Advances in manufacturing dental biomaterials have provided clinicians with single-dose systems which apparently simplify the technique while minimizing possible handling errors; however, the findings of the present study showed that the totaletch adhesive system, which requires the application of orthophosphoric acid on enamel and dentin surfaces, was the system with the lowest microleakage degrees, which is explained by the demineralizing process produced after applying 37% orthophosphoric acid on the surfaces, with the subsequent removal of smear layer and fiber collagen exposure at the dentine, allowing better interaction of dental tissue and adhesive system.
