Dr. David Clark will explore his tumultuous journey that occurred over two decades as he battled to reconcile Microscope Enhanced Dentistry with Patient Centered Outcomes. Attendees will receive updates in endodontic, prosthetic and direct restorative techniques that challenge currently accepted dogmas.


Attendees will learn:

  • The 5 plateaus that they may experience over their microscope centered practice lifetime
  • Modern Injection Molded, monolithic composite dentistry that is finally challenging indirect (ceramic) restorations
  • Deep Margin Acquisition for Class II composites for previously untreatable deep caries
  • Treating the Dreaded Black Triangle
  • The Frustum (vertical margin) Crown Preparation for compromised teeth, and possibly all crowns
  • Minimally Invasive Endodontics today: Lip service and marketing or actual progress?

Dr. Clark is co-director of Bioclear Learning Centers International. He founded the Academy of Microscope Enhanced Dentistry. He is a course director at the Newport Coast Oral Facial Institute. He is on the editorial board for several journals and has lectured in 20 different countries.

Dr. Clark's interests include the re-designing of restorative and endodontic cavity preparations; an overhaul of the tragically outdated GV Black cavity shapes. For composite dentistry, this includes the non-retentive Class II preparation which requires the Injection Molding Filling Technique, and Injection Over-Molding of worn, misshapen and fractured anterior teeth with the Bioclear 360 veneer technique and system.

Dr. Clark has developed the Bioclear Matrix System that promises a real advancement for placement of biologically appropriate, esthetically pleasing direct composite restorations for treating minimally invasive Class II preparations, diastema closure, and black triangle elimination combined with papilla regeneration, and traditional anterior composites. He has been granted several US patents.

He and Dr. John Khademi are widely acknowledged as the fathers of Minimally Invasive Endodontics, which at first was rejected by most North American endodontists, but is now being embraced by the mainstream. Dr. Clark published the first guide and classification system for dentin and enamel cracks based on 16 power magnification and has conducted studies on cracked teeth. He has designed numerous instruments, burs, wedges, matrices, separators and equipment and has written chapters for both esthetic dentistry and endodontic textbooks.

Dr. Clark served for 18 months as the lecturer and lead dentist for CRA during Gordon Christensen's absence and served on CRA's board of directors for several years. He maintains a private practice in Tacoma, WA, USA.
