Abstract
Optimal strategies for the application of an adhesive differ between enamel and dentin because of the differences in their composition. The development of adhesive systems has mainly focused on the bonding of dentin, rather than on the enamel, by etching with phosphoric acid (PA). Dental adhesive technologies continue to rapidly advance, and various adhesive systems have been developed since the study of Buonocore in 1955. He introduced the enamel acid-etch technique. Then, the etch-and-rinse (ER) system was developed, and subsequently, the self-etch (SE) system. Universal adhesives are a new generation of one-bottle SE adhesives that can be applied with either ER mode or SE mode, or a combined system involving selective enamel etching mode. Since the combination of PA etching and the SE system differs from conventional ER systems, the enamel bonding strategy should be carefully considered. This concise review of the literature on reliable enamel bonding strategies should prove helpful to clinicians to choose an appropriate adhesive system to achieve optimal clinical outcomes.

Adhesion largely determines the success or failure of composite resin (CR) restorations
Various adhesive systems have been developed for reliable CR restorations [1,2,3,4,5,6,7,8,9,10,11,12,13,14], each product has unique characteristics that must be considered in clinical practice
This study suggested that deep jaggedness created by phosphoric acid (PA) etching on the enamel surface renders a challenge to water and solvent evaporations [94]
Summary
Adhesion largely determines the success or failure of composite resin (CR) restorations. Various adhesive systems have been developed for reliable CR restorations [1,2,3,4,5,6,7,8,9,10,11,12,13,14], each product has unique characteristics that must be considered in clinical practice. It has been considered that these incompletely infiltrated collagen fibrils in the over-etched dentin are susceptible to degradation by matrix metalloproteinases [18], which are activated by PA etching [19]. To address this issue, selfetch (SE) systems for adhesion to both enamel and dentin without PA etching were developed, which are used worldwide. The aim of this article is to summarize the current knowledge of reliable enamel bonding in CR restoration via a review of the literature
