Robot dentist performs first human procedure (newatlas.com)

I'm way more interest robotic diagnosis than robotic treatment. It's so hard to trust dentists have your interest above their financial interest

This sounds more like a systemic issue than a technological one. New tech will most likely only support the current system (profit over people, in your case), and not magically make things fairer or more social.

I have an example that disagrees.

I had a stomach bug, and a Physician was insistent I get xrays. I put my symptoms into chatGPT, and it agreed that the xray was unnecessary.

I saved hundreds of dollars, I learned my doctor was corrupt, and tbh... I already knew what I had before going to the doctors. I only needed the doctor to write the prescription.

idiotsecant 3 minutes ago [-]
Have you considered that your doctor might have had an actual reason to want you to get an X-ray and that maybe chatgpt is wrong? Absolutely wild to me that you distrust a human but feel like a glorified autocomplete is somehow completely trustworthy. They can both lie, but at least the human knows they are lying.
pas 5 hours ago [-]
Probably it's both. If it would be really that easy to tell honest dentists (and society) would have no problem exposing the fake ones.

But in many cases dentists do protective/proactive treatment... that "brow spot looks like something, and maybe it's nothing, but let's make sure ..." ... which, yes, is reducing the number of cavities (by definition), but you have to get through the process. And if you have those spots for decades there's a good chance they would have continued to be nothing for more decades.

Even with Xray it's an educated guess. (I mean in cases when someone goes for a checkup.)

... but there's the non-tech aspect, meaning that the application of dental sealants seem to be spreading slower than warranted.

Using robots does not change any financial incentives. This is true for operations as well as diagnosis.
dotancohen 3 hours ago [-]
Diagnosis is currently extremely subjective. I believe that GP is suggesting that robotic diagnosis will be more objective and determinant. Ostensibly, because financial considerations will not be part of the input to the diagnosis routine.

That said, financial considerations will probably still be a big part of the treatment routine.

Zambyte 3 hours ago [-]
> Ostensibly, because financial considerations will not be part of the input to the diagnosis routine.

Devices that overreport are likely to be more popular and more common than devices that underreport. That is in part due to the financial incentives associated with diagnosing.

I'd like to see it change the way dental insurance works, so that e.g. an AI diagnosis will legally be fully covered by the insurance, and anything that can't be verified through that would be considered an elective procedure. In the US dental insurance works basically opposite of health insurance - they only cover the basic checkups and you have to pay for any real medical needs. It's like if car insurance only covered oil changes and tire rotations but not accidents

What makes you think that the robot won't have a financial interest? The company that makes it will want a profit. The dentist that buys it wants to make a profit. If there's an AI under the hood, it might decide that someone needs to pay for its electricity habit.

That being said, I agree that it's a difficult part of the fee-for-service model.

If the robot's decision-making process is transparent then 100% agreed.

Will robot dentists facilitate the option to lay face down for procedures so that the debris and saliva falls out instead of needing the suction tool?
worstspotgain 20 hours ago [-]
This, and the fact that a sterilized robot is way less likely to transmit airborne pathogens than a dentist and an assistant wearing a surgical mask at best. Maybe not v.1.0b4, but I'd sign up for v.1.2.
enumjorge 13 hours ago [-]
Maybe I'm out of the loop, but is this a known issue? As in, are dental offices a higher risk location for diseases to spread?
worstspotgain 12 hours ago [-]
Well your mucosa is more exposed than it normally is. Your mouth is acting like a receptacle, particularly when you're not wearing a dental dam. The probability that a larger pathogen-containing droplet will randomly fall in is much higher.

Larger droplets normally fall straight to the ground. Smaller droplets can be sucked in by breathing in no matter what, so the probability for those is equivalent to just being near someone. However, depending on the pathogen, risk can scale much more than linearly with droplet size. Overall risk is probably in the ballpark of an unmasked in-your-face shouting match with someone.

Then as someone else mentioned, any fomites can transfer from anything non-sterile that the dentist or assistant touches. There can also be aerosol-generating procedures in other rooms, though the robot wouldn't help there (they'd need a negative air pressure system.)

This discusses some of the risks, but mostly from the standpoint of protecting the providers from the patients: https://www.ncbi.nlm.nih.gov/books/NBK589669/

Every dentist I go to use single-use thin nitril or similar gloves. If they have to use any of the non-sterilisable equipment (like the mouse or kb), they take said glove off before use and put on a new one after.

I mean that’s just common sense, surely.

