  3. 12. Shear Bond Strength of Composite to Dentine with Various Adhesive Systems

    University essay from Umeå universitet/Institutionen för odontologi

    Author : Edvin Besic; Simon Norstedt; [2023]
    Keywords : ;

    Abstract : ABSTRACT  Background Different dental adhesive systems are used in modern restorative dentistry. Older adhesive systems such as etch and rinse systems of generation 4 have been extensively tested and proven reliable, newer adhesive systems such as self-etch systems of generation 7 and 8 have been developed with the aim of improving bonding performance, durability and to be less technique sensitive.
