yes, please do a search, and you are excused from doing so since you barely had 0+ posts. I suggest you to visit SDN a lot, and do bunch of searches. It will be significantly helpful in your dental applications.
I can almost assure you that any question you've ever had about dental application was also on others mind, and there are bound to be plentiful of posts on any questions you have. Good luck, and welcome to SDN. It's a wonderful experience!
