I think it depends on how often the dentist updates the office equipment. I'm sure that stuff isn't expensive and why upgrade when what you have works?
I've gone to dentists in totally new buildings and saw some things I didn't see at my old dentist who had been there for years.
You also have to factor in familiarity, ie does it make sense for a dentist to pick up a new tool with slightly better outcomes if they’re going to make more mistakes while they learn on it?
