Resumo: Purpose: To evaluated shear bond strength to enamel of orthodontic brackets bonded with different combinations of composite/adhesive. This study specifically tested an adhesive with antimicrobial agents added to its composition. Methods: Orthodontic brackets were bonded to the flattened enamel surface of 20 bovine incisors. Two experimental group were tested (n=10/group): group 1 (Fill Magic Ortodôntico®/ Magic bond®) and group 2 (Transbond XT®/Clearfil Protect Bond®, which has antimicrobial agents). The specimens were subjected to the shear bond strength test at 1mm/min. The maximum strength recorded to dislodge the bracket was converted into MPa considering the bond area. The Residual Adhesive Index (RAI) was evaluated on the debonded brackets. Results: Group 2 had higher bond strength than group 1 (P=0.001). For RAI assessment, both groups showed failure at the enamel/adhesive interface with retention of most adhesive on the bracket base. Conclusion: The two groups are suitable for bonding orthodontic brackets, and the group with the adhesive containing antimicrobial agents showed higher bond strength than the group with conventional adhesive. Key words: Shear strength; adhesives; products with antimicrobial action

Metodologia: Bráquetes ortodônticos foram colados à superfície planificada de esmalte de 20 incisivos bovinos. Foram formados dois grupos experimentais (n=10/grupo): grupo 1 (Fill Magic Ortodôntico®/Magic bond®) e grupo 2 (Transbond XT®/Clearfil Protect Bond®, que possui agentes antimicrobianos). Os espécimes foram submetidos a ensaio de cisalhamento à velocidade de 1mm/min. A força máxima de deslocamento do bráquete foi convertida em MPa de acordo com a área de união. O Índice de Adesivo Residual (IAR) foi avaliado nos bráquetes descolados. Resultados: O grupo 2 apresentou resistência de união superior ao grupo 1 (P=0,001). Na avaliação do IAR, em ambos os grupos as fraturas ocorreram na interface esmalte/adesivo, com retenção da maior parte do adesivo na base do bráquete. Conclusão: Os dois grupos mostraram-se aplicáveis para a colagem de bráquetes ortodônticos, e o grupo com adesivo modificado com agente antimicrobiano e flúor apresentou maior resistência de união que o grupo com adesivo convencional.
