Successful conservative treatment of dentigerous cyst following intrusion of lower primary incisors.

Abstract

This paper reports on the development of a dentigerous cyst associated with a lower permanent incisor following intrusion of two lower primary incisors. The small root remnant of one of the traumatized primary incisors was associated with granulation tissue, while the second incisor was discolored and suspected of being non-vital. The associated permanent incisor and other adjacent incisors were apically and laterally dislocated from their natural site of eruption. The conservative treatment included extraction of the involved primary discolored incisor, as well as the root remnant, followed by removal of the granulation tissue. After 18 months of follow-up, the permanent incisors were erupting in normal position, without pathological signs of the dentigerous cyst. Following severe traumatic injury to a primary tooth, periodic radiographic follow-up, until eruption of the correspondent permanent tooth, is recommended.