Alibaba has a "search by image" feature. It has been the BEST weapon to catch dropshipping.

As a bonus, if it's on Alibaba, you can either A: order a sample direct cheap or B: find the product on Aliexpress and order that way for cheap, too. I love catching scams and flipping the tables to buy it myself at their own price if I think it's nifty.

I built a homemade hot tub system around one of those "ice plunge" bath tubs that seem to be a thing going around these days. They're a rigid inflatable tub, but anyone selling them alongside a chiller sells the tub alone for $500-1000. I found the direct source (Shenzhen Gateo Sports - https://gateo.en.alibaba.com/) and bought one for $200 direct from the factory and love my unbranded tub. ;)

#1 is the website ships globally with no restrictions. A lot of Chinese businesses ship to any country. A local business with their own stock generally won't handle shipping to every single country around the globe. Sure there are exceptions to this rule, but in general it works well as your first sign.

Read the terms and conditions, privacy policy and other more "obscure" information like that. Dropshipping items always ship from China and returns are received to a warehouse in China.

In their Terms of Sale, Sonic Brush mentions that it is rebranding the following product "We are selling the following brand mark : W-White.". So this would be the dropshipping product they buy from AliExpress.

jeffbee 11 hours ago [-]
Why is it now a trend to point this out? Marketing foreign-made inventory in your country is a long-standing legitimate business. Most individuals do not want to personally deal with a Chinese outlet.
tssge 2 hours ago [-]
I think you have misunderstood what dropshipping means.

In dropshipping the business won't have any foreign made inventory and neither will they have any in their country. Instead they will hook you up with a Chinese outlet without telling you.

The Chinese outlet will handle shipping, returns, etc with the dropshipping business just taking a cut for essentially spending money on Facebook Ads. This is the part where you'll deal with a Chinese outlet regardless of your preferences, because the dropshipping company basically did this to you without your knowledge.

They don't have a local stock to replace items under warranty. They don't have a local warehouse to return your item to if you're unsatisfied. They might've never even seen the product themselves and thus cannot even provide support regarding it's use.

So that's why I think it's important to point out dropshipping. It's a completely different thing than keeping a foreign-made inventory. There isn't really any good reason to buy from a dropshipper, because you'll deal with the Chinese outlet behind it regardless.

jeffbee 34 minutes ago [-]

Because it blew up as a get rich quick scheme / "hustle culture" trend recently as it became much more accessible via internet-based dropshipping facilitators, and there's a lot of people trying to make a buck on it, in sometimes nefarious ways.
LoganDark 4 hours ago [-]
Dropshipping is when you order from a merchant and all the merchant does is make an order with your name and address from someplace else. In other words, you could have simply made that second order yourself and saved yourself whatever margin the merchant added on top.

Do note that dropshipping is a very specific term, which does not mean "importing things from another country and then selling them locally", but rather "taking orders from customers and then just ordering a shipment from someone else directly to the customer". For example it would be dropshipping if I made an eBay listing for some product and, whenever someone bought the eBay listing, just ordered the product from Amazon to their address. I never touched or shipped the product; I just made another order posing as the customer.

I've wondered if you could make something to floss multiple teeth at once. Maybe something that fits over a span of teeth such as all the top teeth and is custom fitted so that it fits on the same way each time. It would have holes that you can thread floss through so that when you put it on the floss ends up between the teeth. Then you can pull on the ends of the floss and it flosses between all the teeth that the device is covering.
sarchertech 13 hours ago [-]
You don’t want the floss just moving in and out between the teeth. The point of floss is to scrub the inside face of each tooth. So when the floss is between 2 teeth you want to press it against first one tooth and move it up and down several times and then press it up against the other tooth and do the same thing.

There’s really no way to do that to multiple teeth at once without something much much more complicated.

Dentists are definitely trying. The drills have gotten smaller and gentler, my dentist (and many others) offers a headset so you can listen to music/podcasts while getting your cleaning, and overall they make an effort to be less scoldy and more encouragey.

The process itself is still kind of naturally unpleasant, and the billing sucks, but the people seem to have taken traditional criticisms to heart and made some moves to make it suck less.

There are a lot of fields like this, where they have mostly been reduced to refinements but ultimately are still very barbaric procedures. All we've done is upgrade the stick (in this case, a nice shiny pick), but the procedure hasn't changed much at all.

