Survival of avulsed maxillary incisors following delayed replantation

Three years follow-up

Abstract

Abstract

            A 12 year old boy had reported with avulsed 11,12 and 21 after a delay of 12 hours. The avulsed teeth were replanted and splinted using an acid-etch composite splint for 4 weeks. Extra-oral endodontic therapy was performed prior to replantation. Before the splint was removed, the root canals were filled with definite sealer and gutta percha. The patient was followed up at 1, 3, 6 and 12-months interval and half-yearly thereafter. After 36 months of follow-up, the replanted teeth showed slight clinical mobility, but the roots were being replaced by bone on radiographic examination indicating replacement resorption. The case report concludes that avulsed teeth transported in pasteurized milk, replanted after a delay of 12 hours has a survival rate of 36 months. Replacement resorption is inevitable, wherever delayed replantation is attempted. Prolong delayed replantation serves the esthetic purpose for a young adolescent in the interim phase of developing occlusion.
