The Role of the Composition of Adhesive Systems on Adhesive System-Tooth Surface Adhesion

Adhesive systems have been recently classified as etch-and-rinse, self-etch and glass ionomer adhesive systems according to their adhesion strategies. Some advantages and deficiencies were noted for all of these adhesion approaches, mainly for the simplified ones due to some chemical associations and interactions. Keeping an updated knowledge of the composition, characteristics and mechanisms of adhesion of the currently available adhesive systems as well as knowing how the dental substrates interact with these materials are essential to achieve the best results in adhesion. This literature review article addresses the types and the main components of different etch-and-rinse and self-etch adhesive systems available in the market, and relates them to their function and possible chemical interactions. The understanding of the role of adhesive materials in the adhesion process has helped researchers and manufacturers developing and improving dental adhesion