Too much of dentistry is still stuck on instant fix solutions. Take hard metal, scrape teeth. Something wrong on inside, just drill into it scrape it out and fill it. Dental implants were the last major invention and that was what, in the 60s? There really needs to be far more money and research in the field, because there is ample opportunity for major improvements here as it's lagging so far behind other health fields.

hattmall 10 hours ago [-]
There's huge inertia to change in Dentistry, we know that drilling and filling is basically the worst way to fix teeth. It's firmly established that ART/HVGIC is a much simpler and superior method for 95% of issues. Could be nearly 100% with proper patient education. The ART proponents have been saying this for 30 years, but it's now too hard to deny the superiority. You don't hear Dentist advocating for it though, instead they push fillings, crowns and root canals. Because the majority of a dentist work is actually repairing the inevitable problems that drilling and filling will cause. Drilled teeth will almost certainly need to be refilled and at a larger portion each time.

Loads of studies that show the effectiveness of ART just as well as composites.

And the difference is Novocaine shots and drilling out a tooth vs no numbing need, minimal cleaning with a pick and toothbrush and then essentially placing a ball of putty in the cavity. A ball of putty which actually chemically bonds with the tooth and releases fluoride to rebuild enamel.

But it's hard to charge $350 for something anyone with two fingers can do in about 15 minutes. And then of course if it breaks or comes out the fix isn't drilling an even larger area, it's just filling a smaller hole with putty.

That hasn't stopped other fields. You can get skin patches that utilize micro-needles to inject serum into your pimple, reducing the need to wait for pimples to "naturally" disappear. This was previously thought to be wildly unaffordable. Didn't we just get a new breakthrough for hair regeneration earlier this year using similar techniques?

Fact of the matter is, dentristry has lagged so far behind other fields because there's a lack of care for it. Dental is often not even considered "healthcare", despite how important oral health is to general health. It's also the easiest to hide, who cares about actual rotting teeth just sharpen them down and replace them with plastic. Whereas things like skincare and hair get far more priority due to being visible. Of course there's also the severity, people don't care if their teeth disintigrate, but a broken leg is a broken leg and gets handled appropriately.

munificent 19 hours ago [-]
Maybe it's because dermatology is much less risky since you're talking about a surface level treatment for a very small part of a very large organ. With dentistry, you're going into an orifice that humans must use to survive and directly interacting with the only place in the human body where bone is exposed to the outside environment. The risks are huge. You can die of heart failure if bacteria gets into your gums.

> a broken leg is a broken leg and gets handled appropriately.

Funny that you say that because I'm currently stuck on my couch with a broken ankle, unable to walk for the past two months. I'm very grateful for the quality of care I've gotten, but seeing the X-rays with three metal plates and 18 screws going into my bones sure as heck does look barbaric. But when chunks of bone snapped off and need to be put back in the right place and forcibly held there, maybe that's the best you can do.

This has not been the case in my experience. Dentists have always told me exactly how much I owe them, and the one time I forgot a payment, they called me and texted me to let me know and I resolved it in a matter of minutes.

Meanwhile a hospital visit sent me a bunch of bills in the mail ranging from $50 to $100, they refused to tell me the total sum even when I visited in person, and when I missed one $50 payment I was sent to collections a year later.

Perhaps they were referring to the idea that dental "insurance" doesn't cover more than a set amount which is far under the price of most dental surgeries.

Oh, 100%. Yeah there has for sure been progress. I do also recognize that my anxiety is not just "oh I don't like the dentist", I was lied too. That breaks that trust.

I remember before I found my current dentist, I was having a ton of pain and I tried to find someone. I called them, explained the situation, explained the anxiety and where it was coming from. They reassured me, we have someone who knows how to help with that.

I went there, the dentist came in, I again explained the anxiety and where it came from. This was meant to be a, get comfortable thing. It wasn't a cleaning, just talking. He decides the entire time that he was feeling around my mouth with his fingers, he would hold the scraping tool inches from my face. And then, right at the end to purposefully do a quick little scrape as if, its not big deal see its not that bad.

I just got through telling you I was lied too, that is not the time to do something without telling me that you said you were not going to do to try to convince me that "its not that bad". And then he was like, yeah so we have time if you want to get a cleaning. I have not wanted to get up and leave as quick as I had in that situation in my life, never went back...

That is a rant, sorry about that. But that moment is burned into my brain.

I was so thankful to find my current dentist. When I told them, the dentist called me while I was at home to talk to me in my space that I am comfortable in. Then when I got there I just sat in the chair for a while talking, not laying back, my feet were at the side.

