Good thermal insulation properties as a liner under metal restorations; Opacity – for diagnostic purposes on radiographs. Low film thickness (maximum 25 microns acc. to ISO 9917-1). Low allergy potential; Low shrinkage; Retention – if an adhesive bond occurs between the cement and the restorative material, retention is greatly enhanced.
Adhesive dentistry is a branch of dentistry which deals with adhesion or bonding to the natural substance of teeth, enamel and dentin.It studies the nature and strength of adhesion to dental hard tissues, properties of adhesive materials, causes and mechanisms of failure of the bonds, clinical techniques for bonding and newer applications for bonding such as bonding to the soft tissue.

Cyanoacrylate-based glue has a weak bond with smooth surfaces and as such easily gives to friction; a good example of this is the fact that cyanoacrylates may be removed from human skin by means of abrasives (e.g. sugar or sandpaper).
Adhesives may be broadly divided in two classes: structural and pressure-sensitive. To form a permanent bond, structural adhesives harden via processes such as evaporation of solvent (for example, white glue), reaction with UV radiation (as in dental adhesives), chemical reaction (such as two part epoxy), or cooling (as in hot melt).
They also reduce the bond strength of both total and self-etching adhesive systems to dentin if used before an indirect bonding restoration. [36] Another report shows that there is no difference in bond strengths of self-adhesive resin cements to dentine between prior application of eugenol free and eugenol containing provisional cements.

Engineers that rely heavily in the AISC manual for steel construction and AWS D1.1 for guidance have found out that the word “adhesive” appears only three times in the 604-page long AWS D1.1/D1.1M:2015 Structural Welding Code – Steel and only as part of the title of a reference standard (AWS A3.0, Standard Welding Terms and Definitions ...
