Treatment of a Case of Complete Avulsion with Complex Crown-Root Fracture in a Young Permanent Tooth
Abstract：Tooth trauma is commonly seen in children and adolescents. According to the Andreasen classification, dental trauma is divided into four categories: injury to hard tissues and pulp tissue, periodontal tissue injury, injury to supporting bone, and injury to gingiva or oral mucosa [1]. Complete avulsion is the most severe and special type of periodontal tissue injury, while complex crown-root fracture is one of the most severe types of injury to hard tissues and pulp tissue [1-2]. When two different types of trauma occur simultaneously on the same tooth, they can influence each other and lead to more serious consequences [1-2], which also presents a challenge and difficulty for clinical physicians.