Only slightly related, I have a really bad thing with dental dams, clamps, and anything blocking my mouth - I get really paranoid im going to choke and die - and start overthinking swallowing my saliva and freaking out. Especially taking the moulds for my teeth, it really feels like the back of my throat is getting blocked up by the putty, and they just leave me sitting there with it in.

My dentist would always lie to me saying "just a little longer left" (even when there was about an hour remaining) which really didnt help, and after we finished about 5 teeth worth of treatments she said she "realised" I have 3 more places she wants to do as well..

It sounds hysterical I'm sure, but I dont think she realised that several times per each treatment I'm genuinely convinced I'm about to die - like making peace with god level. I got over myself and was in a really good cycle of going because I wanted to finally fix everything, and then that extra "reveal" of another 2 rounds of treatment just broke me, I couldn't do it.

In the US, dentists and optometrists are separate from our health insurance system, and have their own insurance. Dental insurance usually covers cleaning every six months, and some percentage of the minimum possible correction for things that need work. For example, they may cover 50% of having the tooth pulled but 0% of putting in an implant, because the implant is considered cosmetic and not necessary work.

Anyway, it ends up being like you say, it's a largely out of pocket service that people shop around for.

Honestly... yeah.

As someone who 5 or 6 years ago was not going to the dentist since the very idea of it gave me anxiety after having a particularly bad and damaging dentist experience as a kid. When I would to to the dentist I would have a fight or flight moment just sitting in the chair. (TLDR, I was told they were going to do one thing as a kid, but they purposefully lied to me and did something else thinking I would be less anxious about it happening... yeah that went swimmingly)

The only way I got over that was being able to talk to the Dentist that I was working with, having them explain step by step what they are doing, they check in regularly, etc etc. I finally feel mostly comfortable going, to this specific dentist. The idea of switching has me anxious.

The idea of a robot, while great maybe it could have less human error and all that. No... just, no.

If the thing (or rather the 20th generation of the thing) can be absolutely guaranteed not to cause a disaster in someone's mouth (it should panic on the most minor confusion), and is cheaper than dentists (not hard) it should be made standard.

If somebody needs a dentist to hold their hand, they can go to a fancy clinic that has some sort of doula. But normal people used to get their dentistry done by the same guy who would cut their hair.

Is there really any indication that this will make any change to the cost of dental care? Is the dentists the problem or is it the other parts? There still has to be someone there to manage it.

Also this machine will not be cheap either, will require maintenance, etc. From what I have seen most robot operated medical things, are not to replace jobs but for precision that humans just can't do. Or to reduce human error.

> But normal people used to get their dentistry done by the same guy who would cut their hair.

I would strongly advise against saying "normal" when dental anxiety is very much a thing for many people. I would likely even say most people have some sort of dental anxiety.

There is a reason that a lot of people don't get their regular cleanings, and I am sure cost is part of that but not all of it.

Same here in Japan. I just buy my contact lenses from a shop online; I don't need a prescription at all. The only reason to go to the optometrist is when I feel my lenses are no longer the correct prescription (since your eyes change over time).

And for the eye-health tests that eye doctors try to use to justify yearly visits, that's done for free at the annual health check that everyone gets. Unlike the US with its weird system that considers eyes and teeth to not be necessary for health, those are all covered by the same single health insurance that you normally get, either through your employer or from the government.

Lets not lump in nurse practitioners. I'm absolutely in favor of giving more responsibilities to NPs and paying them more than they currently are.

Data on doctor salaries is very difficult to come by publicly, however H1B salaries indicate the average pay for H1B PCPs is $200k [0]. These are the lowest paid physicians. If you look at the data, many many physicians are making much more than that - with many specialities averaging $300k+. Generally H1B workers make less than comparable native-born (even though that's illegal) so we should view this as a lower-bound.

That puts hourly pay for average PCPs lower than the top SWEs, but comparing average with average or specialty with average and you're already quickly outpacing large majority of SWEs.

In a nutshell, no amount of lobbying will stop equivalent service for 100x cheaper. Tech does not permeate healthcare for 2 reasons: 1. mostly inapplicable. Everyone is focusing on ML model performance, but really information retrieval in healthcare is dismal and prevents the use of such new tech altogether except in very niche cases. 2. no integration in the workplace. Tech people and docs don't understand each other at all, so docs ask for impossible things, and tech people deliver perfectly functional, totally inapplicable tech.

If there are algos out there (and there are) that can accurately provide a strong heuristic on melanoma from a photo and this is being blocked by the state - that seems like an obvious instance of regulatory apparatus stopping an equivalent 100x+ cheaper service.

