Effect of non-thermal argon plasma on the shear strength of adhesive systems

This study evaluated the influence of non-thermal argon plasma applied to dentin on shear strength two adhesive systems. Ninety tooth fragments were embedded in epoxy resin and distributed into experimental groups (n=15): G1 G4 - systems according manufacturers’ instructions; G2 G5 treated with for 30 seconds before hybridization; G3 G6 after hybridization. Cylinders made composite area, specimens submitted test. Higher values observed when applying treatment hybridization (G1: 26.51 MPa, G2: 29.22 G3: 30.27 G4: 22.66 G5: 28.33 G6: 29.32 MPa). The significantly increased regardless application time.
