Autotransplantation of teeth with complete rhizogenesis: a literature review

Abstract

Palavras-Chave:Endodontia. Autotransplante. Rizogênese Completa.RESUMO Objetivo: O objetivo da presente revisão da literatura foi verificar as taxas de sucesso, assim como seus fatores predisponentes, do autotransplante dentário em dentes com rizogênese completa. Métodos: Uma busca eletrônica foi executada no PubMed usando MeSH terms e termos livres específicos. Inicialmente, um total de 115 títulos e resumos foram identificados. Um estudo adicional foi identificado como relevante após uma busca das listas de referência. Após a aplicação dos critérios de elegibilidade, apenas 8 artigos foram selecionados. Resultados: De forma geral, os estudos incluídos demonstram elevadas taxas de sucesso, baseado nos parâmetros estabelecidos, como manutenção do ligamento periodontal, cicatrização periapical e saúde periodontal. Além disso, os estudos selecionados na presente revisão apontaram que fatores como os protocolos de extração e reimplante, o tempo de proservação utilizado no estudo e o tempo no qual foi realizado o tratamento endodôntico do elemento transplantado, podem afetar a taxa de sucesso do autotransplante dentário. Conclusão: De acordo com a presente revisão de literatura pode-se concluir que embora ainda existam poucos estudos de autotransplante realizados em pacientes com rizogênese completa, a técnica tem se mostrado uma opção viável e com moderada taxa de sucesso para a substituição de elementos dentários perdidos. ABSTRACT Objective:The objective of the present literature review tis o verify the success rates, as well as the predisposing factors, associated to success rates of dental autotransplant treatments in teeth with complete rhizogenesis. Methods: An electronic search was performed on PubMed database using MeSH terms and free terms. Initially, a total of 115 titles and abstracts. An additional study was identified as relevant after a search of reference lists. After eligibility criteria appliance, only 8 articles were selected. Results: In general, the included studies show high success rates, based on established parameters such as periodontal ligament maintenance, periapical healing and periodontal health. In addition, the selected studies pointed out that factors such as extraction and reimplantation protocols, the time of follow-up used in the study and the time in which the endodontic treatment of the transplanted element was performed, can affect the success rate of dental transplant therapy. Conclusion: According to the present literature review, it can be concluded that although there are still few studies of autotransplantation performed in patients with complete rhizogenesis, the technique has proven itself as a viable option with moderate success rate for replacement of lost dental elements.

Success of a tooth auto-transplant despite delayed endodontic treatment due to COVID-19 pandemic lock-down: a case report

“…A permanent posterior tooth is commonly lost due to caries or periodontal disease [1]. Some people might have one or more permanent teeth missing congenitally.…”

“…Another endogenous method of replacing a lost tooth is auto-transplantation i.e., using a patient's own tooth that is not of much use in the dentition, such as an impacted third molar/permanent canine [4]. Not many cases have been reported on autotransplantation of third molars with complete "rhizogenesis" [1]. Rhizogenesis can be defined as the completion of root formation of a tooth.…”

“…Previously it was regarded that instances of successful auto-transplantation cases were due to incomplete rhizogenesis. But in respect to current reports, it is observed that even with complete mature root rhizogenesis, auto-transplantation has proven to be successful [1]. Tooth autotransplantation with complete and incomplete rhizogenesis is reported to have a success rate of up to 90% [5].…”