I've discussed with a number of people who work directly on DL for imaging at a major hospital system in Boston. They say that (outside of the doctors they work directly with) fear over competition and losing out on the pricier billings are one of the largest barriers to getting their (very accurate) tech deployed more widely.

Yes, so as usual it's so superior but it's never used. And the people building it say it's stellar, promise!

whimsicalism 22 hours ago [-]
You can find the studies on the recent melanoma classifiers. There are tons showing in various settings that they pretty clearly outperform physicians.

If 'additional mouse clicks' is a major barrier to physicians using a tool that leads to far better diagnosis outcomes of a fast-progressing and deadly disease, I'm not sure why that is an argument for why things should continue to be as physician-gated as they are.

I will happily perform the 30 extra clicks myself if it is my potential melanoma. But if I were to offer it as a self-serve app ($2 for melanoma diagnoses too cheap to meter), I would be thrown in jail.

All countries control rather strictly who can practice medicine. Yes, there is some amount of protectionism, but that happens almost everywhere.

Access to care is a complex problem, and IMO not primarily limited by doc counts in the US.

Young docs would absolutely work less for less if possible, I think. Old docs wouldn't. IMO, that's reflected in the rise of big network providers such as Kaiser and friends.

In Europe, access to care is better IMO mainly because both patients and docs are far less aggressive, and often quite happy just doing nothing. Which is in fact the true problem about US healthcare: the culture of absolutism.

There is always a strong sense of national pride in medicine. Many people both inside and outside healthcare believe their nation has the best care, and make it an institution of sorts. It really seems stupid and insignificant, but the fact that foreigners are not feeling welcome has consequences. For example, US people often compare to german docs. Except I'm from Europe and having worked in the US, I can tell you I wouldn't go back to the US even for a million bucks. Why go somewhere you do 1.5x the hours, have a miserable quality of life and be treated like s##t, just to earn a little more ? So, if the US was to open the floodgates to foreign grads, I don't think the 'brain drain' would go the way people expect.

Within the US, the limitation of admission of US students into med school is another matter. And I think people are probably right to call out protectionism in this case. But I have no first hand experience, being a foreign graduate myself.

I'm just a random bloke having worked in Boston, though. So YMMV.

100%. The US/Can approach also limits/compresses the potential career length. Make it ~6 years and out, straight from high school (if you so please). It kinda works like this already in Quebec: you can enter medical school straight out of CEGEP.

It's also a meritocratic matter: you have to take a lot of risk to make a go for medical school, and the best candidates may not be able to afford the risk of failing to achieve their med school goal and ending up with a degree with ??? value, so the best may not take that path.

Or worse, taking an easier degree program (to beef up their grades and have time for other application-enhancing activities) and not getting themselves educated to their full potential.

It is possible. Lots of doctors work fractionally. It's one of the easiest fields to do it in. Given the artificial shortage, hospitals essentially have to accept it.

The reality is many doctors are simply driven people. They don't really mind the hours, but they do mind the type of work. A lot of it is just terribly unfun.

Physician salaries are less than 10% the cost of healthcare. You could eliminate their salary entirely and it'd have no meaningful difference on the cost of healthcare. There is _absolutely_ an artificial supply limitation, but that's increasingly being worked around by the use of PA and NP providers. Doctors essentially become managers for PA and NPs.

My wife is a physician. Actual, scientific diagnosis is a ridiculously small part of her job.

Most of her time is taken up on "soft problems". Writing notes for continuity/quality of care. Justifying medical decisions for billing purposes. Advocating with insurance and healthcare administrators. Discussing treatment plans and options with patients. More notes. Well, really, most of her time is taken up with notes. It's really the only way for her to capture all of the soft variables.

Writing notes is a bit like coding. LLM/AI can help solve the problem, but ultimately you still need to go through them piece-by-piece to ensure they're correct.

Notes are kind of a poor term for what these documents actually are. To the lay person, notes are what you take during a meeting or lecture. A sort a annotation of what happened. Notes in medicine are essentially a treatment plan that includes justification and context for that treatment plan. It's essentially the physician's thinking on how they're treating a patient.

A lot of patient care centered specialties (as opposed to surgery or technical specialties, like radiology) are seeing a shift towards NP and PAs. The physician will be legally responsible for the actions of one or more NPs. They'll review their work and ensure their plans are correct.

Unlike the other comment defending current medical practice, this one I absolutely agree with. I do not think that physician salaries are the major drivers of healthcare cost. I do think that occupational licensing reform would help bring down cost, but agree it is only a relatively small factor.

