc., a scientist at the University of California at Los Angeles (UCLA) School of Dentistry and senior author on the paper, it may be possible with further refinement of the test, possibly by including additional cancer-linked mRNAs, to attain the necessary 99 to 100 percent accuracy of commercial diagnostic tests for oral squamous cell carcinoma, the sixth most common cancer in the United States. Wong noted that currently no biochemical or genetic diagnostic tests are commercially available for oral cancer.

Autofluorescence aids early oral cancer detection

By DrBicuspid Staff

June 26, 2012 -- Autofluorescence imaging and spectroscopy can assist clinicians in identifying early oral cancer and advanced dysplasia in high-risk individuals, according to a study presented last week at the International Association for Dental Research meeting in Brazil.

In an ongoing clinical protocol, researchers from the University of Texas MD Anderson Cancer Center, Rutgers University, Rice University, and University of Texas Dental Branch at Houston obtained autofluorescence imaging and depth-sensitive spectroscopy data of patients with potentially malignant oral lesions and/or a history of oral cancer.

Xylitol Syrup Helps to Prevent Childhood Tooth Decay

One hundred and forty years ago this December, an Ohio dentist named William Sample received the first patent on chewing gum. His recipe: rubber, sugar, licorice, and charcoal. Although Sample never actively pursued the patent, many subsequently wiled away a precious hour adding and subtracting ingredients to his crude, chewy concoction. Among them was Walter Dierner, an accountant in the 1920s for the Fleer Chewing Gum Company in Philadelphia. When the 23-year-old Dierner wasn’t crunching numbers, he dabbled on the side with his homespun chewing gum recipes. One day Dierner got his latest recipe wrong and “ended up with something with bubbles.” As Dierner recalled, his colleagues at Fleer recognized the novelty of “bubble gum” and launched plans to manufacture it. To show just how different bubble gum was from regular chewing gum, Dierner and company decided to give it a different look. The men dashed off to find a bottle of food coloring to do the trick, and by chance the only one to be found in the entire factory was pink. The rest is history.

Researchers Find Joint Failures Potentially Linked To Oral Bacteria

The culprit behind a failed hip or knee replacements might be found in the mouth. DNA testing of bacteria from the fluid that lubricates hip and knee joints had bacteria with the same DNA as the plaque from patients with gum disease and in need of a joint replacement.

This study is one of many coming from the Case Western Reserve University School of Dental Medicine that have linked oral bacteria to health problems when they escape from the mouth and enter the blood.

Gum Disease in Elderly Linked to Low Protein Levels

Low levels of a protein known as Del-1 may be the cause of gum diseases in older people according to a new study published in the journal Nature Immunology.
br/> Researchers from the Queen Mary University of London conducted the study on a group of young and old mice and found that low levels of Del-1 in older mice led to severe gum disease and bone loss.
<br/> <br/>Del-1 has been found to make the immune system prevent white blood cells from sticking to and attacking the mouth tissue.
