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