Abstract
The infection of primary teeth occurs by caries or trauma. But, if it is not treated on time, the complication may occur such as enamel hypoplasia, discoloration, impaction, displacement and dilaceration of permanent successors. The periapical lesion on primary tooth could displace the permanent successors in any direction. Treatment options of displaced tooth are observation after extracting the primary teeth, surgical exposure orthodontic traction, transplantation and extraction.
In these cases, displacement of permanent central incisor caused by the periapical lesion of primary teeth was observed. The spontaneous eruption after extraction of primary teeth was expected considering degree of displacement, development of root and direction of eruption. This case report shows spontaneous eruption of displaced permanent tooth germ was achieved with periodic examination after extraction of primary teeth.
