Dentistry has changed in the last decades. If a dentist refuses to use useful computer things, I instantly wonder if they are also out of date with modern best practices. Better materials for infills and stuff like that.
Wouldn't surprise me if they went fully robotic for some things in the not too distant future.
I'm impressed they only got the bedside one recently. My dentist just recently upgraded to direct digital sensors for their x-rays (wires to the computer in the room instead of digital plates), but the X-ray source shows decades of battle scars.
My mother is a dentist on the verge of retirement who used to fly to conferences all the time and ran a reasonably successful dental practice with about a dozen employees (and plenty of computers). She would always talk about how the new implant ceramics are not as durable as the old amalgam and they're only popular because they're white instead of gray.
