According to this review , the 3-step adhesive systems were the best performing and still are the gold st and ard for the cementing of indirect restorations .
In addition , it can be concluded that self-etched adhesive systems reduce the time spent in clinical practice , however at the interface level they behave as permeable membranes more susceptible to degradation
New technologies are changing the therapeutical options to do indirect restorations and new adhesive systems are continuously introduced to be used by clinicians .
Different interactions between restorations , adhesive systems components , enamel and dentin require having criteria based on the selection of the adhesive system , ensuring the longevity of the restorations and the preservation of the biological remnant .
The adhesion force to the dental tissue is one of the indicatives of the behavior of the adhesive systems and influences the behavior of the treatments with direct and indirect restorations .
The objective of this search was to find the adhesive systems with the best results in terms of the adhesion strength of indirect restorations  on the dental tissues .
Bond strength of adhesive resin cement with different adhesive systems
Background To assess the immediate bond strength of a dual-cure adhesive resin cement to the hybridized dentin with different bonding systems . Material and Methods Fifty-six healthy human molars were r and omly divided into 7 groups ( n=8 ) . After 3 longitudinal sections , the central cuts were included in PVC matrix and were su bmi tted to dentin hybridization according to the groups : G1 - etch & rinse system with 3-step ( Apder ™ Scotchbond ™ Multi- Purpose , 3 M ESPE ) , G2 - etch & rinse system with 3-step ( Optibond ™ FL , Kerr ) , G3 - etch & rinse system with 3-step ( All-Bond 3 ® , Bisco ) , G4 - etch & rinse simplified system ( Adper ™ Single Bond 2 , 3 M ESPE ) , G5 - self-etching system with one step ( Bond Force , Tokuyama ) , G6 - universal system in moist dentin ( Single Bond Universal , 3 M ESPE ) , G7 - universal system in dry dentin ( Single Bond Universal , 3 M ESPE ) . Then all groups received the cementing of a self-adhesive resin cement cylinder ( Duo-link , Bisco ) made from a polypropylene matrix . In the evaluation of bond strength , the sample s were subjected to the microshear test and evaluated according to the fracture pattern by optical microscopy . Results The Kruskal-Wallis test suggests a statistically significant difference between groups ( p=0,039 ) , and Tukey for multiple comparisons , indicating a statistically significant difference between G3 and G4 ( p<0.05 ) . It was verified high prevalence of adhesive failures , followed by mixed failure and cohesive in dentin . Conclusions The technique and the system used to dentin hybridization are able to affect the immediate bond strength of resin cement dual adhesive .
