    I've been toying with the idea (if not the reality) of getting an
operating microscope.  The cost however is a big turnoff, esp. since
(despite the articles from restorative dentists using them) I have my
doubts about just how much I would use it.
    I started idly looking around to see if I could get some reasonable
semblance of an operating microscope on the cheap, and saw a guy on ebay
selling a lot of instruments like this:

    Is there any reason why something like this couldn't be made to work?
I e-mailed the seller who said that while this wasn't what it was
designed to do, he knew that a few folks were using it as an operating
scope.
    I kinda wish Glen Van As was still here--he was the micro guy.

This doesn't look bad, though I also have my doubts about how much I
would actually use an operating microscope. I wonder what I could
actually accomplish clinically that isn't being accomplished already.

One factor to consider is the depth of field. It would be very annoying
to have the top of a prep in focus but the bottom out of focus if the
depth of field isn't very great.

And patients move around, too. Their movements would be magnified.

    Good points.  I think some of the microscopes marketed for dentistry
have greater working distance--I think this one is up to 200 mm--don't
see if that's at all magnifications.
    Despite the restorative dentists who use this to look at their margins,
I still think I would find most use for this in endo.
    Of course, the hook is that I like toys.

I would buy  a surgical microscope tomorrow if I could figure out
where to put it  in my crowded operatory.

I would be concerned about disinfection & splashing on the lens. I bet
if does not last well exposed to our chemicals.

    Do you think those intended for dental use are somehow shielded?
Obviously the optics don't come into patient contact.  I assume the body
of the microscope is covered with some kind of disposable sleeve.

Stream-lined, surfaces designed for disinfection, and proper optically
designed shields. Plus, Many are set-up for the DA to look through a
so of lenses while you use yours.   Also, you would want a video
output on it

Funny.... when I go sometimes to the Local Endo Guy's place for courses
or whatever, his 'scope is always packed neatly over against the wall.
It never seems to get used...

Re: disinfection: You could always fix a microscope slide over the lens
and then clean _that_ instead of putting disinfectant on the lens. The
controls could be covered with plastic sheaths like you put on your
overhead light source handles, or your air/water syringe.

Don't know about depth of field.

I would use one to find fourth canals in Endo and to inspect margins on
a crown or in/onlay prep. I don't think I'd use it for more than
specific instances like that.

.... Or maybe if there's a hot chick on the chair and I want to impress
her...

..... Or maybe if it's the MIL on the chair and I want to DIS-impress
her, I could find fault with every tooth in her head...

I forget the term, but the working distance. (is it focal length?) You want it
at the right length to see and sit comfortably while working.
