Researchers at the University of Iowa have created an implantable bio patch that regrows bone in a living body, using existing cells. The team created a scaffold seeded with plasmids containing the genetic information for producing bone. The plasmids are absorbed by bone cells already in the body, spurring new growth. Potential applications extend to dentistry. Results appear in the journal Biomaterials.
SLU Orthodontics resident offers tips to maintain good oral health during the holiday season
The bacteria in the human mouth – particularly those nestled under the gums – are as powerful as a fingerprint at identifying a person’s ethnicity, new research shows.
Cavities and other dental problems develop over time; Halloween candy is not to blame.
“Every week we see patients that are older, in their 30s, 40s and 50s who complain that at a much younger age such as in childhood, their previous dentist was rough, did not explain what was happening, carelessly drilled or poked and prodded and the memory is so fresh that they still feel anxiety as an adult,” says Martin Hogan, DDS, Loyola University Health System. “Unfortunately, years of missing dental cleanings and routine visits means they often come in to see us as a last resort when they are suffering a really painful condition.
Oral pain that feels like a scalded mouth and can last for months has baffled dental researchers since the 1970s, when burning oral sensations were linked to mucosal, periodontal, and restorative disorders and mental or emotional causes.
A big sack of candy is the top priority of children at Halloween but with some easy substitutions, adults can offers kids treats that preserve dental health and Halloween fun. "Every year right after Halloween I get emergency visits from parents with kids who have damaged teeth caused by Halloween candy," says Martin Hogan, DDS, division director of dentistry, Loyola.
More than dentures or bridges, implants mimic the look and feel of natural teeth. Still, they are costly, and a small percentage either fall out or must be removed. Tolou Shokuhfar wants to lower that failure rate to zero.
Poor oral health, including gum disease and dental problems, was found to be associated with oral human papillomavirus (HPV) infection, which causes about 40 percent to 80 percent of oropharyngeal cancers, according to a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research.
Researchers from Case Western Reserve University School of Dental Medicine have discovered how a common oral bacterium can contribute to colorectal cancer.
In the last 25 years, Kim McFarland, D.D.S., University of Nebraska Medical Center College of Dentistry in Lincoln, has seen an increase in the number of dental patients with erosion of the tooth enamel – the protective layer of the tooth. Once erosion occurs, it can’t be reversed and affects people their whole life.
It seems logical that a preventive check-up will deter cavities and other costly dental problems in children, but new UAB research shows otherwise.
Researchers from Tufts University School of Dental Medicine have discovered an association between local dental anesthesia given to children ages two to six and evidence of missing lower wisdom teeth. The results of this epidemiological study suggest that injecting anesthesia into the gums of young children could interrupt the development of lower wisdom teeth.
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.
After reviewing previous research on gum disease and obesity, researchers found inflammation is the association between both health problems, which they describe in the Journal of General Dentistry article, “Obesity and periodontitis: a link.”
Heavy coffee drinkers have a lower chance of dying from oral cancer, says new American Cancer Society research but a Loyola dentist is still not ready to recommend coffee drinking to his patients.
Obesity and dental cavities increase and become epidemic as children living below the poverty level age, according to nurse researchers from the Case Western Reserve University and the University of Akron.
Characteristics of both patient and surgeon can affect the success of dental implants. A 10-year study finds that patient risk factors such as grinding teeth or diabetes increase the odds of implant failure. It also associates higher implant failure rates with surgeons who have less than 5 years of experience.
For a successful dental implant, the first step for some patients is reconstructive surgery of the jaw. A bone graft to augment the upper jaw can now be achieved by several methods. To assess these methods, their risk of sinus perforation, and the best evaluation technology, researchers put these procedures to the test on 20 human cadaver specimens.
