Abstract

Background: Avulsion is considered one of the most serious dental injuries known. Among the parameters studied with respect to the pulpal healing were development of pulp necrosis, pulp canal obliteration (PCO) and the ingrowth of bone into the root canal.

Case Report: This study discusses an immature avulsed permanent maxillary left central incisor which was replanted within 2 hours after stored in a physiologic medium of an eight-years-old boy. Thirteen months after avulsion, a radiopaque material was observed inside the root canal. Six months later, 19 months after avulsion, the root canal was filled completely with bone-like tissue with an internal PDL-like structure surrounding.

Follow-up: The tooth was followed up 3 years after the replantation with bony metaplasia inside the root canal and no other clinical and radiographic findings.

Conclusion: The bony metaplasia is reviewed less than other types of healing. Important to know, it is related to regaining vitality and could comprise partial root's development, in which endodontic treatment should not be consider and therefor follow ups are acceptable, of course when no other pathological signs exist.
