Current Status and Role of Dental Polymeric Restorative Materials
Mary Anne S. Melo in Designing Bioactive Polymeric Materials for Restorative Dentistry, 2020
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).
Tooth Whitening Materials
Linda Greenwall in 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.)
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).

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.

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.
Marginal gap and fracture resistance of CAD/CAM ceramill COMP and cerasmart endocrowns for restoring endodontically treated molars bonded with two adhesive protocols: an in vitro study

Hydrofluoric acid and silane were used for treating the Cerasmart endocrowns, whereas sandblasting was used to treat the Ceramill COMP endocrowns. The Academy for Adhesive Dentistry reported that hydofluoric acid (HF) etching in combination with silane is a superior pretreatment method for CAD/CAM polymer-infiltrated ceramics.[33] This recommendation is consistent with the results obtained by Elsaka[34] and Frankenberger et al.[35] Sandblasting may cause microcracks in the surface, which may lead to premature failure. It also influences the internal and marginal adaption.[34] HF leads to micro-porosities on the treated surface, thereby increasing the surface area and enhancing the mechanical interlocking with luting cement; silane acts as a coupling agent between the restoration and the resin bond. The use of HF and silane have been reported as the preferred surface treatment method in several in-vitro studies.[36]
