Is dental treatment included under medical insurance in any countries outside the US?

I'm looking to find how it works in other coutries...does the medical insurance ever cover dental care?
--------------------
I can tell you about the medical system in Germany: yes, the basic dental therapy is covered by the medical insurance. You don´t have to pay for check up, x-rays, root canal treatment, extractions, periodontal treatment, tartar removal (once a year)...if you want something special, like a composite filling, any better type of crowns (not just gold) then you have to pay. The price you pay depends on how much you earn. When you´re poor, the insurance pays more, sometimes even everything. But you´ll just get the cheapest materials. Our system seems to be much better than yours, but still it isn´t perfect and we have a lot of trouble. When I first read all the questions here, one thing really striked me: many people don´t have any insurance!!! In Germany you MUST have one. As soon as you have work, you´re automatically getting insured by your boss. If you´re jobless the work-agency pays your insurance.
