Dentures Using 3D Printers

Developed jointly by the Brooklyn 3D printing startup and Valplast, a dental materials manufacturer, r.Pod® Desktop 3D Printer claims to be the only 3D printer optimized and approved for printing Valplast®, the leading brand of flexible nylon resin for partial dentures and appliances.

“The ability to create end-use parts is the most exciting feature of the r.Pod® printer. In the past dental thermoplastics had to be either injection molded or vacuum formed, but the possibility to now 3D print them opens up a whole new world of CAD/CAM materials that didn’t exist before. This is particularly interesting for those who work with digital impressions because now there is now a completely digital workflow for restorations like Valplast® that in the past required physical impressions and traditional fabrication techniques.” (Arfona CEO Justin Marks)

“We are thrilled that we can now move past the rapid prototyping stage and directly into additive manufacturing for Valplast® appliances. Our knowledge of partial denture fabrication coupled with the most cutting edge technology is a slam dunk for labs who wish to go fully digital in their denture department.” (Peter Nagy, CEO of Valplast International Corp)

Breaking News :Plaque HD®, produces statistically significant reductions in dental plaque

Breaking News :Plaque HD®, produces statistically significant reductions in dental plaque

plaquehd

The results released today from a randomized trial of a novel plaque identifying toothpaste, (Plaque HD®), show statistically significant reductions in dental plaque and inflammation throughout the body. Inflammation throughout the body is accurately measured by high sensitivity C-reactive protein (hs-CRP), a sensitive marker for future heart attacks and strokes. These results, published today online ahead of print in the American Journal of Medicine, with an accompanying editorial by the editor-in-chief, show that Plaque HD®, produced statistically significant reductions in dental plaque and inflammation throughout the body as measured by hs-CRP.

In this trial, all randomized subjects were given the same brushing protocol and received a 60-day supply of toothpaste containing either Plaque HD® or an identical non-plaque identifying placebo toothpaste. To assess dental plaque, all subjects utilized a fluorescein mouth rinse, and intraoral photographs were taken under black light imaging. For hs-CRP, levels were measured by an independent laboratory using an enzyme linked immunosorbent assay.

“While the findings on reducing dental plaque extend a previous observation, the findings on decreasing inflammation are new and novel,” said Charles H. Hennekens, M.D., Dr.P.H., senior author and first Sir Richard Doll Professor, and senior academic advisor to the dean in the Charles E. Schmidt College of Medicine at Florida Atlantic University.

Plaque HD® is the first toothpaste that reveals plaque so that it can be removed with directed brushing.

Porphyromonas gingivalis & Aggregatibacter actinomycetemcomitans associated with increased of pancreatic cancer. – Study

Porphyromonas gingivalis & Aggregatibacter actinomycetemcomitans  associated with  increased of pancreatic cancer. – Study

NEW ORLEANS: Research released Tuesday showed that two species of bacteria with impossibly long names, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans, were associated with a sharply increased risk of getting pancreatic cancer. The data showed that carrying both bacteria was linked to a 50 percent increased likelihood of contracting the cancer, said Jiyoung Ahn, associate director of population sciences at the Laura and Isaac Perlmutter Cancer Center at NYU Langone Medical Center.

Bacteria

The data doesn’t show a cause-and-effect relationship between the bacteria and pancreatic cancer, but it is a first step “in understanding a potential new risk factor,” Ahn said. The research was released at the American Association for Cancer Research meeting here in the form of an abstract.

Ahn acknowledged that scientists don’t yet know the answer to the big question: If those bacteria are culprits, how, exactly, do they contribute to an increased likelihood of pancreatic cancer? “We don’t yet know how oral bacteria affect the pancreas,” she said.

Lab Banking Of Teeth For Stem Cells With Hope To Find Cure In Future

Lab Banking Of Teeth For Stem Cells With Hope To Find Cure In Future

A Bay State lab that banks stem cells from people’s baby teeth for potential fixes to diabetes, spinal cord injury and other conditions has seen demand nearly double over the last year — though researchers have yet to develop any therapies using dental material.

Stem-Cell-Teeth

More than 1,000 parents have handed over their children’s baby and wisdom teeth to Store-a-Tooth in Littleton, between 2014 and 2015, up from around 600 the year before. Their hope is that pulp from youthful teeth may someday be medically useful.

Mary-Regina Bennett, a Franklin teacher whose 19-year-old son Patrick has type 1 diabetes, said, “The day he was diagnosed, his father and I sat down and made a decision: We said, ‘You can go positive with this or you can go negative.’ We decided we’d be positive. You have to manufacture hope in a child in a situation like this.”

Their dentist suggested that Patrick — diagnosed with diabetes at 3 1⁄2 and now a sophomore at the University of Massachusetts Amherst — store his wisdom teeth after removal.

The idea is that eventually the stem cells in his teeth might be used to grow new pancreatic cells that would regulate his insulin in a way that his body can’t, said Peter Verlander, chief scientific officer of Provia Laboratories, which owns Store-a-Tooth.

The process costs $849 to $1,749, with additional annual storage fees of $120. That financial outlay by families carries no guarantee the material will ever be useful.

Umbilical cord blood stem cells already are being used as an alternative to bone marrow transplants for blood diseases such as leukemia. Verlander said the hope is that cells from teeth could be used to grow solid tissue.

But unlike cord blood, therapies using tooth pulp have yet to be shown as a realistic option, said Dr. George Daley, medical directory of the stem cell transplantation program at Boston Children’s Hospital, which is not involved with the tooth bank.

“Any use of dental pulp stem cells is highly speculative,” Daley said. “There are no proven medical applications, although there is much research underway.”

Combining Dentistry & Primary Care – A Harvard Initiative

Combining Dentistry & Primary Care – A Harvard Initiative

If you had pneu­monia, you prob­ably wouldn’t attribute it to tooth plaque. But North­eastern Uni­ver­sity and the Har­vard School of Dental Med­i­cine want you to start thinking that way.

dentmedi

It’s an interdisciplinary idea that has teeth: Your mouth, noted the U.S. surgeon general in the Oral Health in America report, provides a window into your overall health.

Now, a research team led by Maria Dolce, an associate professor in the School of Nursing at Northeastern, will make that idea a reality.

The two schools are joining forces to launch the Nurse Practitioner-​​Dentist Model for Pri­mary Care, inspired by the belief that oral health should be part of rou­tine med­ical care. The idea of inte­grating den­tistry and pri­mary care has been in cir­cu­la­tion for years, but North­eastern and Har­vard are bringing it straight to the clinic with the help of $1.2 mil­lion in funding from the U.S. Depart­ment of Health and Human Ser­vices’ Health Resources and Ser­vices Administration.

“Harnessing the power of dentistry and nursing is a cutting-edge model of care that enhances health-professions education and offers patients access to health-care that they otherwise might not have,” says School of Nursing Dean Nancy P. Hanrahan. “Maria Dolce is a national thought leader in this new model.”
