Resumo

O objetivo foi avaliar a resistência ao cisalhamento por extrusão e verificar o tipo de falha do pino de fibra de vidro que recebeu diferentes tratamentos superficiais para testar o adesivo multiuso Single Bond Universal® (3M ESPE). Oitenta incisivos bovinos com tratamento endodôntico foram divididos aleatoriamente em quatro grupos. Grupo I: os pinos receberam aplicação de silano; Grupo II: sem tratamento; Grupo III: Silano e Adesivo; E Grupo IV: somente adesivo. Os grupos foram submetidos à ciclagem térmica por 5.000 ciclos, as raízes foram seccionadas e submetidas ao teste de push out. Com a silanização e a aplicação do adesivo, a resistência entre o pino de fibra de vidro e a dentina de qualquer um dos terços radiculares foi significativamente menor. A associação silano-adesivo causou danos significativos à adesão. A silanização sozinha constituiu o tratamento que melhorou a adesão. Defeitos adesivos foram os mais prevalentes.
