Resumo
Objetivo: Apresentar uma revisão comparando cimentos resinosos autoadesivos e convencionais na cimentação de pinos de fibra de vidro (anatomizados ou não), à dentina radicular de dentes tratados endodonticamente. Métodos: Mensurar através da aferição da resistência de união por testes push-out ou pull-out. Resultados: Foram analisados estudos publicados entre 2014 e 2024 que utilizaram os testes de push-out e pull-out para medir a força de adesão dos cimentos. A revisão identificou que, em 62,5% dos estudos, os cimentos autoadesivos apresentaram maior força de adesão, enquanto os cimentos convencionais foram superiores em 37,5% dos casos. Fatores como a metodologia dos estudos e a anatomia do canal radicular, assim como as propriedades dos cimentos, podem influenciar nos resultados dos artigos revisados neste estudo e consequentemente ter um papel ativo nesses valores de variabilidade. Considerações finais: Tanto os cimentos convencionais quanto os autoadesivos têm suas vantagens e limitações, e a escolha do material deve considerar fatores clínicos específicos, como a profundidade do canal radicular e a complexidade da técnica de aplicação.
