Dentin Grows More Brittle With Age

Just about everyone knows that our bones grow more brittle and susceptible to fracture with age. But bones aren’t the only hard tissue in the body that might be a problem in our latter years. A number of studies indicate that dentin, the load-bearing core of our teeth located below the enamel, tends to become brittle and fracture more easily with age, potentially leading to the expensive repair or extraction of an otherwise healthy tooth. The problem has been poorly appreciated for centuries – and with good reason. Until a generation ago, most seniors already had lost most or all of their natural teeth by their retirement years. With more seniors now keeping their teeth for a lifetime, dentists have begun to ask why and how dentin fractures occur and whether anything can be done to prevent the problem.

Periodontal Disease Could Be Treated With Fish Oil Supplements

Periodontitis, inflammation of the tissue surrounding the teeth, affects more than half of adults and is linked to an increased risk of stroke and other heart problems. To evaluate whether fish oil supplementation could be an adjunct therapy for periodontitis, Dr. Alison Coates from the University of South Australia and colleagues from the School of Dentistry at University of Adelaide in Australia reviewed evidence from eight unique studies that involved humans.

Their review of these studies showed that improvements in clinical measures were common in all studies, but were scientifically significant in two that used a combination of fish oil and aspirin. Although this is not conclusive evidence, intake of fish oil is recommended for health benefits beyond the teeth.

Heart Disease and Tooth Loss

The study was conducted by state health agencies and was assisted by the Centers for Disease Control and Prevention. The Behavioral Risk Factor Surveillance System survey conducted between 1999 to 2002, included more than 40,000 adults aged 40 to 79, from 22 different states.

Even though smoking is linked to oral cancer, heart disease, gum disease and tooth loss, this study shows a significant connection between heart disease and tooth loss among participants in the age group of 40 to 59 who have never smoked.

Immune Peptide Shows Potential to Help Diagnose Oral Cancer

A team of NIDCR supported scientists discovered something quite interesting about cultured oral keratinocytes, cells that form the lining of the mouth and its soft tissues. The scientists confirmed that when pathogens challenge oral keratinocytes, these cells produce a variety of short antimicrobial peptides called β-defensins. What made the discovery interesting is that the β-defensins were differentially expressed when exposed to different immune signaling molecules. The implication being, not all β-defensin responses are the same. This finding matched up well with the many tasks that these peptides perform, from serving as the keratinocyte’s first line of defense to signaling nearby white blood cells to attack an invading pathogen. The finding also made sense on the DNA level. Defensins arise from 28 putative DNA coding regions that could be variably transcribed to suit the cell’s immediate needs. As members of the group later wrote, “This heterogeneity suggests that different phenotypic profiles exist that may affect an individual’s susceptibility or resistance to disease.”

ldhood Dental Problems Linked To General Health Problems Later On?

The University of Queensland Children's Nutrition Research Center at the School of Medicine and the School of Dentistry are looking for volunteers aged two, six and ten years for a new study, which aims to establish whether children may be changing their diets to eat unhealthy food because of dental problems and therefore submitting themselves to a higher risk of obesity and chronic disease in later life.

The researchers are particularly interested in recruiting children that were born prematurely, given that research has provided evidence that pre-term children are more likely to experience feeding and dental problems compared with children born at full term. Pre-term children also tend to have a higher risk of chronic diseases, like type 2 diabetes and cardiovascular disease in later life.

Rapid Test for Sjögren’s Syndrome

A team of NIDCR scientists reported in August that an experimental laboratory test called LIPS had correctly identified a key antibody associated with primary Sjögren’s syndrome three out of four times and with perfect accuracy. These data represented a significant improvement over the sensitivity and specificity of today’s standard ELISA assays. Now, the scientists report in the October issue of the Journal of Translational Medicine that this two-hour test just got a whole lot quicker. The scientists streamlined the assay’s two one-hour incubation steps to five minutes each. As the author’s reported, their quicker technique called QLIPS “includes a 5 minute set-up, two five-minute incubation steps, 10 minutes of washing and reading of the [testing] plate with a luminometer” for the results. Total testing time: About 25 minutes. Today’s ELISA tests typically range from five hours to a day to complete.

Gum Disease Linked to Pancreatic Cancer

A new study from Harvard has linked gum disease, also known as periodontal disease, to pancreatic cancer. Pancreatic cancer has been named as the fourth leading cause of cancer deaths in the United States. According to the Harvard School of Public Health , more than 30,000 Americans are expected to lose their lives to pancreatic cancer this year.

While there have been many studies documenting the link between poor oral hygiene and other medical problems, such as heart disease and stroke, this is the first study to find a solid link that gum disease could actually increase the risk of pancreatic cancer.

Sports and Energy Drinks Cause Permanent Tooth Damage

Consumption of sports and energy drinks cause irreversible damage to teeth, say researchers.

And energy drinks are twice as likely to destroy enamel than sports drinks.

"Young adults consume these drinks assuming that they will improve their sports performance and energy levels and that they are 'better' for them than soda," said Poonam Jain, BDS, MS, MPH, lead author of the study.
