• Abstract:

  The adhesives continue to evolve, as well as the composite resin

  restorations, but need to be constantly evaluated. Ideally, clinical research is better for

  this purpose, but clinically the standardization of protocols is more difficult, increasing

  biases. Thus, a laboratory protocol was made, where some adhesive systems (AS)

  used in the national market were selected for in vitro research. Thirty healthy human

  teeth were randomly selected and distributed in 5 groups: G1 - Âmbar; G2 - Adper

  Scothbond Multiuso; G3 - Clearfil SE Bond; G4 - OptiBond All-In-One e G5 - Vitro Fill

  LC (control). Class V cavitary preparations were made with cervical termination 1.0 mm

  below the amelocementary junction. The AS were used according to the manufacturers

  ‘ instructions and restored with the Opallis composite resin and curing for 20 seconds in

  each increment with the same LED. They were stained with 2% methylene blue for 24

  hours and microleakage was evaluated with a magnifying glass according to the scale

  rating of 0-4. Statistical differences were found in the cervical marginal microinfiltrations

  of G1 restoration in relation to the control group and G2. However, this G1 did not differ

  from groups 3 and 4. The G2 presented the best results, similar to G5. In this way, the

  conventional 3-step AS was the only one with similar results to the control group.
