Do you have advice that you've heard that you use on almost every single procedure? I do. And it came from today's guest, Dr. John Burgess. Dr. Burgess is the assistant Dean for Clinical Research at the University of Alabama at Birmingham as well as Director of the Graduate Biomaterials Program and was recently featured on the main stage at the Spear Summit 2022.  But I heard John at the Spring Vedder society meeting some years back and some of the things he said have stayed with me to this day. It was a true pleasure to get to talk with John about what he does, how materials research should be done and how dentists can be better at understanding materials. How does someone get in to biomaterials research? Clinical research at LSU How to find unbiased information...how do we evaluate literature? Is the research measuring what they think it's measuring? Bevels on posterior composites? How do we test this? (spoiler alert: don't bevel occlusal margins) The best material is "abuse tolerant." How do patients get screened for clinical research? NCCLs (noncarious cervical lesions) and the controversy surrounding them New chemistry Read the instructions more often than you think you should! "Dentists don't read" Manufacturers take their instructions very seriously...you should, too.
