failbeta Out there and so a lot of us are still practicing the same way that we didn't dental school and from for younger Dennis that's okay because you know it or it's okay to a certain extent because we were. In dental school so recently that a lot of the science hasn't changed much but from for some of the more mature and an older dentist they're still doing things a certain way know. That they were taught 1520 years ago and now you think may be completely different and in the science world so you think it is that it's definitely a challenge to keep up with the science and in it sort. Of seems like okay will now miss our practice EBD is now have to change the way that I do everything under the under the sun dentistry wise and that's kind of untrue. I mean that the corporate evidence-based introduction have any deal the way I did my office is is basically that when something comes up that I don't know about where I want to check. On and look at what the sign says I go to the pub med website and search for journal articles is basically what it comes down to the ADA also has it as a evidence-based dentistry website.
