Three Generations of Resin Cements
Cements that employ a total-etch adhesive system
Cements that employ a self-etch adhesive system
Self-adhesive cements (their chemical make-up allows them to bond to tooth structure without the need for any preliminary steps)

Van Der Waals Bonding
Occurs between neutral atoms and molecules
Weak Forces of Attraction: Natural fluctuation in the electron density of all molecules and these cause small temporary dipoles within the molecules that attract one molecule to another. They are called Van der Waals' forces.
The bigger a molecule is, the easier it is to polarize (to form a dipole), and so the Van der Waal's forces get stronger, so bigger molecules exist as liquids or solids rather than gases
These forces are due to the electrostatic attraction between the nucleus of one atom and the electrons of the other
