The general purpose of this PhD thesis is to define some of the factors influencing the bond of tooth-colored adhesive restorations, considering both enamel and dentin Nevertheless, certain factors such as dentin origin, site and area of bonding affect the bond strength of adhesives. Factors affecting adhesion to mineralized tissue I. Factors that can affect in vitro bond strength to human dentin include substrate (superficial dentin, deep dentin; permanent versus primary teeth; artificial carious dentin), phosphoric acid versus acidic primers, preparation by air abrasion and laser, moisture, contaminants, desensitizing agents, astringents, and self-cured restorative materials. 5 Many of the dentin bonding studies were done on normal human dentin. The durability of adhesive bonding to dentin is influenced by the deg-radation of resin components through hydrolysis of polymerized hydro-philic resin and destruction of collagen matrix by matrix metalloproteinases J Am Dent Assoc. It was feared that removal of the smear layer and subsequent wetting of the dentin surface would affect bond strength between dentin and composite, as the dentinal fluid would dilute primer and bonding agents [ 41] and as water contamination of bonding was known to lower the bond strength [ 42 ]; however, several contemporary systems can cope with augmented fluid permeability of dentin after … Current developments in dentin bonding systems: major progress found in today's products. Four generations of total-etch (fourth, fifth) and self-etching (sixth, seventh) bonding agents for use with resin composites are commercially available in the United States. Keywords: Bonding agents; meta-analysis review; self-etch adhesive. The stability of the dentin-resin interface is a necessary requirement for the durability of restorations; thus, different strategies have been proposed to control the different factors that result in its degradation.
