OBJECTIVE The aim of this study was to evaluate the effects of 4 dentin-bonding agents on the cell viability of bovine derived cells. STUDY DESIGN Cytotoxicity of dentin-bonding agents (G-Bond [GB], Adper Prompt Self-Etch [APSE], Clearfil DC Bond System [CDCB], and Quadrant University-1-Bond [UB]) was analyzed with a dentin barrier test device using 3-dimensional (3D) pulp cell cultures. A co...

objective: considering the use of triple antibiotic paste (tap) for root canal treatment of open apex teeth, this study aimed to assess the effect of tap and calcium hydroxide (ch) on bond strength of composite to dentin.   methods: this in-vitro study was conducted on 32 extracted human premolar teeth. after disinfection with 2% thymol solution, the enamel on the buccal surface of specimens wa...

Dentin-bonding agents have changed dramatically since being introduced. The large number of these products, as well their dynamic nature and myriad clinical uses, make it difficult for clinicians to understand how they work and when to use them. Sequential development of dentin-bonding agents from the mid-1950s to the present is described. Information also is provided about current popular bond...

Conventional water wet-bonding technique has been advocated by many scientists, but the excess water will induce suboptimal polymerization of dental adhesives, phase separation, and nanoleakage, which will influence the longevity of resin-dentin interfaces. Recent studies have put forward a new concept, ethanol wet-bonding. This technique can increase in dentin bond durability. This review focu...

objectives : this experimental study evaluated the effect of bonding application time on the microshear bond strength of composite resin to different types of glass ionomer cements (gics). materials and methods: one-hundred and sixty specimens (two conventional and two resin-modified gics) were prepared and divided into 16 groups. the surface of all specimens was prepared using two different bo...

objective: repair of an indirect restoration is usually preferred over its replacement. this study aimed to evaluate the effect of silane in different surface preparation techniques on the bond strength of direct to indirect composite resin.   methods: for this in vitro experimental study, 48 indirect composite cubes were fabricated, divided into 4 groups of 12 and subjected to the following pr...

Purpose: To compare and evaluate the shear bond strength of three different fifth generation dentin bonding agents used with composite resin and to determine the mode of bond failure in each case. Materials and methods: Forty-five freshly extracted human permanent molars were used and the specimens were divided into three test groups (N = 15) namely group A = Excite, group B = single Bond, grou...

The purpose of the review was to assess the effect of root canal irrigants on dentin bonding. A PubMed-based search was conducted on the articles published from 1980 to 2016. A brief overview and reviewing the effect on dentin bonding of common root canal irrigation solutions such as sodium hypochlorite (NaOCl), chlorhexidine (CHX), ethylenediaminetetraacetic acid (EDTA), mixture of a tetracycl...
