- zihotki 3y agoYou usually don't visit dentist each week or two so the damage you'll receive there can be ignored.
- neals 3y agoAny damage can be ignored.
- data_maan 3y agoIsn't DNA damage lifetime accumulated? (Unrelated to the first) Even if the probability is low, say 0.0001, of DNA damage happening after a single dentist visit, that still will result in hundreds or thousands of cases of DNA if the population is large enough, i.e. in every larger city.

- dekhn 3y agoDepends where the damage is. Skin is made mostly of epithelial cells with a limited lifespan. Genetic damage to individual cells isn't lifetime- it goes away when the cell dies. The damage a damaged cell can do is significant, though. But those cells are grown from stem cells, and if they remain undamaged, their descendants (the brand-new epithelial cells making up skin) will begin their life already damaged. With all that said, the underlying biology of cancer is extremely complicated and it's hard to evaluate the impact of things like this. Some amount of DNA damage happens constantly that bodies can clear up without any real long-term impact. For a dentist visit, we assume that the increased benefits from infrequent x-rays exceed the low probability of cancer. I don't know about UV used in dental applications, though.

- thomasreggi 3y agoI've gotten a couple gel manicures recently, it's addicting once you start because it lasts a long time. I'm taking a break from it because it makes your nails brittle. They make special gloves you can wear that just expose your nails, ideally I was thinking the same technology in 3d projection mapping could be used to only expose the nailbed to uv ligt with hand tracking. It would increase the the cost of one of these uv curing devices by smartifying it but would prevent cancer...
- p1mrx 3y agoFlipping through https://www.google.com/search?q=photoinitiator+absorption+spectrum&tbm=isch https://www.google.com/search?q=photoinitiator+absorption+sp... suggests that some photoinitiators work with 222nm UVC light. That wavelength is currently undergoing safety testing for killing germs. Maybe that's a possible alternative? Penetration depth might be an issue, since that's what (supposedly) makes it safe for skin.
