A Road to Managing Dental Trauma with Predictable Results

Published on

Dental trauma can range from minor enamel injuries to significant loss of teeth and hard and soft tissues. When faced with such emergencies, the clinician must consider
surgical, restorative, endodontic, and periodontal implications and make quick decisions on a treatment that can lead to the best long term result. In this presentation,
Dr. H. Ryan Kazemi will review various types of dental injuries and a simplified map to choosing the most appropriate treatment quickly and easily. In addition, he will discuss complicating factors and treatment concepts.
