RESUMO

The aim of the present investigation was to evaluate the microleakage of Class II indirect restorations with composed resin Filtek Z250 and cemented with two types of cements: Adhesive Cement Enforce and RelyX Adhesive Resinous Cement. The experimental sample consisted of twenty-four seconds primary molars. Mesiais and distais cavities were prepared in all the teeth and accomplished the procedures to make indirect restorations. After, they were cemented with two types of resinous cements. Soon after that, the specimes were thermocycled, immersed in 0,5% basics fuchsin and sectioned. The microleakage was measured by a software and assessed the dye penetration at the cervical margins. The results were submitted to the analysis by test “t dependet”. The results demonstrated that none of the tested materials was capable to impede the microleakage completely, and there was no significant differences in relation to the two studied materials.
