The New Science of Strong Teeth: This is a Core CE seminar

The Epidemic of Cracked Teeth, Diagnosis, Treatment & Prevention
April 28, 2022
8:30 am – 4:30 pm
  • David Clark, D.D.S.
  • Alex Fok

Currently the diagnosis and treatment of cracked and fractured teeth is largely symptom-based, and is therefore an end stage diagnosis. The fracturing process is one of dentistry’s last great mysteries and is poorly understood throughout the generalist and specialist dental community. In this engaging lecture, you will learn to understand and diagnose pathologic cracks utilizing magnification and other modalities, and treat long before symptoms arise or the tooth becomes unsalvageable. Dr. Clark will teach routine identification of early cracks. You will learn the Clark Class II saucer shaped nonretentive preparation and Fissurotomy Class I that are a significant departure from the G.V. Black preparations that are a leading cause of cracked teeth.

Learning Objectives:
1) Have confidence identifying early tooth fracturing based on high level magnification.
2) Learn why new Class I and Class II cavity preparations with new bur shapes are crucial to prevent eventual tooth fracture.
3) Receive a blueprint for diagnosis and treatment of fractures and incomplete fractures.
4) Understand the Fissurotomy, Calla Lily, and Overlay preparations for Class I restorations.
