Bonding system is one of the branches of dental restorative dentistry, and its primary aim is to provide retention of restorations, typically composites, to the natural substance of teeth enamel and dentin. Historically, adhesive dentistry can be traced to 1955 when Dr. Michael Buonocore first demonstrated the bonding of acrylic resin to etched enamel (Buonocore 1955). Since then, adhesive technology has evolved rapidly in the following years. By now, the bonding system has evolved to the seventh generation, from no-etch (first-generation) to total-etch (fourth- and fifth-generation) to self-etch (sixth- and seventh-generation) systems (Freedman and Leinfelder 2002; Kugel and Ferrari 2000). These advances have led to a large number of commercial adhesives, providing great convenience and satisfactory performance in clinical applications Beyth et al. (2007), Breschi et al. (2010).
Influence of selective etching on marginal filtration of self-etching adhesives

Since the development of the adhesive dentistry, and the improvement of the adhesion of the bio-materials to the dental tissues, the clinical treatments are being increasingly more conservatives (Gupta, N. et al. 2015).
Tooth Whitening Materials
Published in Linda Greenwall, Tooth Whitening Techniques, 2017
Dentin bonding may be altered after whitening (Della Bona et al. 1992) and the smear layer may be removed (Hunsaker et al. 1990). The bonding between glass ionomer and dentin may also be affected (Titley et al. 1991). This may be a result of the precipitate of hydrogen peroxide and collagen that forms on the cut dentin surface after tooth whitening. It is suggested that adhesive dentistry be delayed for 2 weeks after whitening (Powell and Bales, 1991). (See further discussion later.)

In recent decades, adhesive dentistry has grown quickly. Since the use of modern dental materials produces results that are superior to those of conventional ones, a number of novel and creative treatments have replaced traditional treatment approaches. The development of fiber-reinforced composite (FRC) posts as a reliable substitute for prefabricated metal posts marked a turning point in the field of dentistry [1,2]. Their modulus of elasticity being similar to dentin and their ability to bond to luting cement and tooth structure have been suggested to reduce the likelihood of root fractures most commonly associated with endodontically treated teeth (ETT) restored with metal posts [3]. This coupled with their superior esthetics and easy retrieval adds to their many advantages, making fiber-reinforced posts the material of choice in routine dental practice.
Analysis of laboratory adhesion studies in eroded enamel and dentin: a scoping review

This scoping review was conducted according to the PRISMA-Scr Statement criteria (Preferred Reporting Items for Scoping Reviews) [29]. To identify the primary review question, the PCC framework of the Joanna Briggs Institute was adopted, where P (Population) was defined as restorations in enamel/dentin, C (Concept) was defined as bonding to eroded enamel/dentin and C (Context) were laboratory studies [30]. A search strategy was developed for OVID (EMBASE), Medline/PubMed and Scopus databases, with keywords obtained from Medical Subject Headings (MeSH) and additional free keywords. These were combined with Boolean operators as follows: ((Dental erosion) OR (Tooth erosion)) AND (Adhes* OR Bond* OR Materials testing OR Tensile strength OR Dental bonding* OR Dentin-Bonding Agents* OR resin-dentin). The electronic search covered peer-reviewed papers that were published in the last 10 years (2010–2020), as ideas in adhesive dentistry are rapidly abandoned, the most relevant research will be the latest. There was no language restriction. The last search was conducted on 16 September 2020. Records were retrieved and potentially relevant titles and abstracts were selected, followed by full-text reading and inclusion.
The adverse effects of radiotherapy on the structure of dental hard tissues and longevity of dental restoration

Adhesive dentistry refers in micromechanical interlocking of the infiltrated adhesive system in the microspaces obtained in enamel and the collagen fibrils exposed in dentin by etching, forming the hybrid layer (Breschi et al. 2008; Pashley et al. 2011; Bedran-Russo et al. 2017). Its stability depends on the strategy used to condition these tissues, the infiltration capacity of the monomers of adhesives systems, and the conformation of the polymer network, among other factors (Breschi et al. 2008). To achieve hybridization, the etch-and-rinse (ER) and self-etch (SE) adhesive strategies through phosphoric acid (30%–40%) or acidic monomers (incorporated in the adhesive system), respectively, carry out the demineralization of the tissue necessary for the infiltration of the substrate by monomers (8). The effectiveness of the adhesives strategies in the different radiation doses and the association of chemical factors of dental hard tissues with the adhesive interface stability over time are unknown until now.
