Trauma as a possible etiologic factor in maxillary canine impaction.

A chain of events in the development of the dentition following trauma is described. Shortening of the root of the lateral incisor or displacement of the tooth bud, both as a sequel to trauma, may affect the path of eruption of the adjacent canine after dental injury. Special attention should be paid to the further development and eruption of the directly and indirectly affected teeth.
