Delayed replantation of avulsed permanent maxillary central incisor - with unfavorable outcome after 12 months

Delayed replantation of avulsed permanent maxillary central incisor: Case report with 6‐year follow‐up

“…3,19 A meta-analysis conducted by Souza et al have found the incidence of internal root resorption to be 1.2%, surface root resorption to be 13.3%, inflammatory root resorption to be 23.2%, and replacement root resorption to be 51%, which shows that resorption in any form is inevitable sequelae of a replanted tooth. 6,7,25,26,29,30,34 In delayed replantation cases, root resorption is common. 3,38 In the present case, the occurrence of replacement root resorption within a month of replantation might have been due to the prolonged extraoral dry time that resulted in the destruction of PDL cells.…”

“…Apart from cultured PDL cells, PDL stem cells, bone marrow mesenchymal stem cells, adipose-derived stem cells, and other induced pluripotent stem cells have shown favorable results in reestablishing the formation of PDL cells. 24 Different literatures have presented cases in which delayed replantation had been attempted, [6][7][8][25][26][27][28][29][30][31] but most of them being <72 h of extraoral dry time, and the replanted teeth serving its function for years. 6,7,[25][26][27][28][29][30][31][32][33][34] Storage medium enhances the healing outcome of the replanted teeth.…”

Different materials/solutions like Hank's Balanced Salt Solution (HBSS), Eagle's Medium, milk, ViaSpan, Eurocollins, Minimum Essential Medium, Gatorade, Custodiol, Dubelco's storage medium, propolis, tooth rescue box (Dentosafe), conditioned medium, contact lens solution, tap water, egg white, saliva, normal saline, saliva extract, green tea, red mulberry, ricetral, and coconut water are used as storage media.…”
