Method: Three cases of healthy children with dislocated tooth in mixed dentition were recruited. Informed consent was obtained from the parents before any treatment was given. The avulsed incisors wrapped in tissue were cleansed with normal saline; one visit root canal therapy was performed in vitro with MTA and IRootSP as sealer plus gutta percha points as root canal fillings. The obturated incisors were then replanted and splinted with composite resin and stainless steel wire. Systemic application of antibiotics was prescribed for 5 days. Follow-up intra-oral examination and radiographs taken were used to detect any sign of pathological response timely.
Result: The replanted incisors healed well in terms of function and esthetics, with no signs of gingival swelling, sinus tract formation, periapical radiolucency, root fracture, inflammatory or replacement root resorption.
Conclusion: The up-to-date outcomes of the study indicate, with the development of dental biomaterial, delayed replantation of avulsed permanent incisors of extra-oral time over 10 hours might be a possible interim treatment choice.
