Link between hair disorders and susceptibility to dental caries
International & American Associations for Dental Research via ScienceDaily
Hair and teeth are ectodermal appendages that share common developmental mechanisms. However, the major structural components making up hair and teeth are very distinct. The hair shaft is essentially made of keratin filaments that are highly cross-linked. Tooth enamel matrix is primarily composed of enamel proteins that are degraded and replaced by minerals during enamel maturation. Fully mineralized enamel contains a small fraction of cross-linked organic material that has not been fully characterized. In this study, researchers assessed the presence and functionality of a specific set of hair keratins in this organic fraction of enamel.More

Graphene: A new tool for fighting cavities and gum disease?
R&D Magazine
Dental diseases, which are caused by the overgrowth of certain bacteria in the mouth, are among the most common health problems in the world. Now scientists have discovered that a material called graphene oxide is effective at eliminating these bacteria, some of which have developed antibiotic resistance. They report the findings in ACS Applied Materials & Interfaces.More

Emergency dental visits go up 64 percent day after St. Patrick's Day
Yes, it may seem like an extreme stereotype to assume that people get drunk on St. Patrick's Day, to the point that they'd be in bar fights and knock each other's teeth out, causing them to have to go to the dentist the next day. But it's true. Oh yes, it's true. According to data provided to CNBC by Sikka Software, emergency visits to the dentist skyrocket by 64 percent across the country.More

Water fluoridation debate reignites in western Pennsylvania
The Associated Press via Idaho Statesman
Debates come and go, but there's one — the seven-decades-old battle over fluoridating drinking water — that appears to be rekindling in western Pennsylvania. Officials in Brackenridge were set to remove fluoride from the town's water supply a few weeks ago. Then the borough's switchboard began to light up. It's a fervent discussion that dates back to the 1940s, when researchers found people living where water supplies had naturally occurring fluoride at certain levels had fewer dental cavities than those living in areas with lower levels.

How weather can affect teeth and oral health
Spring is on the horizon, or at least, we hope it is. When the months of frigid cold are finally behind us, we can look forward to warming temperatures, allergy season and hot, humid weather.
