This document discusses different types of traumatic dental injuries including concussions, luxations, fractures, and root fractures. It provides details on clinical signs, radiographic findings, treatment objectives, and treatment plans for each type of injury. Concussions involve inflammation of the periodontal ligament without tooth displacement. Luxations occur when a tooth is displaced from its socket, often tearing the periodontal ligament. Fractures can be confined to enamel, extend into dentin, or expose the dental pulp. Root fractures occur below the gumline. Treatment aims to relieve pain, reposition displaced teeth, and restore tooth structure depending on the specific injury.
