Hi, I was hoping someone could answer a few questions for me. I know that for medicine one must write the USMLE once in med school, what is the test that you have to write in dental school? How many steps are there? When do you write each step? Also, is this a national test, ie. can you work anywhere after having written it? or is it a regional thing(does each state have its own or are their regions)? If it is regional does it matter what school one attends? Also, how long is the residency period after the 4 years of dental school? I know these are a lot of questions, but I think they are fairly basic, and hope that someone can answer some or all of these. Thanks.
