Dental adhesion

Thus, thought became directed towards developing adhesive dental materials, an approach that has led to considerable successes and has revolutionized restorative dentistry. 

Oxathiocin 771 and related compounds were used to produce polymers, co-polymers, or block polymer to manufacture adhesive, dental compositions, and optical lenses <1996WO 9471>. 

Products and Uses An additive in adhesives, dental cements, deodorants, disinfectants, and taxidermy embalming fluid. On lumber it is used for a preservative and fireproofing. Also used in medicines as an astringent and antiseptic.

Abstract Adhesive techniques and materials are being used increasingly in clinical dentistry, and they are reviewed in the present chapter. Broadly speaking, there are two types of tooth-colored restorative material, the so-called composite resins and the glass-ionomer cements. There are, though, variations on these basic types, as explained in the chapter. In addition, there is the zinc polycarboxylate cement, which was the first adhesive dental restorative material to be developed, and it retains a niche in modem clinical practice. 

Within the field of adhesive dental technology, bonding agents tend to be classified by generation. These are summarized in Table 56.2. 

Zinc polycarboxylate was the first of the adhesive dental restorative materials to be described. It was invented by Smith (1968) who reported that it was fabricated from aqueous polyacrylic acid and deactivated zinc oxide, and that it had excellent adhesion to both dentin and enamel. It was also found to have other desirable properties. For example, it set rapidly with minimal shrinkage, it was bland toward the soft tissues of the mouth, and it was almost completely insoluble in saliva (Smith 1968). Zinc polycarboxylate cement can thus be considered a major development in the field of adhesive dentistry. Typical properties of zinc polycarboxylate cement are shown in Table 56.4. 

The clinical technique known as Atraumatic Restorative Treatment (ART) has been developed since the mid-1980s in response to dental clinical needs in Third World countries. It is an important application of adhesive dental materials, specifically conventional glass-ionomer cements, and would not be possible without this type of adhesive material (Frencken et al. 2004). ART involves the removal of carious tooth tissue with hand instruments rather than conventional dental drills. These hand-held instruments are formed as spoon-shaped excavators, and come in graded sizes. 

Zinc polycarboxylate cement, the first adhesive dental restorative material, is also described, though nowadays it has only niche applications in dentistry.
