Dental exarticulation
Abstract:
Tooth exarticulation or avulsion refers to the complete displacement of the tooth out of its socket. It is a complex injury, requiring immediate intervention for optimal results. Literature indicates that prolonged dry time and improper handling may be associated with increased risk of failure. Immediate replantation of the tooth allows for immediate restoration of esthetics and phonetics. This case report presents the management of an avulsed mature tooth in a young boy, with a two-year follow-up, which had been preserved in milk after around 15-20 minutes of injury and transplanted after two hours at a dental hospital. Timely modified endodontic therapy prevented subsequent inflammatory root resorption.
