Table 1.

General characteristics of non-adhesive and adhesive cements.

Non-Adhesive Cements	Adhesive Cements
➢ Retention is mechanical. ➢ Need long axial walls of the preparation with slight taper (approx. 6°). ➢ Precise fit of the restoration (approx. 30–100 μm). ➢ Bond strength should be higher than the stress during chewing. ➢ The tooth is cleaned (recommended to use a pumice stone and/or chlorhexidine), thoroughly dried, and coated with a cavity varnish or dentin bonding resin.	➢ Retention is micromechanical and chemical; adhesive bonding between restoration and tooth. ➢ Bond strength is dependent on the stable adhesive interface and bondable materials (tooth surface, restoration, and cement). ➢ Adhesive fixation is also conditioned by environmental control (the absence of moisture). ➢ Bond strength should be higher than the stress during chewing. ➢ The substrate surface is cleaned and treated according to the cement system protocol.
