We’re One Step Closer to Being Able to Regrow a Lost Tooth

We’re one step closer to being able to regrow a lost tooth, thanks to a new study showing it’s possible to grow multiple teeth from a single root. These teeth can then be implanted to become fully functional. Thus far it has only been tested in rats, but it could lead to a potential revolution in human dental care.

Why this over an implant?  Dentures are notorious for not staying seated, and the fit might not be that great to begin with.  A natural tooth would discolour, while implants are less likely.  Getting “full functionality” also means the ability to have another root canal 😉

Iron Is Better Than Fluoride At Preventing Cavities, But There’s A Catch

Materials scientists studying beavers have discovered why the crafty rodents never get cavities: the enamel in their teeth is rich in iron. Iron, they found, resists acid more effectively than fluoride.

…which means beaver teeth will have a reddish tinge to it.  From the blood of their enemies! 😉

Here’s the Weird Reason You Get Tartar On Your Teeth

Your body isn’t a finely-tuned machine. It’s a reinforced pile of goo that spends its day trading off costs and benefits. One of those costs is the tartar building up on your teeth because of the surprising source of your saliva.

I haven’t turned anything up yet, but the note about calcium coming from blood makes me wonder what or if there’s anything related to blood thinners on this.  I happen to cycle with two dentists regularly, so I’ll see if I can remember to ask.  But little to nothing on the internet suggests there’s no link or concern.

I had to look – there is vitamin K in coconut oil, but very little:

  • 1 cup/218 grams of coconut oil contains 1.1 mcg of vitamin K, 1% of the Daily Value (DV)

Looking at the other nutritional “value” the article claims – 0.1 mcg of iron for 1 cup of coconut oil is 0% DV.  And 2% DV of vitamin E.  Coconut oil has a lot of calories, from fat.

Your Own Body Smuggles In This Radioactive Particle

Strontium-90 is not good news. It emits ionizing radiation, which means you want to keep it out of our body. Unfortunately, your body has other ideas. The body’s own mechanisms welcome this isotope in, and store it away.

Strontium isn’t the only calcium mimic. Strontium-89 has been used to treat cancer spread to bones, but has largely been replaced by Samarium-153 which is less toxic. These are most commonly used in prostate cancer, but Radium-223 has superseded both in that disease as it is more effective and probably safer.

Why Lead Is Bad For Humans

Given that humans have been using lead in various product for over 8,000 years (with the first known mining of it in Anatolia around 6500 BCE), you might be surprised to learn that we have known that lead is dangerous and shouldn’t be trifled with since at least 150 BC, when its effects on the human body were noted by famed Greek physician Nicander of Colophon. Nicander even went so far as to describe the metal as “deadly”, writing extensively on the crippling effects it has on the human body in his work, Alexipharmaca.

Part of the reason for so many jokes about slack jawed yokels, pre-meth era, was that cider presses and stills tended to be made of lead.
