I no longer get excited about medical innovation because I know I'll never be able to afford to benefit from any of it. I'm lucky to have gotten vaccinated as a child while that was still legal for the poors

When I was a teenager it was announced that we would soon be able to stimulate the growth of brand new teeth, right in the mouth. I'm almost 50 and I need some new fuckin' teeth real soon.

[–] Jumpropegazing@lemmy.zip 4 points 1 day ago

its possible now but the world is pretty fucked. we can already reduce aging too and reverse it, we have cancer treatments that have near 100 percent success rates for many cancers, and many of these developments were only in recent years but when you watch how much gets done without making it into actual hospitals because of shitass companies and practices it makes you feel a little concerned if any of that will really have an impact, especially when everything is already burning anyway.....

There was a new development in japan less than a year ago. Downside is all your teeth fall out and all regrow

[–] pool_spray_098@lemmy.world 11 points 2 days ago (2 children)

I'm sorry, I thought you said there was a downside.

[–] frongt@lemmy.zip 8 points 1 day ago (2 children)

You think teething and a soft food diet isn't a downside? Any time I have anything done that requires soft food, I'm craving solid food within like three days. It sucks.

Given the state of my teeth, I'm not far from that anyway.

[–] dogs0n@sh.itjust.works 3 points 1 day ago (1 children)

It didn't sound like a big deal, but somehow you just instilled in me an existential dread of having no teeth to enjoy solid foods when craving some.

[–] SaveTheTuaHawk@lemmy.ca 7 points 2 days ago (1 children)

The problem is those new teeth were soft with no enamel. This could address that. Either way, no insurance will cover this and it will cost a fortune.

[–] jerkface@lemmy.ca 5 points 2 days ago

My teeth already have no enamel so I'm game.

Our medical knowledge is shockingly rudimentary. Why we can't coax cells to do what they did anyway before is something we really need to understand to pretend to have any kind of medical knowledge. What passes for medicine is nothing more than 19th century++. See this, do that, body will heal. That's about it. I'm shocked every time I see someone in a wheelchair, how can we have LLMs and hallucinated movies but not understand how a few milligrams of organic matter organizes into nerves? etc etc etc

I am hoping that the absolutely bonkers computing power we are currently wasting on fart videos will be used to simulate matter in the future, here's to cheering on the AI crash!

[–] Jumpropegazing@lemmy.zip 4 points 1 day ago

we do have the ability to coax cells and even turn differenciated cells into pluripotent stem cells we've been able to for years the people who did it won a nobel peace prize

[–] MumboJumbo@lemmy.world 7 points 1 day ago

In reality, AI will help solve a lot of our medical ignorance. Not the goofball LLMs, but specialized AI algorithms specifically geared towards niche medical research and applications. Don't let GPT and Gemini sour the potential of some possibly game changing software.

[–] frongt@lemmy.zip 6 points 1 day ago (1 children)

The human body is an immensely complex system of chemical reactions.

And before you say "simulate it", we don't have nearly enough computational resources to do that. Simple reactions or chains of reactions, yes, but even a simple body process consists of multiple steps and a number of large, complex molecules.

[–] Doomsider@lemmy.world 5 points 1 day ago* (last edited 1 day ago)

This right here. We can definitely model how a single chemical effects cells, but what about multiple chemicals together. The reality is we are still very far from simulating something like the side effects from multiple interacting drugs at once.

We will likely discover some incredible insights when we do this though.

[–] Soggy@lemmy.world 13 points 1 day ago (1 children)

We have a pretty good idea how things work during development, it's tricking those cells into the same process as a fully-formed organism that's hard. Isolating and distributing the hormones in the right way. I think you're underselling the complexity and scale of biology. We can't just put a tiny camera and chemo-sensor inside a neuron and see what's going on in real time and synthesize up a hundred thousand copies.

Hell yeah. I'm gonna overuse this shit and just have 2 gigantic teeth. One on the top and one on the bottom. No more flossing for me. Fuse those bad boys together. I'll have the smile of an N64 game character.

How many times have I read this headline....

[–] tempest@lemmy.ca 7 points 2 days ago (2 children)

Every time you read it it's in a mouse or a petri dish.

I wish they would put that on the headline.

According to the article, they used human teeth from cadavers

"Dental enamel has a unique structure, which gives enamel its remarkable properties that protect our teeth throughout life against physical, chemical, and thermal insults," said lead author Dr. Abshar Hasan

This man doesn't just disapprove of people mistreating their teeth, he is personally insulted by it. A true dentist.

[–] Deconceptualist@leminal.space 78 points 2 days ago (17 children)

I could never ever work in that field, it gives me the ick. So I appreciate people who can.

Also enamel is the hardest substance in your body; AFAIK chemically it is indeed interesting and hard (ha) to emulate with other bio-safe materials.

The researchers used extracted human molars as an ex vivo model, first etching their enamel or dentine surfaces with acid to mimic different stages of tooth erosion. They then applied a single coating of the biomimetic elastin-like recombinamer (ELR) gel and let it dry. Finally, the teeth were immersed in carefully controlled mineralization baths that replicated the ionic environment of saliva.

Keep in mind this hasn't been shown to actually help teeth in someone's mouth.

[–] Goretantath@lemmy.world 44 points 2 days ago (3 children)

Just from that, it seems like its a patch job, not capable of regrowing from zero.

How long until the dental restoration industry lobbies it out to be banned, so they can keep selling their photoshop jobs of people smiling with new teeth alongside crowns and implants, all at an inflated price?

[–] Wispy2891@lemmy.world 18 points 2 days ago (3 children)

It already happens with nano-hydroxyapatite pastes. In Europe you find them at the supermarket for 5 euro, in USA you need a prescription and it's sold for $$$

I've heard of stuff like this for well over a decade. Seems like there's a new article about teeth regrowth every month, either enamel or full teeth. Still waiting on real results.

Can they make one to generate beaver enamel? I will accept the red color if I can chew through a tree.

It would be really incredible if they can manage to make this an OTC offering. This is huge.

After reading that article, this feels like something that I would want a trained professional to oversee.

I bet the catch here is it could accidentally grow anywhere in the body as long as it mimics what our mouth has (saliva). Imagine growing enamel in our tongues or throat.
