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 .
The Effects of Different Adhesive Agents on the Shear Bond Strength of a Self-Adhesive Resin Cement
Purpose To compare the clinical success of a self-adhesive resin cement used in combination with different adhesive bonding systems with that of a conventional dual-cure resin cement . Methods The study was performed with 136 freshly extracted molars embedded in acrylic resin blocks and 136 IPS e.max Press discs . Teeth and discs were r and omly divided into four equal groups and cemented together using either RelyX ARC ( ARC ) , RelyX Unicem ( Unicem ) , RelyX Unicem+Adper-Prompt L-pop ( L-pop ) , or RelyX and Unicem+Total-etch ( Total-etch ) . Shear bond strength measurements were obtained before and after thermocycling . Following bond testing , the surfaces of one sample per subgroup ( thermocycled and non-thermocycled ) , were assessed using scanning electron microscopy ( SEM ) . Results Among the non-thermocylced subgroups , ARC exhibited the highest bond strength values , followed by Total Etch , Unicem and L-pop . ARC also exhibited the highest bond strength values among the thermocycled subgroups , followed by Unicem , Total-etch , and L-pop . SEM analysis clearly revealed the negative effects of thermo-cycling on the mechanical properties of adhesive agents . Conclusions RelyX Unicem may be preferable in many cases because of its simplified application and reduced technique-sensitivity