However I do think that in the process of engaging in wage protectionism (and there is absolutely no question that doctors do this) there is a ton of consumer surplus that is being lost and not captured by either patient or provider. For instance, in the case of the melanoma AI, that is a casualty of the wage protectionism (+ medical conservatism + FDA failure) - the value there isn't being captured by doctors, it is just disappearing into thin air and tons more people will just have undiagnosed melanomas.

SkyPuncher 15 hours ago [-]

I actually think this is the only way to bring costs down. Most providers, equals more competition. More competition leads to innovation and all around better outcomes.

Interestingly, a lot of states are starting to express their frustration with physician supply shortages by expanding rights for NPs and PAs. I think over the next 20 years, we're going to see MD/DO roles transition to largely supervisory roles with NPs and PAs doing most of the work. Much more akin to manager/IC type of roles we see in STEM type fields.

A freshly-minted dermatologist isn't making that much, though they will be in the long term. As a whole, physicians aren't very organized to deal with these types of technological "invaders." The AMA and similar organizations' core competencies have traditionally been limiting supply and creating personnel exclusivity (limiting residency slots, limiting the usefulness of foreign-obtained credentials, etc.)

I promise you can find an endless supply of freshly-minted dermatologists who will sign off on these ML-identified melanomas, bypassing the old guard with their rubber stamp. Once the tech is proven, that rubber stamp is worth nothing and may be removed.

For example, see [1] where a general surgeon made an average of $118,689 in 1984 and a family practitioner $84,256. This would be $358k and $254k in 2024 dollars. Today in 2024 they make on average $423k and $272k respectively [2].

Nursing care added another 4.3%, and other personal health care expenditures (dental, medical equipment, and other professional services) added another 16.5%, or about 2/3 of total costs when all taken together.

By the way, an average salary of $423K is pretty good, and a six month wait to see a specialist amounts to denial of medical care. Serious reform is needed.

All the rest of the logic you supplied yourself.

Since you seem intent on sticking words in my mouth, I don’t think doctor are necessarily paid too much, and don’t think limiting their salaries will substantially affect health care costs. I do think doctor salaries probably will go down if their ranks weren’t artificially limited, but society would benefit, and doctors might too with a reduced workload. In fact, the overall proportion of medical costs given to physician salaries will likely go up if their ranks weren’t limited, albeit with each individual doctor making less.

SO is a dentist. They laughed and said 90% detection leaves a lot to be desired, and there's rarely a good reason to not have an X-ray.*

In addition, there's some things a human dentist does that I doubt this does - early detection of oral or skin cancer on the face being one of them. If you have the same dentist you'd be amazed at what they remember about your face and what's different from last time.

General vibe is that even if it can technically do a drill 'n' fill, it has a long way to go before it can substitute for a trained medical professional.

* Edit: I'm actually going to go further and say that calling an X-ray "harmful" should constitute disinformation and therefore wariness towards the attitude or motive of the author, since it's patently not true. The fraction they use at the dentist's isn't going to hurt anyone. The comparison point I've heard (and can't personally verify) is 6 dental X-rays is equivalent to 1 trans-Atlantic flight; alternatively 1 x-ray to a weekend in Cornwall.

I'm sure this can happen, but that's different to every dentist doing it. And a dentist doing harder to automate stuff while the 15 minutes go on instead of 2 hours means way more patients treated in the same time period, which means costs can hopefully come way down for some dentistry.

It's definitely what I'd like to see for the future, in the same way that calculators improved the capability and throughput of professional mathematicians; as a tool that assists to enhance and augment delivery of a service.

CNC milling already exists for crown prep. The drilling of the tooth itself is not a long operation. The reason that a crown is split into 2 sessions is (depending on your local health board's practice guide) to ensure that the tooth is still viable for a crown; bleeding to stop, inflammation to go down.

This revolutionises nothing... But it is a step towards a revolution. It can only be a good thing. However, in the same way that there's technically a lab-grown hamburger out there, it's not going to be commonplace for a while.

I'd much rather have a 90% detection rate without an X-ray than 100% with. Destists are very trigger-happy with X-rays, in part because of the extra billing, but mostly because it makes their job easier and prevents mistakes.

The estimates of the hidden costs of radiation risk are tentative at best. Some people have inherently higher risk and many are not aware of it. Either way, it can take years or decades before the effect plays out. By then, no one is going to implicate the original providers who pushed for an elective X-ray.

