Here's my point of view, as a practicing dentist. (How many dentists do we have in the crowd here anyways?)
A large part of my judgement between decayed versus solid tooth is via feeling, whether it be with the handpiece when drilling, or with other instruments. Color isn't reliable, as decayed dentin can often be normal coloured, and solid tooth may well be stained. There are various dyes available, though from the last few studies that I remember reading about, they often stain more than just decayed structure, which of course means you'd end up removing more tooth. Once could cut with the laser and check with another instrument, but the touching of the dentin would probably be quite unconfortable.
Tactile sense is nice to have as a guide when working as well, besides for distinguishing between decay/non-decay. Push harder, and you feel resistance. Move to a point where you're no longer touching the tooth, and you'll feel open air. One would have to learn to adjust to not having that feedback when using a laser, but that wouldn't be too difficult.
The only laser I've used personally in my pratice is a device known as the DiagnoDENT (manufactured by KaVo, a German company), which measures fluorescence from the tooth as excited by a HeNe laser (IIRC) to detect decay (since decayed tooth structure gives off greater fluorescence). It seems to work fairly well for very shallow cavities, but for anything deeper, I personally found it less accurate than I would have liked. Hence, I don't use it much these days.
Other uses of lasers have included soft tissue surgery (of course), and curing lights (I think there have been some problems with the narrow spectrum of lasers and some materials using different photoinitiators... also a concern with the more recent LED curing lights). I haven't used any of these personally. Equipment tends to be... expensive.
BTW, for everyone who keeps on saying 'Novocaine'... Novocaine hasn't been in use for a long time now since too many people had allergic reactions to it.
Ancient Art of War was released in 1984, so it predates even Herzog Zwei. I remember playing it on the PC, though it was released for a number of different platforms.
While by default the battles would zoom in, there was an option to not have control over the battles.
It had a map editor so one could make custom maps, supply lines to your troops which affected their fighting ability... it's been too long, I can't remember most of it too well, other than too much time spent playing it.:)

That would be 'Stones', probably the song most associated with the Ultima series. Probably my favourite song from the series as well.
Too bad from U7 onwards it's missing its last verse.
Some Ultima fans may argue it's overplayed though...
While Quake 1 was developed on NEXT, the target platform at that time would have been DOS, so multithreading would be a bit of a problem...
As to further licencees of the engine, revamping the engine to use multithreading was probably not a very high priority in making a game.
On the other hand, for someone writing an engine from scratch is a different matter.
Wow, it's been a while since I've made a post.
