Dr. David Clark is a pioneer of sorts. He started using a dental operating microscope long before they were "a thing" for restorative dentists. Once he started routinely using a microscope, he realized that how we handled composite resin needed improvement. So he set about to change the way dentistry understands and uses composite resin. In the first half of our fascinating talk with Dr. Clark we talk about:

dental operating microscopes, why and how
selective caries removal and the "Modified Hall Technique"
why mylar is isn't just wrong, but "fractally" wrong
the development of Biolclear matrices and the Bioclear Method

Also helping us with our interview is Dental Hacks regular Dr. Arthur Volker who is also an instructor with Bioclear.
In our Brain Trust segment we take an entertaining look at the onlay vs. crown debate. Dr. Arthur Volker, Dr. Lance Timmerman and Brain Trust newbie Dr. Will Wyatt discuss the how and why of tooth preparation and materials selection. You'll hear about:

onlays vs. crowns
the minimally invasive "mullet" prep ("all business on top and a party in the back") for lower second molars
vertiprep dentistry, aka: minimal prep at the margin using full contour zirconia (vertiprep anterior cases courtesy of Dr. Jason Smithson and Dr. Carlo Poggio)
provisionalization
Dr. Timmerman's material choices for shrink wrapping temps (J. Morita's Blue Velvet and Flexi Velvet for making a provisional matrix)