Also, note that not all ionizing radiation is alike. The exact spectra are different and the exposure intervals are very different, so the comparisons to environmental sources don't necessarily hold.

sierra1011 18 hours ago [-]
Absolutely correct, and my examples given are unsubstantiated and anecdotal at best; I'm not in the medical physics field.

Honestly, I'd take both. If standard light imaging is 99% efficient then it adds additional triage and diagnostic capability.

As regards the billing situation, that may partially be a locale issue rather than an all-dentists thing, but even within the UK it's disappointingly nonstandard and subject to manipulation by the dentist.

Despite all that, you say that X-rays are pushed because it "prevents mistakes". And my response would be along the lines of "well... yeah..." because a mistake turns a simple filling into a more complex (and expensive) operation that could cost a tooth and £x,000.

Speaking from personal experience, if the dentist wasn't concerned about anything on my teeth and I didn't ask for an x-ray, I didn't get one.

I keep seeing this template response/attitude but I think it’s generally flawed. Here’s why.

You judge a prototype / instance of a technological field that’s otherwise in full swing, cranking on releasing next version long before you see the current one

You assume this will be isolated from the rest of advancements, but in reality once you have the mechanics to automate imagery and drilling 100x more technologies can be composed. Memory in particular is something tech has always surpassed humans.

The combination of these two, particularly in the context of AI is much faster than most people can perceive.

So saying yes but x, is irrelevant for the most part.

sierra1011 18 hours ago [-]
A reasonable take, but one that I don't think lessens my point.

I can't speak to the other responses from which you've identified this yes-but-x template, and can speak really only from the 2 bits of knowledge I have: IT/infrastructure stuff is my primary knowledge, and my SO's dental training and practice, which is not "my" knowledge, but from this I have access to more knowledge than would the average person.

Now, the IT stuff. Automation has come a long way and quickly, but if I break something, it's just a service. Worst case scenario a customer can't buy something, or maybe a couple thousand customers can't. Big deal, one a minute, etc. I don't need to preach on this, I'm sure.

The medical field is significantly slower to adopt new practices, with the reasoning that their customers' custom is not an item in a cart, it's their health or life. New technology comes in slowly, with trials for wide population application taking decades in some cases. The stakes are so much higher that safety demands caution.

This does not of course mean never. I've said this in another reply also, but I think tooling like this augments service delivery at the very least (provided it meets safety standards) and could be the start of a boom of up-tooling practitioners. And I will be surprised if I see one in the flesh before 2050.

I think what's being overlooked here by some commenters is the speed of this machine.

A normal cavity filling can take 20/30 minutes. Imagine if that could be cut down to 1 minute with a perfect filling at the end? Even if we are talking about the dentist messing up the pain killing application it'll all be over pretty damn fast.

Agreed.

The freezing doesn't always work for me. If I say "hey, I can feel that" the second dose might work, and it might not.

What happens next is that they slow down, and while this sounds like compassion, it also lengthens the time they're drilling into my head while I can feel it.

Just building up a resistance to physical torture. Bring it on, movie CIA guy.

I think a quick, very intense filling might be better than a long, slow one.

I may be weird about this, but for me when I've been drilled (or even cleaned) and experienced tooth pain the level is 100%. I can't feel more pain.

I'm certainly not advocating that dentists don't do their best to numb patients before drilling. What I'm saying is it's fairly likely that by the time they can stop the machine in the case of pain the procedure will be nearly complete and the pain over.

Pfft. That’s nothing. Imagine if it was 30 seconds rather than twice that time? Can’t get better than that.
cogman10 20 hours ago [-]
The actual drilling can be quiet fast. The limiting factor is making sure it isn't so fast that it shatters the tooth. What will take time is bonding the filling.

My assumption is that for a regular cavity fill, the drilling will be a much smaller portion of the time than the filling bonding. You can see that in the crown placement video in the article, almost no time is spent removing the outside tooth. The actual spent time is building up the crown.

I’m simply too old and seen too many BSOD to ever allow this to be done on me. Also I just watched the Fallout episode with the Mr. Handy in it. The picture in the article of the robot hand moving a drill into his mouth fills me with intense dread. Maybe the younger generation would feel differently. I didn’t let my Tesla drive either.

> I didn’t let my Tesla drive either.

I know how bad humans are at driving. I don't have a Tesla, so I don't know if I'd let one drive, but they only need to be better than humans not perfect. I just wish there was some unbiased source of data as to how good they are - the only numbers I can find come from those who have reason to lie (mostly Tesla, but other self driving car companies as well).

