In Word 2003 you can protect the styles; before that, no. A couple of ideas:
Make sure that the styles don't have 'automatically update' set - if they
do, any direct formatting the user applies will change the style.
Give users a menu or toolbar to apply styles with - then if they reapply a
style to a paragraph that has some direct formatting they won't get asked if
they want to redefine the style.
You might also want to look at updating styles from template. You can do
this with a one line macro (ActiveDocument.UpdateStyles) that could be run
to 'clean up' documents or manually from Tools > Templates and Add-ins (but
if you do it this way you should uncheck the option afterwards).
Hope this helps

Thanks!
I thought the answer was no for Word prior to 2003, but
wanted to make sure. I did not think of the other
possibilities you mentioned, and am glad you suggested
them.
