16‐Year follow‐up of an avulsed maxillary central incisor after replantation following 10‐h storage: An unusual case

Abstract

Tooth avulsion is a type of dental injury defined as the complete displacement of a tooth out of the alveolar socket, and the lack of prompt treatment measures can result in the loss of function, poor quality of life, and psychological and social problems. However, several factors may not permit the immediate replantation of an avulsed tooth; therefore, delayed replantation has emerged as an alternative to meet the esthetic, functional, and psychological demands of patients. Here it was described that the successful replantation of an avulsed maxillary central incisor in a 9‐year‐old boy who presented at the clinic with the tooth stored in unfavorable conditions as dry and then in olive oil‐milk mixture almost 10 h after the event. The tooth has remained in its socket healthy for 16 years after treatment. The patient was satisfied with both esthetics and function.

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

“…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.…”

“…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.…”

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.…”

“…1 Numerous literatures have been published about replantation of an avulsed tooth, but literature reporting replantation after more than 72 h of avulsion with follow-up of more than 5 years are scarce. [6][7][8] The present case report showcases the delayed replantation of a permanent maxillary central incisor after 72 h of avulsion where the avulsed tooth was stored in a dry field before replantation. Clinically, the replanted tooth was asymptomatic till 5-year follow-up visit, but there was presence of pinkish discoloration and slight infraposition on the 6-year follow-up visit.…”

“…Where immediate replantation is not feasible, the extra‐alveolar conditions can be modified by storing the avulsed tooth in a physiological storage medium 1 . Numerous literatures have been published about replantation of an avulsed tooth, but literature reporting replantation after more than 72 h of avulsion with follow‐up of more than 5 years are scarce 6–8 …”