There are rules around how medical software is developed and so if this is property approved by the FDA or equivalent I'm not worried - it may not be perfect, but human dentists are not either.

My experience with the recent tesla supervised-but-still-full self drive beta was largely positive. I have a cameras only Y with hw4. I think John Carmack will win his bet. I do think they need regional model modifications though. The way you drive in different places is different. In some places you can't signal that you want to change lanes or people close ranks. In others people make room. It did two stops at each stop sign in places that had no crosswalks, picking some arbitrary distance before the intersection to watch for pedestrians, then it pulled up to look for road traffic. Perhaps not a horrible idea, but humans around here don't do that so it confuses other drivers and pedestrians both.

You must not have any experience working with medical software.

This is lawyers checking boxes, nothing more. The people that actually wrote the software likely are outside the jurisdiction of the FDA and have zero incentive to treat the software any different than any other hastily organized project. After all, why would any of these people care beyond their paycheck -- it's extremely foolish to assume others hold the same priorities and values as you do.

It only has to screw up and inflict harm at a lower rate than a human. Human dentists injure patients every day.

I don't think "lower" is enough. Human psychology requires "much much lower".

At least this is actual CNC software using math and geometry that somebody can find the bugs in. What terrifies me is “software” that is really just black boxes filled with floating point numbers and no one knows how it works, or when it won’t.

IDK. Logically you are right, but humans are emotional.

Just a day or so ago, here on HN, full of IT guys, there was a discussion about some Tesla autopilot crash. People were absolutely livid and demanded the impossible. Now - generic Musk hate might have something to do with it, but I suspect that it is not just Musk. We really react very unfavorably to machines wreaking havoc, while our tolerance for humans fessing up is somewhat higher.

Because we feel better when those humans can go to jail as a form of Justice since now that person gets to suffer in exchange for the suffering caused.

Meanwhile we don't feel anything if the robot that killed someone gets decommissioned because machines Don't suffer.

Yup.

Over 100 people die in car crashes in the USA every day. When a fatal car crash happens, it MIGHT make it to the local news. But a single car crashes while driving autonomously and it's national news for MONTHS.

Now, I'll acknowledge that there will be statistical bias here. There percentage of cars driving autonomously at any given moment is likely less than 1%. But autonomous cars make different kinds of mistakes. They'll fail to identify the lines in the road correctly, or fail to recognize an obstacle. Meanwhile, humans will drive drunk, drive distracted, or have massive egos and drive dangerously because they think they own the road and everyone else is just in their way, or just simply be bad drivers that don't even look around themselves before changing lanes.

But you're letting your device auto update even though you might come from a period where you had to voluntarily and manually install a service pack or start manually your internet session by dialing up your provider... Like I did.

I even remember manually mowing my parent's lawn when I was a teenager while there are now many mowing robots that wander around with several spinning blades.

And what about having 2 tons Waymo's car wandering around without a driver?

Are we getting too old for this shit?

Have you switched dentists recently? I have little trust in the profession (though I like my current dentist).

Around 2008 every time I went in to the dentist she found cavities. I moved states between a bad diagnosis and getting any fillings and when I went to a new dentist I came out with a clean bill of health.

I moved back and had a dentist that I trusted, she sold the practice and the new dentist started finding cavities every single visit. I switched dentists and magically those cavities were gone.

Not only did I likely get drilled and filled superfluously, the first dentists fillings fell out or broke and needed to be replaced after a few years.

If a machine was doing the work, economies of scale also create a large enough class that if the treatment is not effective the class can sue. Against a one-off terrible dentist with a small sample size, the chance of compensation for terrible work is almost non-existent.

Last time I went to see my US dentist, he said I needed another filling. I wasn't feeling it for some reason, I told him not now, and he looked at it again, and said "I agree". Now I sort of regret getting my other "small" fillings.

I've had a dentist in Europe who laughed and said there's no need to come here every year, that's an American thing.

avgDev 23 hours ago [-]
In the end dentist offices are businesses, and often dentists have small practices.

I've recently listened to a podcast of a dentist turning consultant to increase numbers. Dude literally applied a lot of marketing tricks, tested them and analyzed the results. He did things like naming teeth cleaning, a "clinical teeth cleaning" or something along those lines. This resulted in an increase in cleanings. I guess he could be lying as he is now selling his services but the whole podcast felt disgusting.

Does not even need AI. Simple algo: default: filling If too much filling: crown If crown failed: pull

For each step don't forget to collect the cash.
