Shear bond strength of adhesive composite systems to human dentin.
This study was carried out to evaluate the following adhesive systems under different conditions from the point of view of the bond strength that is obtained on dentin: Scotchbond Multipurpose, 3M: Denthesive II, Kulzer; Optibond, Kerr with techniques # 1 and 5; and A.R.T. Bond. Coltene. Composite resin (Z100, 3M) cylindrical specimens were bonded to flat dentin surfaces and the adhesive strength was determined under shear. No significant differences were found between the group in which products were used with a separate step of dentin demineralization and the group in which this step is not recommended or was omitted. It can be concluded that the use of dentin acid treatment as a separate step is not necessarily required for high composite bond strength even when it could represent a convenient clinical step to prepare enamel surfaces simultaneously.
